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
Gas Explosion Resistance of Non-Cement Based High Performance Concrete. This project aims to study gas explosion resistance of non-cement-based ultra-high performance concrete after fire hazards. Fuel gases such as natural gas and hydrogen are becoming increasingly more popular in Australia.

This project aims to study gas explosion resistance of non-cement-based ultra-high performance concrete after fire hazards. Fuel gases such as natural gas and hydrogen are becoming increasingly more popular in Australia. Due to their wide flammability range, there is considerable concern about the potential fire and explosion hazard. Until now, there is limited knowledge on this topic and conventional concrete has been proved incapable of handling this multi-hazard scenario. The expected outcomes of this project include a detailed knowledge of multi-hazard scenario and a safety design with the non-cement-based ultra-high performance concrete. Successful delivery of this project ensures structural safety in Australia and wider community.Read moreRead less
Structural safety and reliability of unreinforced masonry shear walls. This project aims to investigate and quantify the role of spatial variability of material properties in the failure behaviour and safety of unreinforced masonry shear walls. In masonry buildings, shear walls provide the primary means for safely resisting lateral loads due to wind and earthquake.

This project aims to investigate and quantify the role of spatial variability of material properties in the failure behaviour and safety of unreinforced masonry shear walls. In masonry buildings, shear walls provide the primary means for safely resisting lateral loads due to wind and earthquake. Failure of the shear walls can result in building collapse causing injuries and death and significant economy losses. Through experimental testing and numerical modelling the project will enable improved techniques for the assessment and design of masonry walls which account, for the first time, for the influence that spatial variability of material properties has in determining the failure behaviour and capacity of masonry shear walls.

Stochastic hazard assessment of unreinforced masonry wall systems. This project aims to develop an improved understanding of the effects of wall-ties on structural behaviour and reliability of masonry wall systems. A comparison of structural reliabilities for new and existing construction will provide quantitative evidence of whether or not existing design criteria are inconsistent, too conservative in some cases, or incautious in others.

This project aims to develop an improved understanding of the effects of wall-ties on structural behaviour and reliability of masonry wall systems. A comparison of structural reliabilities for new and existing construction will provide quantitative evidence of whether or not existing design criteria are inconsistent, too conservative in some cases, or incautious in others. The ability to more accurately evaluate the safety of existing masonry structures will likely allow authorities to avoid unnecessary demolition or rehabilitation of such structures, or to correctly identify when such measures are essential. A more efficient use of structural masonry can reduce greenhouse gas emissions and enhance the sustainability of construction.Read moreRead less
