This research aims to develop a new displacement based (DB) method for regions of lower seismicity, using 'Displacement Controlled' phenomenon, to assess the risk of collapse and seismic performance of buildings. The project will investigate the system behaviour of buildings in Australia that are laterally supported by lightly reinforced concrete geometric walls, including both torsional and wall floor interaction effects. The new DB method could allow buildings in regions of lower seismicity to be designed for robustness, gravity and wind loading and then checked using displacement principles for seismic compliance, which will dramatically simplify and improve the current seismic design process.Read moreRead less

An earthquake shaking table to investigate soil-structure interactions: This project aims to develop Australia's most advanced earthquake shaking table. Earthquakes are a problem of great significance to Australia. Infrastructure in civil, transport, mining and energy sectors may be at an unacceptable risk of damage under earthquake loading as current design practices do not account for the interaction between infrastructure and the ground under such loading. The shaking table will simulate earthquakes and enable controlled testing of three-tonne models of foundation and soil-structure interaction systems typical of Australia's infrastructure. The discoveries made are expected to be integral to the modernisation of Australia's seismic design standards so that earthquake-induced damage and risk exposure can be minimised.Read moreRead less
