Dear fellow members,

I would like to highlight some of the notable achievements of the Singapore Structural Steel Society (SSSS) over the past few years.

First, I am pleased to report that the SSSS has grown in membership. Our individual membership grew from just 245 in 2000 to 550 this year. During the same period, corporate membership also increased from 13 to 136. Of course, size alone is not a sign of greatness. It is what we do together and the results that is important. And in that respect, I can point out quite a few successes of the SSSS.

At the top of this list is the SSSS Steel Fabricators Accreditation Scheme.

Launched in November 2002, this scheme has helped to raise the standards of steel fabrication and erection in the construction industry in Singapore. To be accredited, applicant firms must meet requirements of the category they are applying for. The firm will be audited and inspected to verify their qualifications. This scheme has the strong support of the BCA. They have sent out an advisory note to encourage QPs to specify, as part of their contract specifications, that the steel fabricator employed should be accredited under the SSSS Steel Fabricators Accreditation Scheme. Today, the scheme has accredited just over 100 structural steel fabricators.

The training of Certified Structural Steel Engineers and Supervisors is another worthy SSSS contribution to the industry. In response to the acute shortage of engineers and technical personnel who were trained to supervise structural steelwork, the SSSS launched the Certification Course for Structural Steel Engineers and Steel Supervisors a few years ago. They are specially tailored for engineers and technical personnel working in the steel fabrication yards and on construction sites. The courses emphasise the practical and safety aspects of structural steel construction and have been very well attended. To-date, we have trained over 700 qualified steel supervisors and about 300 engineers.

The third project I want to mention is our SSSS-BCA scholarship. This is our society’s contribution to the efforts to attract more talents to the construction sector. The scholarship fund is to assist deserving undergraduates pursuing Civil and Structural Engineering course at NUS or NTU and diplomas at Singapore Polytechnic. Started during our 20th anniversary celebration, we have since raised over S$418,000. To-date we have given out six scholarships to university undergraduates and eight to diploma students.

The fourth area of contribution is in helping the industry to switch to the Structural Euro-Codes 3 and 4. Over the past three years, our society has assisted BCA and SPRING Singapore to play a leading role to help the industry prepare for the implementation of the structural Euro-Codes 3 and 4. These are the European Standards for the design of steel structures and composite steel and concrete structures respectively.

Our society took the lead in preparing the National Annexes customised for Singapore usage. The National Annexes are an essential part of the Euro-Codes. This is a great honour for our society and reflects the growing recognition of the SSSS as a respected and value-adding organisation in the construction sector. Going forward, we are preparing training programmes to gear up our steel engineers for the switch. They should be ready next year.

I would like to conclude by thanking my fellow council members who have worked tirelessly to contribute to these achievements. Apart from the projects which I just mentioned, they are the reasons why the SSSS is so active. Every month, we have at least one, sometimes two or three activities such as site visits, evening talks, seminars or corporate members’ nights. But most of all, we thank all our members, whether individual or corporate, whose participation and strong and constant support have made all these achievements possible.

We look forward to your continuing support in the years ahead.

Warmest Regards,

Tan Tian Chong

STEEL DESIGN AWARDS 2010: Promoting the Use of Steel in Construction

Since 2002, the Steel Design Awards have recognisd steel structural engi-neering excellence, and rewarded the

work of the most talented structural design-ers/architects and steel fabricators for their indispensable contribution to the built envi-ronment. This event was previously held in 2002, 2004, 2007 and 2009.

The greatest challenge in the coming years for the construction industry is to remain profitable and competitive. For the steel sector, this is the golden opportunity to demonstrate the advantages of steel design and construction. Many developments are hard pressed for materials, time and workers. Steel designers and related practitioners who come out with innovative designs on cutting edge steel building technology to fast-track construction and at the same time to reduce the number of construction workers required will be the most sought after.

The SSSS Steel Design Awards allows one to have the opportunity to be associated with the continuing growth and success of this premier celebration of achievement and innovation in steel structural engineering.

It is a fantastic opportunity to raise the profile of your organisation within the industry and the general public. It also acknowledges your efforts contributed by the project team.

What type of projects is suitable?

The SSSS Steel Design Awards is opened to both large and small-scale projects. Judging is based on merit and not on the size of the projects. The intended project for entry should have been completed or be due for completion between April 2008 and 30 April 2010. The SSSS Steel Design Awards’ categories are designed to reflect the breadth of projects for which our designers or steel fabricators are responsible for in Singapore.

For the 2010 SSSS Steel Design Awards the committee has decided to divide into 3 different categories, reflecting the breadth of projects for which structural engineers and steel fabricators are responsible. They are as follow:



The HelixThe HelixThe architectural and engineering

marvels behind The Helix provide nothing short of a magical and

intriguing experience for bridge users. As the bridge is designed to curve to connect seamlessly with the pedestrian promenade at the Bayfront and Marina Promenade, bridge users can see the entire structure of the bridge while crossing it. The 280m bridge, comprising five spans (three internal spans, each 65m and two approach spans, each 43m), forms part of a 3.5km waterfront promenade that loops around the Marina Bay.

Crossing the 6m-wide bridge is a unique experience as fitted glass and steel mesh canopies dotted along the inner spirals, providing shade from Singapore’s tropical climate. Four viewing pods extend out over the water. Positioned in strategic locations, these platforms let visitors enjoy the expansive skyline vista while watching events by the water and shoreline. Glass panels on the floor also provide a visual connection to the water below.

The design inspiration behind The Helix is entirely forward-looking: its resemblance to DNA as a symbol of continuity, renewal, and everlasting abundance, reflects Singapore’s aspirations for Marina Bay.





Sands® SkyPark® is one of the iconic features of the Marina Bay Sands® Integrated Resort (MBSIR) located

in the Marina Bay area. The 1ha SkyPark® sits atop three 55-storey hotel towers and includes facilities such as landscaped gar-dens, signature restaurants, infinity pools and a 65m cantilevered viewing platform which offers visitors a 360° view of the city. The SkyPark® is the world’s largest cantilevered public observation deck – it measures 38m wide, 340m long and used over 7,000 tonnes of steel in its construc-tion. The extraordinary SkyPark® is now a landmark, and a symbolic icon for Sin-gapore, similar to what the Sydney Opera House is to Sydney.

The superstructure is likened to a bridge that sits atop three 55-storey hotel towers. Notably, the most challenging aspect of is the 66.5m long SkyPark® cantilever that overhangs from hotel tower 3. As the experts behind the engineering works of Sands SkyPark, Arup spent considerable time to conduct various stress tests. Much time and analytical effort was spent by Arup’s bridge and dynamics specialists to ensure we understood the complex behaviour under wind and human excitation (dancing etc).

by people movement. The dynamic properties of a structure are particularly hard to predict as there are many elements of the structure and architectural finishes that contribute to this. Arup thus designed large tuned mass dampers that act in a similar manner to shock absorbers within the SkyPark®’s belly and carried out large scale vibration tests to verify the design.

Arup had to overcome a number of structural challenges, the first of which was to formulate a design that allowed for safe and easy erection so far above the ground. This was achieved through a combination of bridge and building technology. The second was to cater for the natural movements of the towers upon which the SkyPark® was to be supported, through the composition of five distinct joined plates. The third challenge was the dynamics of the SkyPark® in response to strong winds and vibration caused



Marina Bay Sands Podium Roof & Canopy Structures


October- December 2010 STEEL News & Notes 17

The Marina Bay Sands® (MBS) Integrated Resort is aimed at becoming a key element in

Singapore’s tourism market, and is an icon for the island’s Marina Bay redevelopment. MBS integrates the waterfront promenade with civic space, shopping, indoor and outdoor spaces endowed with city skyline views, daylight and plant life, to provide an abundance and variety of activities.

This development comprises state-of-the-art Meetings, Incen-tives, Conventions and Exhibitions (MICE) facilities, a massive events plaza, two theatres and a multi-level retail arcade lining the water-front promenade. Enclosing these striking buildings are the stepped, wave form Podium Roof & Cano-py Structures. Every component of this development is technically challenging.

The Podium Roof comprises long span roofs enclosing the Casino, Theatre and MICE facilities. They span up to 120m and exhibit highly-complex stepped, wave form surfaces. The retail arcade is sheltered by various lightweight canopy structures, some of which have plan dimensions of 45x90m, and are connected to pedestrian bridges spanning 60m. The canopies have a double curved geometry and are cable-stayed back to the Podium concrete structure.

COMPOSITE CONSTRUCTION FOR SUSTAINABILITY

Special Feature

In terms of construction, the advantages of steel-concrete composite include longer spans and column free space; thinner and lighter building weight; smaller column

size; reduction of storey height reduces the total cladding area of the building lead to cost saving for cladding; and fast-track construction. Saving costs include earlier completion and thus increasing rental income; lower financing costs etc.; flexible M&E layout and facilitate future maintenance and upgrading.

Buildable design of high-rise building standardisation allows for repetition of grids, stan-dardised sizes of components and connection details. It also of-fers simplicity - simple building construction systems and instal-

lation details. Speed of construc-tion is achieved via exploitation of long span advantage; reduces number of floor joints, integrate building services and adoption of composite construction.

Professor Liew pointed out that today’s newer high perfor-mance steels (HPS) include fire-resistant steels, seismic steels, off-shore structures steel, low-yield steels, very high-strength steels, hot versus cold formed steel, and structural stainless steels. Current concrete grout and ultra-lightweight concrete feature high-strength and high

performance, especially when used with HPS.

Aspects of sustainable tall buildings according to Professor Liew include building

At the Tall Buildings Asia confer-ence held 30-31 August 2010 at M Hotel Singapore, Professor JY Richard

Liew’s presentation concerned how building materials such as concrete and steel can be used in conjunction via ‘composite construc-tion’ technology and application.

He began his talk saying that we spend 90% of our lives in buildings - work, leisure and home. Hence, it is easy to see that productivity, well-being etc., is linked to the built environment which surrounds us every day. The idea of ‘composite construction’ involves steel and concrete as these two materials complete one another. Namely, concrete is efficient in compression and steel in tension. Concrete encasement restrains steel against buckling, and protects against corrosion and fire damage. Steel brings ductility into the structure.

efficiently, building for future flexibility, building for durability, designing for efficient operation, and designs that consider end-of-life and waste elimination issues.

The role of engineers in sustainable design include such aspects as low carbon foot-print and environmental impact such as embodied energy, CO2 emission, water use and pollution etc. Other aspects include design for recycling such as efficiency; reduced wastage;

reduce energy consumption of building; adaptability, durability; and reuse without major modification and demolition.

The new Solar Thermal Water Tank


Façade/Wall System presented by Professor Liew in his speech offers such green aspects as reduced energy demand for air-conditioning and lower energy bills along with increasing the indoor thermal comfort of a building. The system also reduces energy consumption required for heating water, reduces greenhouse gas emissions through less electricity consumption in addition to reduciong the urban heat island (UHI) effect and harness solar energy by an affordable

façade system. It is also a good replacement to commonly used conventional brick/façade walls.

Professor Liew’s conclud-ing remarks included seeing construction as essential in today’s sustainable develop-ment. Today, the engineers’ role is important to ensure sustainable design. A very broad holistic approach / life cycle analysis should be used, and the proper choice of ma-terial and specification can provide positive contribution towards these goals.

Composite Columns Infilled with Ultra-high Strength concrete

Normal Strength Concretefcu < 60MPa

High Strength Concrete60MPa < fcu < 105 MPa

Ultra High Strength Concrete 105MPa < fcu < 200 MPa

Therefore, composite columns for high-rise construction improves space efficiency by using smaller columns in addition to utilising synergistic material advantages (composite action) resulting in higher strength and ductility, good fire and corrosion resistance, and fast-track construction (cost and time savings).

Special Feature

Some people feel that once in place, concrete bridges (reinforced and pre-stressed) last forever and that steel bridges are slowly corroding away. Indeed the perception is that concrete is an inert material which is less vulnerable to the environment than structural steel.

First, virtually all steel bridges include concrete components such as deck and/or substructure. In many cases what is labeled deterioration of a steel bridge in fact, involves the concrete components. Concrete deterioration is a subject that has been widely researched but not so widely discussed. According to the Organization for Economic Co-Operation and Development (OECD)

some of the important causes of deterioration of concrete in bridges are:

Chloride contamination by de-icing • salts, saline air and seawater;Sulphate attack;• Thermal effects (freeze/thaw action);• Poor quality concrete;• Insufficient concrete cover;• Lack of maintenance;• Alkali-silica reactions;• Ineffective drainage;•

Any combination of these factors, such as the use of de-icing salts in a freeze/thaw climate with ineffective bridge drainage can greatly accelerate the deterioration of the bridge, be it concrete or steel. One item mentioned above, alkali-silica reaction

ASR, has been cited by the Strategic Highway Research Program, as a major cause of cracking and deterioration in concrete structures in the United States.


Feature Article

This article wishes to dispel some of the “myths” or misconceptions surround-ing the use of steel in bridge construc-

tion. These myths often arise out of past expe-rience and don’t take into account changes in technology, improvements in materials and products or updated design and construction practices.

Adhering to these myths can limit the competitiveness of steel solutions, lead to misuse of steel products or prevents designers and owners from taking advantage of viable options when it comes to providing crossings. The original document focused primarily on signature bridges of steel plate girder construction. The newer document has been expanded to include prefabricated/modular steel bridges using steel rolled beams and hollow structural sections and also corrugated steel pipe and corrugated steel plate as viable materials for bridge construction.

What follows is not intended to be an exhaustive treatise on the technical aspects of steel bridge design but rather to help designers and owners take full advantage of steel in their search for viable solutions. To the extent possible we have provided references as back up and as sources for additional information.

Myth: Concrete lasts forever without maintenance.

reALity: Concrete is affected by the same environmental deterioration factors as steel. Its performance is also affected by quality of materials and design.

&Steel Bridge Construction:

MythsA FewRealities

ASR is a reaction inherent in concrete that causes it to expand and crack based on three elements in the concrete: 1) reactive forms of silica or silicate in the aggregate, 2) sufficient alkali (sodium and potassium), primarily from the cement and 3) sufficient moisture in the concrete. The combination of the silica and alkali produce a gel reaction product. When this gel reaction product encounters moisture it expands resulting in cracking of the concrete.

In arid desert-like regions lack of moisture causes the ASR gel reaction product to

shrink, which also produces cracks in the concrete. Although the symptoms of cracking and distress may be caused by external factors such as freezing and thawing, corrosion of reinforcing steel or plastic shrinkage, ASR is a process that occurs within the concrete itself.

Stein Rostam in “Concrete International” made another in-depth presentation of concrete deterioration. In his article Rostam describes carbonation, the process by which CO2 is absorbed by concrete gradually reducing the alkalinity to a point where reinforcing steel loses the corrosion protection afforded by an alkaline concrete. Rostam also described chloride intrusion that

attacks concrete in marine environments and whenever salt is used as a de-icing agent. In the latter case the concrete is also subjected to freeze shock causing small cracks that gradually allow chloride laden moisture to penetrate the body of concrete and attack the reinforcing steel.

The result—spalling and loss of reinforcing itself—may not be evident initially.

An article in the April 2007 issue of the Journal of Protective Linings and Coatings titled “Concrete Bridges: Heading Off the Impending Durability Burden,” Bob Kogler of Rampart, LLC makes the following points:

*The demands of increasing age, traffic loading and the increased use of road salts has made the durability of bridge structures of all types more difficult.

*The increase in the number of bridges using pre-stressed concrete structural elements has led to a large number of bridges where the high-strength steel pre-stressing strands are

designed and detailed according to the published FHWA and Industry guidelines for its use. There are many cases of weathering steel bridges not conforming to the guidelines that are also performing well.

When used properly, uncoated weathering steel is by far the most cost-effective material for bridges when considering either first or long-term costs. Over the years there have been some isolated problems due to a lack of understanding of the material and its subsequent misuse. The fact remains that weathering steel is acceptable in most locations. Because of isolated problems, however, it became clear that guidelines on the use of weathering steel were needed so that owners could enjoy its economic benefits with confidence.fhWA gUiDeLineS

In 1988, the FHWA conducted a “Weathering Steel Forum” to establish these guidelines. This forum brought together state departments of transportation to discussed their positive and negative experiences with weathering steel bridges.

The outcome of this forum was the FHWA “Technical Advisory—Uncoated Weathering Steel in Structures” in 1989. (These guidelines,

although still valid, are currently being reviewed by FHWA and supplemented with more data.) In accordance with these FHWA guidelines, there are four considerations that must be taken into account when considering the use of weathering steel:

Environmental and Site Conditions• Location• Design Details for Proper Drainage• Maintenance•

An evaluation of atmospheric and site conditions at a particular site should be made before uncoated weathering steel is considered. The steel industry offers services to help owners evaluate such factors as marine atmosphere, annual rainfall, prevalence of fog, and atmospheric and industrial pollutants in order to determine whether site conditions are suitable for the use of uncoated weathering steel. Some of these factors such as saline atmosphere can adversely affect the performance of any bridge material.

Excerpt from American Iron & Steel Institute publication D432-07.


protected from the environment and corrosion by only an inch or two of concrete cover.

*Corrosion of steel strands is a major factor in a significant number of bridges in the FHWA Bridge Management Information System inventory being classified as structurally deficient.

*There is a long-overdue need to consider protective coatings for concrete structures as well as targeted corrosion prevention solutions for new and existing structures.

The American Concrete Institute also recognizes that concrete structures are subject to deterioration. It recommends sealing of concrete surface to reduce permeability, considered to be the single most important factor affecting the rates of deterioration from reinforcing bar corrosion, carbonation, alkalisilica reaction or freeze-thaw cycle, all of which may be occurring simultaneously.

When this type of internal deterioration occurs it is very serious; the solution is expensive repair or bridge replacement. Such hidden defects in a concrete bridge are often extraordinarily difficult to detect and can lead to catastrophic collapse such as happened in 2006 to a bridge in Quebec, Canada. Built in 1970 the collapse was blamed on misplaced or missing or short rebars; probably at the girder dapped ends, something virtually impossible to detect once the bridge was completed.

Structural steel deterioration on the other hand is visible and any signs of corrosion are clearly apparent which creates the impression that steel is maintenance prone. However, steel is easily repairable at almost

any stage of corrosion and over the years has shown a remarkable tolerance to lack of maintenance.

Myth: Concrete bridges outlast steel bridges.

reALity: There is no credible statistical evidence to support the notion that concrete bridges outlast steel bridges.

In comparing the relative durability and service life of concrete vs. steel bridges, attempts have been made to show that concrete outlasts steel when in fact the first

major pre-stressed concrete highway bridge (the Walnut Lane Bridge in Philadelphia) was replaced after a service life of approximately forty years. Of course, there are examples of ill maintained and badly deteriorated steel bridges that have also been replaced. There are also many steel bridges with over 100 years of service life that are still performing adequately.

Perhaps the truest picture is presented in an exhaustive study conducted at Lehigh University in 1992 by Professors David Veshofsky and Carl Beidleman. They analyzed deterioration rates for, at the time, the approximately 577,000 bridges listed in the Federal Highway Administration (FHWA) National Bridge Inventory. Their conclusions were 1) that superstructure material type was not an indicator of the life expectancy of a bridge, 2) age is the primary determinant of deterioration and 3) average daily traffic is the second most important determinant of deterioration.

More recently in an article titled “Enduring Strength” published in the September 2003 issue of Civil Engineering the authors point out existing and potential problems with post-tensioned concrete bridges. Corrosion of post-tensioning tendons was found in a significant number of recently constructed bridges in Florida and other US states. Extensive non-destructive testing and inspection by use of a fiberscope, performed at considerable expense, revealed corrosion of strands because of improper grouting procedures

and exposure of strands at bridge joints to saline atmosphere or de-icing chemicals.

It seems that bonded pre-stressing tendons are susceptible to errors that are difficult to detect and that can lead to serious structural problems. Once again, problems with steel bridges are usually ones of details such as joints and bearings.

Myth: Weathering steel performs only under ideal climatic conditions

reALity: Weathering steel performs successfully when

Prevention of Corrosion on Structural Steelwork

The cost-effective corrosion protection of structural steelwork should present little difficulty for common applications

and environments if the factors that affect durability are recognised at the outset. This article aims to give specifiers an insight into the factors involved. In dry heated interiors, no special precautions are necessary. Where precautions are required modern durable protective coatings are available which, when used appropriately, provide extended maintenance intervals and improved performance.

the corrosion process Most corrosion of steel can be considered

as an electro-chemical process that occurs in a series of consecutive stages. The details of this process can be summarised by the following equation: 4Fe + 3O2 + 2H2O = 2Fe2O3.H2O (Iron/Steel) + (Oxygen) + (Water) = Rust From this it can be seen that for iron and steel to corrode it is necessary to have the simultaneous presence of water and oxygen. In the absence of either, corrosion does not occur.

What Affects the rate of corrosion? The principle factors that determine the

rate of corrosion of steel in air are the time of wetness and the presence of atmospheric pollution typically present as suplhates and chlorides.

Time of Wetness refers to the proportion • of total time during which the surface is wet, due to rainfall, condensation, etc.

Sulphates originate from sulphur • dioxide gas that is produced during the combustion of fossil fuels

Chlorides are mainly present in • marine environments. The highest concentrations of chlorides are to be found in coastal regions, and there is a rapid reduction when moving inland. Both sulphates and chlorides increase

corrosion rates as they react with the surface of the steel to produce soluble salts of iron that can concentrate in pits and are themselves corrosive.

Because of variations in atmospheric environments, corrosion rate data cannot be generalized; however, environments and corresponding corrosion rates are broadly classified in BS EN ISO 12944 Part 2 and ISO 9223

Feature Article


The Effect of Design on Corrosion Prevention

In external or wet environments, design can have an important bearing on the corrosion of steel structures. In dry-heated interiors, no special precautions are necessary. The prevention of corrosion should, therefore, be taken into account during the design stage of a project. The main points to be considered are (1) To avoid the entrapment of moisture and dirt. The key here is to avoid the creation of cavities and crevices so that welded joints are preferable to bolted joints. Lap joints should be avoided or sealed where possible. Additionally drainage holes to prevent standing water may have to be incorporated. And (2) Coating application--The design should ensure that the selected protective coatings can be applied efficiently. Typically, this might involve ensuring adequate access for painting or adding drain/vent holes to sealed components, which will be subject to hot dip galvanizing.

the Application of protective coatings Surface Preparation The surface preparation

of steel is concerned with the removal of mill-scale, rust and other contaminants to provide a satisfactory substrate for coating and is generally considered to be a two stage process. The first stage of any surface preparation is to remove residues of grease, oil or marking inks. The second stage is to remove any mill scale and rust and is generally done by either hand and power tool cleaning or abrasive blast cleaning.

paintingPainting is the principle method of protecting

structural steelwork from corrosion.

Paints are made by mixing, pigments (the coloured part), binders (the film forming component) and the solvent (which dissolves the binder). Paints are usually applied one coat on top of another and each coat has a

specific function or purpose.

The primer is applied directly onto the cleaned steel surface. Its purpose is to wet the surface and to provide good adhesion for subsequently applied coats. In the case of primers for steel surfaces, these are also usually required to provide corrosion inhibition.

The intermediate coats (or undercoats) are applied to ‘build’ the total film thickness of the system. Generally, the thicker the coating the longer the life and this may involve the application of several coats.

The finishing coats provide the first line of defence against the environment and also determine the final appearance in terms of gloss, colour, etc.

hot Dip galvanizing The most common method of applying a

metal coating to structural steel is by hot-dip galvanizing. Following surface preparation as described earlier the galvanizing process involves the following stages:

I. The cleaned steel is immersed in a fluxing agent to ensure good contact between the steel and zinc during the galvanizing process.

II. The cleaned and fluxed steel is dipped into a bath of molten zinc at a temperature of about 450°C. At this temperature, the steel

reacts with the molten zinc to form a series of zinc/iron alloys integral with the steel surface.

III. As the steel workpiece is removed from the bath, a layer of relatively pure zinc is deposited on top of the alloy layers.

As the zinc solidifies it usually assumes a crystalline metallic lustre,

often referred to as ‘spangling’. The thickness of the galvanized coating is influenced by various factors including the size and thickness of the workpiece, the steel surface chemistry and the surface preparation of the steel.

Weathering SteelsWeathering steels are high strength, low-

alloy weldable structural steels that possess good weather resistance in many atmospheric conditions without the need for protective coatings. They contain up to 2.5% of alloying elements, e.g. chromium, copper, nickel and phosphorous. On exposure to air, under suitable conditions, they form an adherent protective rust patina. This acts as a protective layer that, with time, causes the corrosion rate to reduce until it reaches a low terminal level, usually between 2-5 years.

Key points In dry heated interiors no special 1. precautions are necessary.

The corrosion of steel can be considered 2. as an electrochemical process.

For steel to corrode, it is necessary to 3. have the simultaneous presence of water and oxygen.

The principle factors that determine 4. the rate of corrosion of steel in air are the time of wetness and the presence of atmospheric pollution.

Three BCA-SSSS Scholarships are offered each year to eligible students - one for study at the local universities and two to study at the local polytechnics. The scholarship awarded to an university student is worth S$27,000, and the scholarship awarded to a polytechnic student is worth S$6,000. A total of 11 scholarships to five university students and six polytechnic students have been awarded to date.


Opened in 1972 and a collaboration between Golf Course Designer, Max Wexler and Course Architect, Chris Pitman, and originally designed by Frank Pennick – The Tanjong was nominated Singapore ‘s best golf course in The Asian Golf Review for three Consecutive years from 1997. In 1993, S$40 million was spent to remodel and to build a spectacular new clubhouse.

Designed for championship play from the blue tees (6,014m), the par-72 Tanjong course features natural hazards, freshwater lakes, towering trees, mounds and bunkers as well as undulating fairways with narrow landing areas. Play at the Tanjong course is a memorable experience as it is set against an alluring South China Sea backdrop and a majestic finishing at Hole #18, on its refurbished greens.

About Sentosa golf club’s tanjong course...

After a hearty buffet lunch in Sentosa Golf Club’s Grand Salon at 11:30am, the shot-gun start signal was sounded at 1:30pm. Format for play was Double Peoria for the day. Novelty prizes were given for hole-in-one, longest drive and nearest-to-pin on course challenges.

The Champion of the Tournament (a SSSS member) had his name engraved on the SSSS-Continental Challenge Trophy. In addition, attractive door gifts were contributed by supporters of the annual fund-raising golf tournament. A sumptuous sit-down dinner awaited the guests at 7:30pm in Grand Salon wherein a host of lucky-draw prizes were given away.

All participants and guests of this year’s SSSS-BCA fund raising golf event are looking forward to next year’s exciting event, and having yet another chance to spend quality time with

colleagues, partners and guests over 18-holes of challenging golf for a good cause.

GARDENS BY THE BAY

bAcKgroUnD Singapore Gardens by the Bay is the largest

garden project ever undertaken in Singapore, and a landscape project of world significance intended to raise Singapore’s profile and cement its image as the leading garden city in the east. This project is integral to the future planning of Singapore as a major global hub and business centre. The master plan takes its inspiration from the form of the orchid flower, and has an intelligent infrastructure that allows the cultivation of plants that would not otherwise grow in Singapore.

This project was won in an international design competition as part of a team led by landscape architects Grant Associates.

In order to give its members a first-hand experience of the construction of what will become one of Singapore’s iconic steel structures, Singapore Structural Steel Society’s Mr Anthony tan had organised a site visit to the gardens by the bay at Marina South (gbMS). When completed, it will feature two huge steel-glass structures to house plants and trees from all over the world.

When completed, the Cool Dry and the Cool Moist Conservatories will showcase Mediterranean, tropical and temperate annual plants and flowering species. The Cool-Dry Conservatory will explore issues related to plants and people, whilst the Cool Moist Conservatory will focus on plants and the planet.

The structure will be integrated with the façade system and shading system to minimise the overall silhouette that obstructs natural light entering the conservatory. More specifically, the envelope itself consists of a grid-shell-arch steel structure with a double glazed skin that sits directly on the grid shell.

The façade system is an integrated part of the steel arch and grid shell system and is considered as an integral component of the overall envelope.

As the main contractor for this prestigious project, Woh Hup (Pte) Ltd hosted the SSSS visitors during the site visit on 14 August 2010. The visit was arranged by Senior Technical Manager Mr Wong Keam Tong; Senior Site Manager Mr G. Gunasekaran (Guna) gave an introductory presentation about this project to the visitors.

cooL Dry gLASS DoMe (under construction)

This structure spanning north-south will consist of 16 Steel Arches and a grid-shell structure made of S355 high grade steel and finished to a high architectural quality. Glass panels will be mounted on this grid-shell. The

Arches are numbered starting from the centre, West side - W1 to W8; and on the East side - E1 to E8. The length of these arches ranges from 137.3 metres to 100.5 metres, and have a maximum height of 39 metres. The arches are designed as fixed at north base and partially fixed flexible connection at the south base. The grid-shell structure is designed as a ‘Partially Fixed Flexible’ connection at perimeter base.

The arches are fabricated and delivered to site by Yongnam Engineering & Construction Pte Ltd in segments of up to 22.5 metres length. These segments are joined and welded at site on top of a temporary support. Two numbers of nose segments for each arch, of a total weight of about 30 tonnes, are joined at the ground and hoisted up. The fabrication of the arches and the grid-shell are done to high accuracy –

maximum 8 mm variation at the 3 directions, mandated by the precision requirements for the grid-shell dome structure constructed beneath the steel arches, on which the glass panels will be mounted subsequently. The grid-shell is made of hot-finished triangular hollow sections.

The construction involves different levels of temporary Crash Deck to support the structure and accommodate the scaffolding which are used for the installation of the steel structure and glass panels. The erection sequence for the arches is symmetrical, ie. starting with E1 and W1, followed by E2/W2, E3/W3 and so on, both sides continuing equally.

Installation of the glass will begin centrally and progressively continue to the sides, in order to load the structure equally. The glass panels at the grid-shell will range in sizes from approx 1m x 2m to 2m x 3m, with a weight of up to about 400 kgs.

cooL MoiSt gLASS DoMe (base under construction)

The construction sequence for the ‘Cool Moist Glass Dome’ will be identical to that of the ‘Cool Dry Glass Dome’. The crown of the arch will be a height of 59 metres. The unique aspect though is that this dome will enclose a 39m high mountain-shaped RC structure (under construction shown in the picture, left), with a waterfall at the centre of the dome. The concrete surface of this mountain will have a Green Wall. Additionally, there will be a 31m high “Cloud Walk” plus a 13m high ‘Canopy Walk’ for the public to stroll around.

Structural steel design was done by Meinhardt (Singapore). Prof S L Chan of The Hong Kong Polytechnic University and Prof Richard Liew of NUS provided independent review on second-order buckling and recommended bolted connections at certain locations of the grid-shell to better accommodate the temperature load case.

viSUAL MocK-Up Unit (vMU)In order to ensure that the Domes are

constructed to meet stringent criteria, a mock-up structure was erected to actual size and to test the architectural finishes.

the World Steel Association (World-steel) has released its October 2010 short range outlook (SRO) for 2010 and

2011. Worldsteel forecasts that apparent steel use will increase by 13.1% to 1,272 mmt in 2010 after contracting by - 6.6% in 2009. This represents an improvement of 35 mmt over the April SRO for 2010 exceeding the pre-crisis peak of 1,222 mmt in 2007. In 2011, it is forecast that world steel demand will grow by 5.3% to reach a record 1,340 mmt.

The worldsteel Economics Committee met in Rio de Janeiro in September 2010 to discuss the October 2010 SRO.

Commenting, Daniel Novegil, Chairman of the worldsteel Economics Committee said, “Our first SRO forecast after the economic cri-sis in 2009 suggested 8.4% growth in steel de-mand in 2010. We have now revised this figure up to 13.1%. This improved out-look is due to a better than expected forecast for the de-veloped economies particu-larly the EU, NAFTA, and the CIS as well as the contin-ued strong rebound in most emerging economies. This suggests a steady and stable steel recovery, and our cur-rent forecast does not fore-see a double dip recession as feared by some.”

“Despite the better than expected forecast for 2010, we are still cautious. Steel demand in the developed economies in 2011 will still be well below the pre-cri-sis peak level. The recovery so far has been mainly driven by the inventory cycle and government stimulus packages whose effects are now fading out. But, whether consumer and corporate spending will now pick up and continue the recovery momentum is yet to be seen. Recent economic indicators are giving us mixed signals and developments in the re-maining part of this year and early next year must be watched carefully.”

China’s apparent steel use in 2010 is expect-ed to increase by 6.7% to 579 mmt after the strong increase of 24.8% in 2009. While China showed an increase of 9.2% in apparent steel use during the period of January to August in 2010, it is forecast that China’s apparent steel use growth will slow down consider-ably in the remaining part of this year due to the Chinese government’s effort to cool down the real estate sector and ongoing production control. In 2011, the growth rate will further slow to 3.5% with a weak real estate sector and the phasing out of stimulus packages.

While the forecast for China is for a fairly low growth rate compared to other countries,

Worldsteel Short Range Outlookits apparent steel use in 2011 will be 42% above 2007 level. China will account for about 45% of world apparent steel use in 2011.

India’s steel demand grew 7.5% during the crisis and is expected to grow by 8.2% and 13.6% in 2010 and 2011 respectively. With 68 mmt of apparent steel use in 2011, India will become the third largest steel using country in the world after China and the US. India’s steel use will be 32% above its 2007 level.

In the NAFTA region, the US had a 36.2% reduction in apparent steel use in 2009. Aided by stock building activities and a recovery in manufacturing, apparent steel use in the US is expected to grow by 32.9% in 2010 and then 9.4% to 86.1 mmt in 2011, bringing it back to 79.7% of the 2007 level. For NAFTA as a whole, apparent steel use will grow by 31.3%

and 8.7% in 2010 and 2011 respectively.In Central and South America, apparent

steel use recorded a -23.6% fall in 2009, but the region’s steel demand is coming back strongly thanks to recovering commodity prices, exports and renewed capital inflows. The region’s apparent steel use will grow by 28.2 % in 2010 aided by a strong rebound of 34.6% in Brazil. In 2011, the region’s appar-ent steel use will grow by 9.1% to reach 47.6 mmt, a historical high for the region and 14% higher than the 2007 level.

The EU economies had a -35.7% reduction in their apparent steel use in 2009 with Spain, Italy, and the UK especially hard hit due to the collapse of their construction sectors. The re-covery in the EU is turning out to be stronger than expected as the region’s manufacturing exports, especially Germany’s, gets a boost from the global recovery. In 2010, the region will see an increase of 18.9% in its apparent steel use on the back of inventory rebuilding and strength in the export sector. In 2011, an increase in real use is expected to drive the re-gion’s steel demand to grow by 5.7% to reach

147.4 mmt, bringing it back to 75% of the 2007 peak.

Japan, which experienced a fall of -32.3% in apparent steel use in 2009, will see its steel use increasing by 19.1% in 2010, much higher than expected, thanks to fiscal stimuli and strong export growth. But in 2011, its steel demand is expected to retreat by -1.4% due to tight fis-cal policy, strong Yen, and weakening of its major steel using sectors. This brings Japan’s apparent steel use in 2011 to 62.0 mmt, 76% of 2007 level.

The recovery in the CIS region is surpris-ingly robust. Apparent steel use in the re-gion fell -28.3% in 2009 with a fall of -43.0% in Ukraine. In 2010, apparent steel use in the CIS region is expected to grow by 26.5% and then by 11.1% in 2011. This brings the region’s

apparent steel use in 2011 to 89% of the 2007 peak.

Turkey, which experienced a -16% decline in apparent steel use in 2009, will see a strong recovery of 20.5% in 2010, followed by a further 10.7% growth in 2011 to reach 24.1 mmt, which will bring its apparent steel use back to the 2007 peak level.

The MENA region was sta-ble in 2009 despite the fall in oil prices and collapse in the construction market which was offset by an expansion-ary fiscal stance in the GCC countries, Egypt, and Iran. The region recorded a 0.4% growth in 2009 and expected to show a 5.9% and a 5.3%

growth in apparent steel use in 2010 and 2011 respectively. This will bring apparent steel use in the MENA region to 65.7 mmt, which is 17% above the 2007 level.notes:• The projections forecast by worldsteel con-

sider both real and apparent steel use. Ap-parent steel use reflects the deliveries of steel to the marketplace from the domestic steel producers as well as from importers. This differs from real steel use, which takes into account steel delivered to or drawn from inventories.

• The Short Range Outlook is provided by the worldsteel Committee on Economic Studies which meets twice a year. The Committee membership consists of chief economists from more than 40 of the worldsteel mem-ber companies. The Committee considers country and regional demand estimates to compile a global overview on apparent steel use (ASU). The Short Range Outlook is presented to the Board for their final review before publication.

APPRAISAL OF STEEL STRuCTuRESWhen existing steel buildings are

considered for change of use or alteration, or a structural survey

is required for insurance purposes or after some trauma, such as a fire, appraisal and as-sessment will be required. For more modern structures with comprehensive drawings, and design to modern standards, this should pres-ent little difficulty. This article concentrates on older structures, which will pose more chal-lenges. Expert advice should be sought from experienced engineers as the article presents some general guidance only.

Appraisal can be considered as the total process, involving investigations of the condition of an existing structure, its form of construction, its material, connections, fire resistance and robustness. Assessment is the calculation of the structure’s adequacy, based on contemporary and historical standards and based on an understanding of materials and structural behavior.

“If it ain’t broke, don’t fix it.”A structure that is clearly performing

adequately in its current condition and under current loads does not necessarily require remedial work. It should be remembered that the best attempt at a rigorous analysis and calculation of stresses will only be an approximation to what is actually happening. The following questions should be considered:

Is there evidence of overall problems • such as instability, undersize or missing members or connections, or gross distortion?Is there evidence of distress such as • excessive deflection, corrosion, distortion, cracking or fracture?Is there evidence of activity that could • produce excessive deflection or aggravate distress in the future (for example leaks to cause corrosion, exposure to aggressive chemicals or seawater, exposure to substantial dynamic or repeated loading)?Will continued use, or the proposed new • use, increase loadings and other actions on the structure above established existing levels?

the As-built StructureModern structures are hardly ever

constructed as the initial drawings may indicate, so it would be surprising to discover that an older building was in full accord with any drawings that may exist – a thorough investigation will be essential.

It’s always worthwhile however to attempt to look for the following:

Missing connectors (bolts, rivets, etc.).• Defects in cast iron and welds such as • blowholes and porosity.

While some of these items should be readily visible, problems arise with painted metalwork, and embedded or encased metalwork. In such cases it may be necessary to remove paintwork by blast cleaning (taking health and safety precautions as appropriate), to open up embedded or encased metalwork

for closer examination or to adopt non-destructive test methods. The uncovering of metalwork may be unwelcome, but is an important step in the appraisal process as the encasement itself may have encouraged water penetration and retention, and may therefore be concealing significant defects. In some cases, the expansion of corrosion products may be revealed by cracking in the encasement. The absence of cracks should not be considered definitive, as the encasement may have been replaced without addressing the internal defects.

Structural Members and connectionsCareful examination of sections to establish

sizes is needed, especially with built-up members and hollow sections. Hollow cast iron sections may have an eccentric void, so investigation of the thickness at intervals around the section (and at different levels to avoid drilling at the same level) is recommended. Several references provide dimensional data for older rolled sections.

It is important to locate any original records, and any records or subsequent investigations, alterations, remedial works etc. The general form of construction is likely to follow the type of construction common at the time the structure was completed, so reference to historical records, reports on similar buildings and reference works that describe construction types can be helpful in identifying design practice and forms of construction. Such documents may well indicate the type of material to be expected, and identify details which may require remedial work, and help identify where detailed investigation should be focused.

What Material?In structural applications, metals will

generally be grey cast iron, wrought iron, or steel. These three materials can be distinguished principally by appearance. Dating may be helpful in corroborating visual evidence, and particularly in separating wrought iron (late 1840s to 1890s) from steel (1880s to the present day). Sampling will give definitive confirmation of material; this may be essential, especially in more recent structures where there may be stainless steel, spheroidal graphite cast iron, or cast steel. Sampling must be carefully undertaken – especially if cast iron is suspected, due to its brittle behavior. Guidance is available on how and where samples should be taken.

Structural DefectsExamination should aim to identify and

record the structural condition, including:Distortions such as bowing, bulging, local • impact damage, out-of-plumb, buckling, and bolt and rivet distortions.Fractures and cracks in members and • connections (with particular attention to cast iron and welds).Corrosion•

overall Structural performanceIn addition to the adequacy of individual

members and connections to carry the self weight and externally applied loads, the structure will be required to have certain levels of robustness against disproportionate collapse. As tying requirements are relatively modern, very old structures will not have made explicit provision for this design issue. In some cases, the form of construction may provide adequate tying with no further work – in others, some strengthening work may be necessary. More modern performance requirements also include the need for fire protection, where a range of solutions are possible from intumescent coatings to encasement.

remedial WorkA whole range of solutions are possible to

repair, replace, reinforce or relieve existing members. With older buildings of historical interest, it may be that the visual appearance of the remedial measures or the impact on the existing structure is of critical importance to the owners or regulators that need to be discussed at an early stage of development as minimal intervention may be demanded.

Key pointsIt is important to understand the charac-• teristics and behavior of any structural material or form of construction as a pre-requisite to the appraisal process.The properties of cast and wrought iron • and steel are predictable, and permit structures using these materials to be re-used, adapted and upgraded.Wrought iron and steel are ductile • materials. Cast iron is relatively brittle and weaker in tension than compression.The historical aspects of the use of these • materials, their quality of manufacture and installation, and the design methods existing at the time, are all important considerations in the appraisal process.Material testing may be required to • provide more quantitative information.Load testing may be carried out in • extreme situations.Strengthening or upgrading of the existing • structure often requires attachments formed by welding, bolting or clamping, or in some cases by composite action with other materials.Fire protection can be achieved by • intumescent coatings, or encasement.
