Seismic assessment of reinforced concrete walls in Australia
This project assessed the performance of reinforced concrete walls in response to rare and very rare earthquakes. This research firstly reassessed the seismic activities for 500 year and 2500 return period earthquakes in Australia. Using the results of earthquake hazard demand, the performance of existing reinforced concrete walls was assessed in response to these events. Cost effective changes or detailing provisions were recommended from the results.

This PhD assessed the performance of reinforced concrete walls in response to rare and very rare earthquakes. This research analysed both rectangular and C-shaped concrete walls to develop a secondary cracking model to predict the potential of cracks forming in these types of walls. It was found that the direction of loading and the mode of bending were particularly important for the seismic performance of these sorts of walls.

This project was completed in September 2017.
