Development of next generation prestressed concrete bridges using moving force identification. This project will enhance the safety of prestressed concrete bridges which constitute 70 per cent of Australian bridges and hence provide economic benefits. The procedure developed can evaluate the health status of these bridges and the prestressing force which was hitherto difficult to determine, even though it controls bridge load carrying capacity.
Light steel roof and wall systems under combined wind and bushfire actions. The project aims to investigate the complex behaviour of light cold-formed-steel roof and wall systems involving localized failures under the combined action of wind and bushfire using wind suction tests at elevated temperatures combined with advanced numerical modelling. It will generate new knowledge of the behaviour and strength of cold-formed-steel roof and wall systems under bushfire conditions. Expected outcomes in ....Light steel roof and wall systems under combined wind and bushfire actions. The project aims to investigate the complex behaviour of light cold-formed-steel roof and wall systems involving localized failures under the combined action of wind and bushfire using wind suction tests at elevated temperatures combined with advanced numerical modelling. It will generate new knowledge of the behaviour and strength of cold-formed-steel roof and wall systems under bushfire conditions. Expected outcomes include new design models for wind, bushfire and cold-formed-steel Standards. This will significantly improve the bushfire safety of buildings, since non-combustible steel roof and wall systems are used as building envelopes in bushfire prone areas, but are not designed to withstand recently discovered bushfire-enhanced winds.Read moreRead less
Development of Intelligent Structures that can Self-evaluate Deterioration. This project aims to transform traditional civil structures into smart structures that can accurately identify current and future structural deterioration conditions and automatically notify the infrastructure management authority for timely maintenance.

This project aims to transform traditional civil structures into smart structures that can accurately identify current and future structural deterioration conditions and automatically notify the infrastructure management authority for timely maintenance. Civil structures deteriorate over their long life spans. Currently, we have no effective method to identify when deterioration has reached the point where maintenance is required. The project plans to develop innovative structural deterioration evaluation systems using output-only vibration data and versatile optimisation algorithms to enable long-term deterioration assessment and maintenance management even under demanding operating conditions. These could be used with both conventional data acquisition systems and modern monitoring systems with smart wireless sensors. Expected project outcomes will enhance structural safety and maintenance efficiency.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
Mitigating the Severity of Level Crossing Accidents and Derailments. Ongoing increases in the number of level crossings and heavy road vehicles cause more frequent and severe level crossing accidents and derailments. Despite the use of active warning systems, each year, on average, 100 level crossing accidents occur in Australia. With a view to mitigating these crashes, this research aims to formulate theories for reduction in crash energy and effective wheel constraints to prevent derailment by ....Mitigating the Severity of Level Crossing Accidents and Derailments. Ongoing increases in the number of level crossings and heavy road vehicles cause more frequent and severe level crossing accidents and derailments. Despite the use of active warning systems, each year, on average, 100 level crossing accidents occur in Australia. With a view to mitigating these crashes, this research aims to formulate theories for reduction in crash energy and effective wheel constraints to prevent derailment by modifying the levels of road and rail crossings and providing guard rails in the recesses of these modified level crossings. The theories are intended be developed using nonlinear dynamic computational methods and laboratory experiments. The outcomes are expected to enable reduction in the severity of level crossing accidents and hence save lives and costs of derailment.Read moreRead less

LSF systems are increasingly used in homes and offices. The project plans to investigate fundamental thermal, structural and energy performances of LSF walls and their components using experimental and numerical studies. It plans to develop enhanced plasterboards, insulations and innovative composite panels using suitable nanomaterials, chemical additives, fillers and phase-change materials and use these with innovative wall configurations to significantly improve the fire and energy performance of LSF walls. The new wall systems may increase occupant comfort and safety, reduce business losses in fires, and lead to low-energy buildings.Read moreRead less
