Collapse assessment of reinforced concrete buildings in regions of lower seismicity. 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 interacti ....Collapse assessment of reinforced concrete buildings in regions of lower seismicity. 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
Retrofitted brick masonry buildings - are they reliable over the long term? The aim of this project is to investigate the long-term reliability of a new earthquake strengthening technique for brick buildings. The technique involves the use of fibre reinforced polymer (FRP) strips as reinforcement for brick walls and has been shown to give substantial instantaneous strength increases. However, no research has been undertaken to ensure that the improved strength is sustained over the remaining lif ....Retrofitted brick masonry buildings - are they reliable over the long term? The aim of this project is to investigate the long-term reliability of a new earthquake strengthening technique for brick buildings. The technique involves the use of fibre reinforced polymer (FRP) strips as reinforcement for brick walls and has been shown to give substantial instantaneous strength increases. However, no research has been undertaken to ensure that the improved strength is sustained over the remaining life of the building. The only related research involves reinforced concrete which suggests that a reduction of at least 33 per cent could be expected. Hence, this project will quantify the long-term strength of FRP reinforced brickwork to enable engineers to safely apply this new cost-effective retrofit technique.Read moreRead less
Improved analysis techniques for seismic assessment of unreinforced masonry buildings with flexible floor/roof diaphragms. A major international collaboration between researchers in Australia, New Zealand and Italy is underway to develop a method for structural engineers to determine which masonry buildings post a significant hazard to the public in the event of an earthquake such as that which struck the city of Christchurch.
Development of efficient, robust and architecturally-flexible structural systems using innovative blind-bolted connections. The aim of the proposed project is to develop structural systems that have sufficient stiffness, strength, and ductility to withstand code-specified loads and that will be competitive in the marketplace. The development of demonstrable cost-effective structural systems is essential if these types of systems are to be widely adopted in practice, thus allowing Australian manu ....Development of efficient, robust and architecturally-flexible structural systems using innovative blind-bolted connections. The aim of the proposed project is to develop structural systems that have sufficient stiffness, strength, and ductility to withstand code-specified loads and that will be competitive in the marketplace. The development of demonstrable cost-effective structural systems is essential if these types of systems are to be widely adopted in practice, thus allowing Australian manufacturers of blind bolts and steel tubes to achieve a greater market share.Read moreRead less
Numerical and experimental study of pounding damage of adjacent bridge structures to spatially varying earthquake ground motions. Bridge damage in an earthquake prevents rescue personnel and equipment from quick access to the affected area. Repairing or replacing a damaged bridge and the increased commuting time after the earthquake may have a significant impact on the economy and life of the general public. This project will develop techniques for earthquake-resistant bridge design.
Seismic performance of precast concrete buildings for lower seismic regions. This project aims to develop a displacement-based method of assessing precast concrete buildings in regions of lower seismicity for risk of collapse and seismic performance. The project will investigate the system behaviour and vulnerability of buildings laterally supported by precast concrete geometric walls, which are currently poorly understood but dominate Australian construction. The modelling produced is expected ....Seismic performance of precast concrete buildings for lower seismic regions. This project aims to develop a displacement-based method of assessing precast concrete buildings in regions of lower seismicity for risk of collapse and seismic performance. The project will investigate the system behaviour and vulnerability of buildings laterally supported by precast concrete geometric walls, which are currently poorly understood but dominate Australian construction. The modelling produced is expected to allow such buildings to be simply checked for seismic compliance using displacement principles, rather than the more complex force based methods with direct benefits for building costs and community safety.Read moreRead less
