The objective of this research is to develop strategies to mitigate damage, injury and business disruption associated with the earthquakes in the most vulnerable buildings of Australia’s cities.
The hazard earthquakes pose has only been recognised in the design of Australian buildings since 1995. This failure has resulted in the presence of many buildings that represent a high risk to property, life and economic activity. These buildings also contribute to most of the post-disaster emergency management logistics and community recovery needs following major earthquakes. This vulnerability was in evidence in the Newcastle earthquake of 1989, the Kalgoorlie earthquake of 2010 and with similar building types in the Christchurch earthquakes in 2010 and 2011. With an overall building replacement rate of two percent nationally, the legacy of vulnerable building persists in all cities and predominates in most business districts of lower growth regional centres.
This research project is drawing upon and extending existing research and capability within both academia and government to develop information that will inform policy, business and private individuals on their decisions concerning reducing vulnerability. It is also drawing upon New Zealand initiatives that make use of local planning as an instrument for effecting mitigation.
The project’s scope includes all typical building construction types in Australia as specified in the Australian Standard for Earthquake Loading AS 1170.4. It excludes special construction such as power plants, offshore structures and other industrial/manufacturing structures.
While the focus of this project is on buildings, many of the project outputs will also be relevant for other infrastructure such as bridges, roads and ports, while at the same time complementing other CRC projects for severe wind and flood.
To achieve this, the project is sifting through the data that is available from the Christchurch experience to establish what earthquake retrofit techniques worked and what did not as a starting point in developing a menu of economically feasible seismic retrofit techniques that could be used in Australian cities.
Other research studies conducted have investigated the effects of local site conditions on ground shaking, assessed buckling and instability failures of lightly reinforced concrete walls, and reviewed the economic loss modelling of earthquake damaged buildings, among others.
This information will be fed into a decision support tool being developed that will be used by end-users to develop consistent national policies for the application of seismic design of new buildings and retrofit of existing buildings.
In the past three years 48 research papers have been published including 20 in journals and 28 at national and international conferences.
