Following the devastating Christchurch earthquake of February 2011, Peter McBean of Wallbridge Gilber Aztec, spent two weeks within the city, providing structural engineering advice to the Australian USAR response team whilst experiencing over 200 after-shocks. For this work he was awarded the Humanitarian Overseas Service Medal by the Australian Government.

With over 30 years experience as a consulting structural engineer, Peter has fostered an expert capability in structural dynamics and earthquake engineering. He is the current National President for the Australian Earthquake Engineering Society and also a member of Standards Australia Code Committee BD-006-11,responsible for Earthquake Actions in Australia, AS1170.4 and the BD-002 Code Committee responsible for AS3600.

At a CIBSE SA event last week, Peter outlining past earthquake recordings and magnitude, the fault type of earthquake reactions, the probability event cycle and design parameters. He also shared some examples of buildings that survived the Christchurch catastrophe, those that did not and the reasons why.

The presenation included examples of post disaster design, that ensure buildings maintain their operational facilities, including building services installations. The new Adelaide Royal Hospital has been considered for such provisions; being the only such hospital in Australia that can meet such demanding criteria.

The event was kindly sposored by WGA.
