FOUR FROM FOUR!Congratulations to Nicholas Brooke and Ken Elwood for the consistently excellent feedback they received for their C5 Guidelines seminar series.
The last of the four seminars was presented in Auckland in July. The series explored the revised Part C5 of the Engineering Assessment Guidelines which now provide a simpler and more comprehensive means of assessing existing concrete buildings common throughout New Zealand.
This final seminar was also recorded – with a view to offering it as a webinar and, similarly, all future seminars will be recorded. The availability of such webinars will aid the Society’s ability to deliver seminar content to members in regions beyond the main centres.
How best to make the webinars available is to be discussed at the next Council meeting. We will keep readers updated with developments.
The Society extends its deep appreciation to Nicholas and Ken – sterling stuff gentlemen!
REVISITING THE STRUT & TIE SEMINARS
The popular Strut & Tie seminars – last held in May 2014 – are being re-run but have received a major refresh with plenty of new content.
As was the case in 2014, the series of four seminars will again be presented by Des Bull and Rick Henry.
The Strut & Tie method of analysis and design is a unified approach that considers all load effects (M, N, V, T) simultaneously and has evolved as one of the most useful design methods for shear critical structures and the regions of concrete structures where complex interactions occur.
The method relies on a first-principles approach to explain how forces are transmitted through reinforced concrete and is particularly effective when trying to explain the complex actions occurring in diaphragms, deep beams, prestressed members, and members with penetrations.
The procedure also allows a consideration of the likely pattern of cracking and is particularly effective as an investigative tool when trying to explain post-earthquake observations. The procedure is detailed within NZS 3101 but until recently has not been widely taught to training structural engineers.
This seminar covers the basic theory of strut and tie modelling and how it can be used to design complex regions of concrete structures. It also explores concepts of establishing simple, reliable and practical strut and tie models for different types of concrete members.

RED BOOK IN FIJISome 60 Fijian delegates attended the CNZ – Learned Society’s Red Book Shear Walls Seminar held recently in Fiji.
This seminar was first presented in New Zealand in July last year and was then attended by Nathan Kirk – the President of the Fiji Institute of Engineers (FIE) – a regular visitor to our events. After the seminar he suggested it would be of great interest to engineers in Fiji.
So CNZ member Nicholas Brooke and colleague Tony Stuart went to Fiji to present the seminar. “There was a great turnout,” says Nic, “and we believe these island visits will become a regular occurrence in future. From the Learned Society’s perspective, it was very satisfying to be able to assist FIE, a relatively new organisation.”
Among other subjects, the seminar explores concepts of seismic design, methods of seismic analysis, structural analysis and design actions for the building, and design of coupled walls and coupling beams.

SpeakersDes Bull is a Technical Director of Holmes Consulting Group LP. His duties involve the development of structural engineering services for the company, with an emphasis on concrete structures and the performance of concrete materials in a variety of environments and in-service conditions. He has served on the Technical Committees for NZS 3101: Concrete Structures and NZS 1170.5: Earthquake Loads.
Rick Henry is a senior lecturer in the Department of Civil and Environmental Engineering at the University of Auckland where he teaches the design of concrete structures, including strut and tie methods. His research interests include the seismic design and assessment of reinforced concrete structures and in particular precast concrete construction. He has served as a member of the technical committee for the NZ Concrete Structures Standard, NZS 3101:2006.
The Concrete NZ – Learned Society acknowledges the support of Holmes Consulting Group and the University of Auckland for making the series possible.
CLICK FOR REGISTRATION
For those who’ve not yet registered for October’s Concrete Conference in Dunedin, note that the registration portal on the Conference website is now ‘live’, accelerating the process considerably.
Early bird registration for the conference expires on September 20, and to secure attendance (and accommodation) delegates should register as soon as possible.
The Conference is being held in Dunedin for the first time and anecdotal evidence suggests many delegates will also use the opportunity to explore one of the country’s most majestic regions. Its legendary vineyards seem to hold a particular fascination for many…
A highlight of the extra mural activities will be the canoe race between students from a number of the country’s tertiary institutions. Students from the universities of Auckland and Canterbury have already entered, and others have expressed interest.
However ‘hot’ the quality of the vessels and the performance of the oarsmen, one thing is guaranteed: the crew of any canoe not remaining afloat will receive a chilly dipping.

CALL FOR ABSTRACTS Next year sees the International Association for Bridge and Structural Engineering (IABSE) Congress convene in Christchurch (2 – 4 September), and organisers are calling for abstracts of proposed papers.
This Congress’s title is Resilient Technologies for Sustainable Infrastructures.
Founded in 1929 and based in Zurich, Switzerland, IABSE has members in 100 countries. It deals with all aspects of structural engineering: the science and art of planning, design, construction, operation, monitoring and inspection, maintenance, rehabilitation and preservation, demolition and dismantling of structures, taking into consideration technical, economic, environmental, aesthetic and social aspects.
Some 400-500 delegates are expected to attend.
