Opportunity
The vast majority of earthquake-related deaths occur due to building collapse, and therefore the most direct way to minimise fatalities and injuries is to first identify then remediate or demolish the nation’s earthquake-prone building stock. In March 2014, the Earthquake-prone Buildings Bill passed its first reading in Parliament, with the express purpose to establish a nationally consistent approach to addressing the risk posed by earthquake-prone buildings (EPB). Considering the number of EPB throughout NZ, the high costs of remediation, and the heritage value of many EPB, this legislation has broad implications for the NZ economy, owners of earthquake-prone buildings, and all members of the community.
There is a window of opportunity for QuakeCoRE researchers to significantly inform this national debate with leading-edge multi-disciplinary research that seeks a balance between heritage, safety, and economics. This Flagship will pursue three interconnected families of research needs all linked by case studies. Conventional economic decision-support tools will be advanced in order to address the current failure to recognise the complexities of low-frequency high-consequence events with community-wide impacts and the value of cultural heritage. Drawing upon multidisciplinary community datasets, the scope of the EPB ‘problem’ in NZ will be quantified rigorously for the first time. This ‘baseline’ will then be used in the development of robust multi-scale models for prototypical building systems, providing an improved understanding of their seismic response characteristics and reduce current excessively conservative structural assessments which may lead to unnecessary demolition or overly-conservative remediation strategies. Finally, QuakeCoRE will build on its proven track record related to the assessment and mitigation of URM buildings to develop cost-effective and aesthetically-acceptable methods for seismic strengthening of pre-1970’s concrete structures and other non-ductile buildings. These efforts will be linked using community case studies for Auckland and Wanganui.
