Seismic attenuation of structures through use of magnetorheological dampers. This project aims to improve understanding of the attenuating characteristics of the co-flowing of magnetised solid particles and fluid in a conduit subject to seismic waves generated by rapid ground movement. The distribution of magnetised solid particles in fluid plays an important role in the design of large-scale magnetorhelogical dampers for seismic conditions.

This project aims to improve understanding of the attenuating characteristics of the co-flowing of magnetised solid particles and fluid in a conduit subject to seismic waves generated by rapid ground movement. The distribution of magnetised solid particles in fluid plays an important role in the design of large-scale magnetorhelogical dampers for seismic conditions. These dampers promote the protection of historical structures and eliminate costly rebuilding of architectural structures. The project plans to perform experimental and numerical investigations to develop robust and accurate predictive models to improve understanding of the seismic attenuation of next-generation magnetorhelogical dampers, prevalent in semi-active control devices, and of the ability of such devices to suppress elevated structural vibrations.Read moreRead less
Dynamic soil structure interaction. The aim of this project is to undertake a study of an important class of geotechnical problems in which systems composed of soil, structure and pore water are subjected to dynamic or impact loading. The outcomes will include safer and more efficient methods for designing geotechnical structures subjected to dynamic loading.

Development of sandwich structures to mitigate blast and impact loading. Innovative sandwich structures with Prismatic Hexagonal-like form and polymeric foam material are proposed in this project and should lead to better designs for structure and personnel protection. Critical civil infrastructure such as government buildings might be subjected to severe blast/impact loads during their lifetime, which may lead to catastrophic consequences. Therefore, protective techniques are desired to increas ....Development of sandwich structures to mitigate blast and impact loading. Innovative sandwich structures with Prismatic Hexagonal-like form and polymeric foam material are proposed in this project and should lead to better designs for structure and personnel protection. Critical civil infrastructure such as government buildings might be subjected to severe blast/impact loads during their lifetime, which may lead to catastrophic consequences. Therefore, protective techniques are desired to increase the resistance capacity of critical structures against blast/impact loads. The expected outcome is to develop an innovative sandwich structure with new structural forms to mitigate blast/impact loads for better structure and personnel protections.Read moreRead less
Multifunctional Structural Panels for Next-generation Infrastructure. This project aims to develop a multifunctional prefabricated structural panel for current and future infrastructure applications for both land and offshore environments. Prefabrication enables enhanced product control as well as the ability to rapidly construct whole structures or their components.

This project aims to develop a multifunctional prefabricated structural panel for current and future infrastructure applications for both land and offshore environments. Prefabrication enables enhanced product control as well as the ability to rapidly construct whole structures or their components. The panels utilise an inner lightweight foam and fibre-reinforced polymer (FRP) composite core with strong outer panels made from FRP sheets and high-strength concrete. The expected outcomes include experimental and numerical validation of the system, that will give designers and asset owners the confidence to adopt this new panel. The panel system presents an upward step change in construction technology and built infrastructure performance.Read moreRead less
Study of Blast Resistance Capacity of Basalt Fibre Strengthened Structures. This project plans to investigate the dynamic response of basalt fibre reinforced polymer (BFRP) reinforced structures against blast loading. Critical infrastructures such as embassy buildings, high-rise building, bridges and defence facilities are intensively targeted by increasing terrorist activities or accidental explosions. BFRP is a promising material for such structures because it is cheaper than carbon fibre and ....Study of Blast Resistance Capacity of Basalt Fibre Strengthened Structures. This project plans to investigate the dynamic response of basalt fibre reinforced polymer (BFRP) reinforced structures against blast loading. Critical infrastructures such as embassy buildings, high-rise building, bridges and defence facilities are intensively targeted by increasing terrorist activities or accidental explosions. BFRP is a promising material for such structures because it is cheaper than carbon fibre and has better physico-mechanical properties than glass fibre. However, there has been very limited study of the effectiveness of BFRP strengthening on structure blast-loading resistant capacities. This project aims to perform numerical and experimental studies to support the development of BFRP applications in strengthening structures against blast loads.Read moreRead less
Rational lateral-bracing design for steel-framed domestic structures. For the 150,000 new Australian houses built annually to remain safe, despite expected increases in structural loading due to climate change, rational design approaches are desperately needed. This project will provide the industry with the necessary tools to develop optimised and innovative solutions to brace houses for extreme events and yet maintain affordability.
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

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

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
