Organised around the theme “Concrete: 21st Centural Superhero”, the 2009 fib symposium was held in London, UK, from 22 to 24 June 2009. This was the 11th such symposium since fib's creation in 1998. With 370 delegates in attendance representing 49 countries, and 288 accepted papers, the event was a clear success despite the current worldwide financial crisis. At the opening ceremony on Monday morning delegates were greeted by Steve Denton, head of the fib National Member Group in the UK. He expressed the organisers’ pleasure at the number of registered delegates, especially considering the continuing economic troubles around the globe. He thanked the event’s co- organiser Japanese Concrete Institute (JCI) and extended a special welcome to the many engineers and experts from Japan, including keynote speaker Koji Sakai. He remarked that despite these uncertain times, the theme of the symposium was still relevant, and indeed the solutions to long-term challenges are often engi- neering solutions. Gordon Clark, co-chair of the Technical Committee, commented on the impor- tance of concrete in the world today: concrete is used more than any other man- made material, and the only other material used more than concrete is water.

Michael Fardis gave the fib President’sWelcome address, in which he stressed thespecial historical relationship between fiband London: the city has long been aninternational centre of know-how andexpertise, and was the venue for severalCEB plenary sessions and FIP congressesand symposia over the past decades.

He then had the pleasure of presenting acertificate of Honorary Membership toformer fib Secretary General RüdigerTewes, and Medals of Merit to MarcoMenegotto and Eduardo C. Carvalho (seefull report on page 155).

The morning’s keynote presentations weregiven by Dr. Ahmad Rahimian, Dr. KojiSakai, and Prof. Odd E. Gjørv. Dr.Rahimian’s presentation on the “Nahkeelsuper tall tower” focused on the designchallenges of this record-breaking towerunder construction in Dubai, which willreach a height of over 1 km. Dr. Sakaidiscussed the need for an environmentalrevolution in concrete technology, stressingin particular the CO2 emissions fromconcrete production, and scenarios toreduce these emissions. Prof. Gjørv’sspeech addressed durability and servicelife, particularly how they relate to

construction issues and quality control.

Over 30 technical sessions were then heldin parallel throughout the three-day event,on the themes of sustainability, durability,materials, structure and construction, anddesign andanalysis. The pro-ceedings, inclu-ding all papers infull as well as thekeynote presen-tations, will beavailable for pur-chase from theConcrete Society,on behalf of the the fib UK Group; formore information contact Richard Day,[email protected].

Also taking place during the symposiumwas the award ceremony for the fibDiplomas to Younger Engineers, awardedthis year to Dr. Ana Maria Ruiz-Teran andMr. Chris Hendy (see page 157).

Social events and networking oppor-tunities were an integral part of the event.The welcome reception at the BarbicanCentre, the festive symposium banquet onTuesday evening, and the centrally locatedexhibition area gave delegates ampleoccasions to meet, network and socialisewith old and new friends and colleagues.

The symposium concluded with a keynotepresentation by Joost Walraven, fibHonoray President, FIP medallist and SAG5 Chairman (and honorary doctor; seepage 158), on the role of engineers today.He focused in particular on the importanceof finding new, “out of the box” solutionsto today’s sustainability problems.

The 2009 fib Medals of Merit wererecently awarded to Eduardo C. Carvalho,Portugal, and Marco Menegotto, Italy, inrecognition of their outstanding contri-butions to the field of structural concrete,and to fib. The medals were presented tothe two awardees on 22 June 2009 by fibPresident Michael N. Fardis, during theopening session of the recent fibsymposium held in London, UK.

Born in 1951, EEdduuaarrddoo CC.. CCaarrvvaallhhoo hasplayed an important role in the work ofCEB and fib for over two decades,particularly in the area of seismic design.He was part of the CEB Task Group that

drafted the Model Code for SeismicDesign of Concrete Structures in the early1980s, which was published as CEBBulletin 165 and was a precursor toEurocode 8, “Design of Structures forEarthquake Resistance”. As Secretary ofCEN/TC250/SC8 from the outset until2005 he played a central role in thedevelopment of Eurocode 8 (EC8) as aprovisional Standard (ENV) and than as aEuropean Standard (EN). As the Chairmanof CEN/TC250/SC8 since 2005, he over-sees the implementation of Eurocode 8and leads its maintenance and the workfor its future development.

The activities of Special ActivityGroup 2 on short courses are in theprocess of being developed andexpanded; a report on these new courseswill be published in the December issue offib-news. A new Special Activity Group(SAG) on assessment of concretestructures was approved; it is planned toinitiate it with a workshop this autumn.

During the General Assembly, newmember Cyprus and returning memberAustralia were welcomed. HonoraryMembership for Rüdiger Tewes andHonorary Presidency for Hans RudolfGanz were unanimously approved.

Furthermore, a number of fibCommissions held meetings in andaround London before, during and afterthe symposium. SAG 5 "New ModelCode" had an important meeting tofinalise the draft that will be submitted tothe fib General Assembly for approval in2010. Commission 6 and PCI heldanother successful joint workshop inwhich they continued the comparison oftheir respective methods. The results ofthis comparison are to be presented nextyear at the fib Congress.

He has been a member of several CEB andfib administrative bodies, and is currentlymember of the fib Technical Council, Headof the Portuguese National Delegation,and member of fib Commission 7, Seismicdesign, and of Task Group 7.6, Criticalcomparison of major seismic design codesfor buildings.

Dr. Carvalho is the former Head of Centrefor Earthquake Engineering at theLaboratório Nacional de Engenharia Civil(LNEC), and has been a partner in theconsulting office GAPRES (Gabinete deProjectos, Engenharia e Serviços) SA since1981. Through this consultancy he beeninvolved in the design and construction ofa many structures in Portugal, such as theExhibition Pavilions for EXPO 98 in Lisbonand a number of hotels as well asresidential and commercial buildlings.

It is noteworthy that the first edition of thefib Diplomas for Younger Engineerssponsored was by the Portuguese nationalgroup and presented by Eduardo Carvalhoin 2001. The second edition of the awardin 2003 was then sponsored by AICAP

(Associazione Italiana Calcestruzzo Armatoe Precompresso) and presented by theItalian delegation, including MarcoMenegotto. This bienniel traditioncontinues, with the fifth edition of theaward presented this year during theLondon symposium (see page 157).

Born in 1940, MMaarrccoo MMeenneeggoottttoo isProfessor of Structural Engineering atUniversita di Roma la Sapienza since 1980.He has been strongly involved in both thetechnical and administrative work CEB, FIPand fib for over 30 years. He has worked ina number of CEB and fib Commissions andTask Groups, including “Structural Analy-sis”, “Design by testing”, and “Bucklingand instability” which produced CEBBulletin 155.

Among his many notable achievements,Prof. Menegotto is particularly well knownfor his contribution to the modelling ofreinforcing steel under cyclic loading, firstpublished in 1973 in the conferenceproceedings of the IABSE Lisbonsymposium, and still widely used today.

He has also carried out assessment, repair,and upgrading work for a number ofimportant structures in Italy and aroundthe world, and was a UNESCO consultantfor the stability assessment of heritageconstructions.

Furthermore he has been involved in thedesign and construction of a number ofstructures around the world, particularlyprecast, including the church built over theruins of the house of Saint Peter inCapernaum, Israel, as well as a number ofbridges and residential buildings.

Currently he chairs fib Commission 6,Prefabrication, is a member of SpecialActivity Group 5, New Model Code,member of the Technical Council, andHead of the Italian National Delegation. Inaddition he is Vice President of the ItalianAssociation for Structural Concrete and ofthe Italian Association for Consolidation

and Upgrading of Constructions.

Both Prof. Menegotto and Dr. Carvalhoremarked on their honour and surprise atbeing selected as an fib medallist, andgraciously noted that they felt they havereceived much more from the fib commu-nity than they have contributed to it.

The next fib Medals of Merit will beawarded in 2011 in Prague. In 2010 theFreyssinet Medal will be presented to oneor two individuals during the WashingtonDC Congress, in recognition of theiroutstanding technical contributions in thefield of structural concrete.

Heinz Isler, structural engineer andFreyssinet medalist, passed away on 20 June 2009 at the age of 82.

Born in 1926 in Zollikon, near Zurich,Heinz Isler founded his own engineeringoffice soon after earning a degree in civilengineering from the ETH Zurich in 1950.He specialised in the development ofexperimental methods and modellingtechniques to design and create shellstructures with “free” geometry; at thefirst congress of the InternationalAssociation for Shell Structures (IASS) in1959 he presented his methods in a shortpaper entitled “New shapes for shells”.

During the next decades he used hismethods to design and build numerousconcrete shell structures, includingparking structures, industrial facilities,garden centres, petrol stations and anopen-air theatre. Over the years Heinz Islerbuilt over 1400 shell structures and wasgenerally involved in all phases of theirdesign and construction, including thedefinition of the geometrical shape, modeltesting, structural dimensioning, construc-tion methods, site supervision, andinspection and monitoring of the shells’performance during service life.

Isler’s work has been widely recognized bythe engineering community. He wasawarded various prizes and distinctions,among them an honorary doctorate fromthe ETH Zurich. He lectured at a numberof universities, including Darmstadt,Karlsruhe, Berlin and Princeton. The

Universities of Princeton and Stuttgartorganized traveling exhibitions of his workaimed at students, practicing engineersand architects. Professor Billington’s “Artof Structural Design: A Swiss Legacy”made his concrete shells and the drivingforces behind them accessible to a wideraudience.

In 2006 fib awarded him the Freyssinetmedal, in recognition of his outstandingtechnical contributions in the field ofstructural concrete.

The work of Heinz Isler is part of thelegacy of the great Swiss engineers likeGrubenmann, Köchlin, Ammann, Maillartand Menn. Like them, he regardedstructures as a whole with respect to theirscientific, social and symbolic compo-nents. And like the old master builders,who were simultaneously specialists andgeneralists, he oversaw the conceptualdesign, form-finding process, model tests,structural analysis, detailing, constructionprocedure, site supervision and long-termmonitoring of serviceability.

Isler’s concrete shells stand out asremarkable examples of structural art. Hisapproach to structures assumed anunderstanding of form according to itsorigin, essence, features and scope, inrelation to science and art, nature andmind, space and time. A true tribute to hiswork, beyond admiring and exhibiting hismagnificent shell structures, will be tounderstand his ideals, pass them on to ourengineering students, and apply them tothe built environment.

Peter Marti also plays an active role inprofessional associations and technicalcommittees, including the ACI-ASCE JointCommittee on "Shear and Torsion", theSwiss structural concrete code committeeSIA 162, and the Swiss Society ofEngineers and Architects (SIA). In fib hewas chair of Commission 4 "Modelling ofStructural Behaviour and Design" andmember of the fib Steering Committeefrom 1998 to 2006, and is currentlymember of the Technical Council.

Furthermore he was one of foundermembers and the first president of theSwiss Society for the Art of CivilEngineering, dedicated to conserving thelegacy of structural engineering andpromoting the engineering profession.

We cordially congratulate Peter Marti onhis 60th birthday and wish him continuedsuccess, further challenges, as well assome (more) time for leisure.

Álvaro García Meseguer, long-time andhighly valued member of fib and itspredecessor CEB, passed away on 27 June2009.

His involvement in CEB began in 1961,when, upon the death of Eduardo Torroja,he became Head of the Spanish Group.Shortly thereafter, in 1964, one of hismajor contributions to CEB was releasedwhen the first edition of CEB Recommen-dations was published under his direction.

In the 1970s he was Chairman of theCommission on Notation-Terminology, andunder his chairmanship the new CEB-ACIInternational Unified Notation system wasapproved. During this time he was alsoChairman of the CEB-CIB-FIP-RILEMWorking Group on statistical verification ofconcrete quality, an active member of theWorking Group which authored themanual on “Bending and Compression”,and co-Technical Director of CEB in thearea of “Deformation – instability –plasticity”. In 1977 he played a major rolein the organisation of the 19th CEBGeneral Assembly in Granada, duringwhich the first CEB-FIP Model Code wasapproved.

His strong involvement in the associationcontinued into the 80s and 90s asChairman of the working groupresponsible for several CEB Bulletins onquality control and quality assurance ofconcrete structures, and then as memberof the CEB Administrative Council and theCEB Advisory Committee for several terms.

In addition, he continued as Head of theSpanish National Group until the CEB-FIPmerger in 1998, especially contributing tothe merging process of the Spanishbranches of CEB and FIP, giving birth tothe Spanish Association of StructuralConcrete (ACHE), of which he was vice-president in 1998 and 1999.

Honorary fib membership for ÁlvaroGarcía Meseguer was unanimouslyapproved by the fib General Assembly in2008, in recognition of these invaluablecontributions to the work of CEB and fib.

Álvaro was an uncommon engineer.Author of several books on linguistics, hehad a particularly clear and humanisticvision of engineering and society, payingspecial attention to language as, concep-tually, both a vehicle and a bridge whichconnect technicians and users. He will liveon in the hearts of all who knew him.
