Developing auxetic composite system for protective engineering applications. This project intends to explore the possibilities of extending the latest developments in auxetic technologies to the protective design of engineering structures. Auxetic materials become thicker perpendicular to the applied force when stretched. Specifically, the project plans to develop a novel auxetic composite system with a focus on protecting civil and defence infrastructure from extreme loads.

This project intends to explore the possibilities of extending the latest developments in auxetic technologies to the protective design of engineering structures. Auxetic materials become thicker perpendicular to the applied force when stretched. Specifically, the project plans to develop a novel auxetic composite system with a focus on protecting civil and defence infrastructure from extreme loads. It is expected that the system’s superior energy dissipating capability will broaden its application beyond civil infrastructure, such as armoured vehicles, protective sports gear and body armour. The project also plans to develop a multiscale numerical modelling and topological optimisation framework to accelerate the adoption of this advanced composite system.Read moreRead less

Seismic performance of concrete beam-slab-column systems constructed with a re-useable sheet metal formwork system. When designing for earthquake induced loading it is very important to know the ductility and any other inherent deficiencies in structural systems under lateral deflections. The main purpose of this application is to investigate the seismic performance of an efficient beam-slab-column system constructed with a re-useable sheet metal formwork system, Corcon, which is becoming popula ....Seismic performance of concrete beam-slab-column systems constructed with a re-useable sheet metal formwork system. When designing for earthquake induced loading it is very important to know the ductility and any other inherent deficiencies in structural systems under lateral deflections. The main purpose of this application is to investigate the seismic performance of an efficient beam-slab-column system constructed with a re-useable sheet metal formwork system, Corcon, which is becoming popular in Australia and overseas. The proposed research will ultimately lead to revised design guidelines for these systems, suitable for local and overseas practice where different levels of seismicity occur.

This proposed project combines the expertise and disciplines of residential construction, structural dynamics and blasting technology. The ultimate aim of the project is to develop a rational methodology for assessing the damage potential of ground vibration resulting from blasting on typical Australian residential structures. The project involves field blast vibration measurements, static and dynamic laboratory tests on structural sub-assemblages in a controlled environment, and comprehensive analytical modelling of both loading and response. The outcomes from this research will have direct application to the mining, insurance, construction and defence industries.Read moreRead less
Performance based assessment of building cladding against hailstorms. Hailstorms cause billions of dollars of damage in Australia and hailstorm events are increasing in frequency with climate change. Robust cladding to resist extreme weather events is imperative for new and existing building stock.

Hailstorms cause billions of dollars of damage in Australia and hailstorm events are increasing in frequency with climate change. Robust cladding to resist extreme weather events is imperative for new and existing building stock. This project will develop technology to accurately assess the performance of aluminium cladding, glass facades and skylights under severe hailstorm events. The research outcomes will enable cost-effective design of robust cladding solutions and the evaluation of the performance of existing cladding. This will benefit asset managers, homeowners, the insurance industry and the building and construction industry, and help save billions of dollars of economic loss.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.
Failure Mechanisms of Roof Cladding under Fluctuating Wind Loads. Wind damage to low-rise buildings cause disruption to communities and result in economic losses. Improvements to the most vulnerable part (i.e. roof) will therefore have national benefits and associated economic benefits. Currently, roofing systems used in cyclonic areas are evaluated to DABM in the Northern Territory and to TR440 elsewhere, requiring the same product be tested under two different (and unsatisfactory) specificat ....Failure Mechanisms of Roof Cladding under Fluctuating Wind Loads. Wind damage to low-rise buildings cause disruption to communities and result in economic losses. Improvements to the most vulnerable part (i.e. roof) will therefore have national benefits and associated economic benefits. Currently, roofing systems used in cyclonic areas are evaluated to DABM in the Northern Territory and to TR440 elsewhere, requiring the same product be tested under two different (and unsatisfactory) specifications. This is due to the limited understanding of wind-induced fatigue of cladding. This project will provide the framework for understanding and minimizing cladding fatigue. A realistic single test will also reduce cost and result in better design systems.Read moreRead less
Fatigue Behaviour of Dragline Tubular Structures. Fatigue failure is a major concern for dragline tubular structures. Several catastrophic collapses of such structure occurred. The fatigue behaviour of such large tubular structures is unknown. Fatigue cracks were observed in many existing draglines. The latest international design codes are inadequate to address this issue. The project will develop reliable methodologies for design, inspection, strengthening and assessment of such structures. Th ....Fatigue Behaviour of Dragline Tubular Structures.
