This project aims to develop innovative metaconcrete for structural protection by utilising the concept of phononic crystals and metamaterials which has been recently developed by physicists. Traditional construction materials are used in new structural forms to mitigate dynamic loading effects by exploiting the unique characteristics of the proposed metaconcrete. Theoretical, numerical and experimental methods will be used to derive the best performing metaconcrete and verify its static and dynamic load resistant capacities. The expected outcomes of the project will lead to innovative extreme-loading resistant designs and provide significant benefit to the Australian construction industry, general public and economy.Read moreRead less
Improved seismic resilience against life-safety hazard of masonry buildings. This project aims to develop a cost-effective technique to mitigate the safety risk posed by the many unreinforced brick masonry parapets and walls which are vulnerable to seismic shock. Every Australian city has many streets lined with older unreinforced brick masonry buildings (now cafes, pubs, boutique shops) which feature parapets. The project will provide benefits to society by reducing the potential for parapet co ....Improved seismic resilience against life-safety hazard of masonry buildings. This project aims to develop a cost-effective technique to mitigate the safety risk posed by the many unreinforced brick masonry parapets and walls which are vulnerable to seismic shock. Every Australian city has many streets lined with older unreinforced brick masonry buildings (now cafes, pubs, boutique shops) which feature parapets. The project will provide benefits to society by reducing the potential for parapet collapse and therefore reduce the total number of fatalities in an earthquake. Building owners and engineers will be benefit from the design guidance provided by this project, which will lead to a suite of fully-tested and low-cost retrofit techniques.Read moreRead less
Mitigating Vehicular Crashes into Masonry Buildings . Around 2000 vehicles crash annually into school, home and shop buildings located at close proximity to heavily trafficked roads in Australia and cause significant distress to occupants of building and vehicle. The impacted walls mostly of masonry, suffer severe damage often with vehicle intrusion into the building. Despite this, the intrusion mechanism is not understood and no effective mitigation strategies exist at present. This project wi ....Mitigating Vehicular Crashes into Masonry Buildings . Around 2000 vehicles crash annually into school, home and shop buildings located at close proximity to heavily trafficked roads in Australia and cause significant distress to occupants of building and vehicle. The impacted walls mostly of masonry, suffer severe damage often with vehicle intrusion into the building. Despite this, the intrusion mechanism is not understood and no effective mitigation strategies exist at present. This project will uncover the mechanics of vehicle intrusions through masonry walls and develop novel mitigation strategies using high energy absorbing auxetic composite render and innovative vibration isolation at wall edges. These innovations will lead to new theories that can save lives in the building and vehicle.Read moreRead less
Development of ultra-high performance concrete columns against blasts. This project aims to develop cost-effective formulae for ultra-high performance fibre reinforced concrete (UHPFRC) material with superior strength, ductility and durability to replace conventional concrete in critical infrastructures.

This project aims to develop cost-effective formulae for ultra-high performance fibre reinforced concrete (UHPFRC) material with superior strength, ductility and durability to replace conventional concrete in critical infrastructures. In recent years, increasing threat from terrorism activities highlights the need to develop advanced building materials to protect against disastrous blasts; UHPFRC is an ideal option in structural protective design. This project plans to develop a mixed design approach for cost-effective UHPFRC material. It also plans to conduct blast tests and numerical investigations study blast resistance of UHPFRC columns and to develop analytical approaches and design methods for the application of such columns in critical infrastructure.Read moreRead less

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
Structural Fuses for Safer and More Economical Bridge Construction. This project aims to develop a novel structural system leading to more economical concrete bridge construction by utilising a customised structural fuse. A significant margin of safety is required in structural design to account for accidental over-loading and to reduce the risk of structural collapse. Such a margin leads to more material usage. Incorporation of a fuse into the structure that is triggered upon over-loading will ....Structural Fuses for Safer and More Economical Bridge Construction. This project aims to develop a novel structural system leading to more economical concrete bridge construction by utilising a customised structural fuse. A significant margin of safety is required in structural design to account for accidental over-loading and to reduce the risk of structural collapse. Such a margin leads to more material usage. Incorporation of a fuse into the structure that is triggered upon over-loading will cause a safer failure mode and prohibit further increase of loading, both of which result in a reduced structure without undermining safety. The project is expected to advance structural theory, and also provide significant benefits to the construction industry via cost reduction and more eco-friendly constructions.Read moreRead less

This project aims to provide structural engineers with the tools required to develop ultra-high performance fibre reinforced concrete materials and to utilise their unique material properties in design. Recent feasibility studies have shown that the replacement of conventional concrete and steel transport infrastructure with ultra-high performance fibre reinforced concrete has the potential to revolutionise the sector. For these cost savings benefits to be realised, guidelines for the low cost development and testing of new materials, and for the application in structural design are required. This project is expected to deliver these guidelines and potentially maximise the impact of government spending on road and rail infrastructure.Read moreRead less

The project aims to investigate the behaviour of and design hybrid multiple-tube concrete columns, a form of column. These columns allow the use of small circular high-strength steel tubes, readily available in the market, to suit the specific needs of construction projects of various scales. In the column, a durable outer tube made of fibre-reinforced polymer (FRP) composites protects steel tubes, and their high yield stress can be fully exploited through section configuration. The new column is expected to enable wider, safer and more economical use of FRP and high-strength steel, and meet demands for resilient civil infrastructure.Read moreRead less
