Flagship Leader (2018): Ken Elwood (k.elwood@auckland.ac.nz )

Flagship Deputy:  David Johnston

Flagship Summary

This flagship will result in the development and validation of procedures to forecast the socio-economic impacts of building demolitions and retrofits that are legislated to occur within the coming decade.  Improved assessment guidance will mitigate conservative seismic assessments that result in unnecessary demolition of existing buildings, including the country’s built heritage, enabling economically-viable policy solutions. Proven cost-effective and architecturally-appropriate earthquake strengthening solutions will be developed and communicated to structural engineers nationwide so that results can be immediately implemented. Consideration will be given to the range of existing buildings posing a risk in New Zealand’s cities, not just those classified as earthquake-prone by legislation. 

The key thrust areas are:

  1. Development of validated methodologies for detailed assessment and improvement of earthquake-vulnerable buildings such as unreinforced masonry and reinforced concrete buildings.  Where possible, validation may be achieved via field testing in buildings scheduled for demolition.
  2. Development of methodologies for economic assessment of options for addressing earthquake-vulnerable buildings, namely: mitigation, demolition, or no action.
  3. Understanding the development of policy and initiatives regarding earthquake-vulnerable buildings, including understanding societal involvement and expectations in such policy.

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.
