Missed the 2019 Concrete NZ Learned Society Seminars? Try the Webinar

The wreckage from COVID-19’s slipstream includes the disruption of the Learned Society’s seminar programme – the first event won’t take place until later this year.

But members may be interested in the pair of webinars we have created from two seminars held last year – particularly if you weren’t able to make those events.

If we can take anything ‘positive’ from the virus, it’s the proof that webinars are an effective way of reaching people – even in extraordinary circumstances.

The two webinars are Strut & Tie (held in September 2019), and Assessment of Existing Concrete Buildings using the Revised C5 Guidelines (held in June 2019).

Always a well-attended seminar, the Strut & Tie method of analysis and design is a unified approach that considers all load effects (M, N, V, T) simultaneously. It has evolved as one of the most useful design methods for shear critical structures. 

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. 

Though the Strut & Tie procedure is detailed within NZS 3101, it has not (until recently) been widely covered during structural engineering courses.

The seminar (webinar) was (is) presented by Des Bull (a Technical Director of Holmes Consulting Group LP), and Rick Henry (senior lecturer in the Department of Civil and Environmental Engineering at the University of Auckland).

The Assessment of Existing Concrete Buildings using the Revised C5 Guidelines seminar explores a simpler and more comprehensive means of assessing existing concrete buildings prevalent throughout New Zealand. 

The revised Guidelines were released in late 2018 and was developed through the combination of international guidance and local research. 

The seminar/webinar was (is) presented by Professor Ken Elwood (the MBIE Chair in Earthquake Engineering and Director of QuakeCoRE: New Zealand’s Centre of Research Excellence for Earthquake Resilience), and Nicholas Brooke, a consulting engineer and Principal at Compusoft Engineering. Nicholas is also the current president of the Concrete Society.


  • The Strut & Tie webinar comprises four sessions priced at $160+GST.
  • The C5 Guidelines webinar comprises six sessions priced at $240+GST.

Once purchased, they are available to view for seven days.

The webinars must be viewed on-line – they can’t be downloaded – and they must be accessed before the seven-day window expires. They can, however, be viewed session-by-session at different times (to suit viewers’ schedules) within the seven-day window.

The webinars can be accessed here.
