This will include the development of innovative numerical methods for effective modelling of crack propagation and closure, large slips on crack faces and weak interfaces, dam-reservoir interaction, dam-foundation interaction and automatic mesh generation. The expected outcomes of the project will be a significantly improved prediction tool. It is also anticipated that the project will result in improvements in dam and public safety, and more efficient use of funds for dam safety upgrades and management.Read moreRead less
Erosion of embankment dams and dam spillways. In excess of $250M is spent annually to maintain, upgrade, improve safety and monitor performance of Australian dams. Improved methods for assessing both spillway and internal erosion, the cause of 50 per cent of embankment dam failures and incidents requiring repairs, will be developed, maximising dam safety and minimising maintenance expenditure.
Behaviour of ultra-high strength double-skin composite tubular construction. Ultra-high strength (UHS) steel tubes are currently used mainly in the vehicle industry due to their high strength and light weight. This project aims to enable the building of more resilient and sustainable infrastructure by utilising these UHS steel tubes in double-skin composite tubular construction. To date there has been little work to understand the effects of fire, earthquake and impact related incidents on these ....Behaviour of ultra-high strength double-skin composite tubular construction. Ultra-high strength (UHS) steel tubes are currently used mainly in the vehicle industry due to their high strength and light weight. This project aims to enable the building of more resilient and sustainable infrastructure by utilising these UHS steel tubes in double-skin composite tubular construction. To date there has been little work to understand the effects of fire, earthquake and impact related incidents on these structures. This project aims to access unique testing facilities for full size impact and fire testing and the state-of-the-art hybrid testing simulation. It is expected to increase the competitiveness of the Australian manufacturing industry by overcoming the bottleneck in the manufacture of steel sections.Read moreRead less
Composite tubular construction subject to impact and blast loading. This project will advance the knowledge of composite tubular members and connections under impact and blast loading. It will provide confident design methodology against impact and blast loading for buildings designated as prominent targets or items of critical infrastructure, to save lives and reduce losses.
Developing innovative concrete composites by upscaling material properties. This project aims to develop an upscaling process to correlate micro-nano properties of engineering materials to their comprehensive physicochemical properties based on systematic mechanical and statistical analysis approaches and nanoindentation technology. The process will enable assessing material mechanical and viscoelastic properties at a microscale level thus will generate a new knowledge in structural engineering ....Developing innovative concrete composites by upscaling material properties. This project aims to develop an upscaling process to correlate micro-nano properties of engineering materials to their comprehensive physicochemical properties based on systematic mechanical and statistical analysis approaches and nanoindentation technology. The process will enable assessing material mechanical and viscoelastic properties at a microscale level thus will generate a new knowledge in structural engineering discipline including health monitoring, assessment of existing structures, historical buildings, and strengthening and repairing materials in structures. The outcomes are a multiscale link model for upscaling material properties and a development of innovative reinforced concrete composites which are cost-effective and efficient.Read moreRead less

Reliability assessment of concrete-filled steel tubular frames designed by advanced analysis. Concrete-filled steel tubular structures have been increasingly used in high-rise buildings, bridges and other infrastructure due to their enhanced properties such as high strength, high ductility and large energy absorption capability.

Concrete-filled steel tubular structures have been increasingly used in high-rise buildings, bridges and other infrastructure due to their enhanced properties such as high strength, high ductility and large energy absorption capability. This project will evaluate the system reliability of concrete-filled steel tubular frames designed by advanced analysis. The influences of inherent uncertainties in loads, strength capacities, material properties and geometric properties on the system reliability of such frames will be studied. The outcomes of this project will be used to develop reliability-based provisions to achieve a target reliability range in the design of concrete-filled steel tubular structures.Read moreRead less

This project aims to build a risk-based framework for managing micro- and nano-plastic particles in landfills and surrounding environments. It expects to develop a new experimentally validated theory of micro/nano-plastic transport in soils, focussing on lining systems used in landfills worldwide to protect aquifers from contamination. The project will use state-of-the-art experimental, theoretical and computational approaches to generate new knowledge on micro/nano-plastic fate in lining systems and their effects on the mobility of heavy metals and organic pollutants. This should provide significant benefits including safe plastic containment and groundwater protection from landfill waste, a major reservoir of plastic in the environment.Read moreRead less

The national drop weight impact testing facility aims to enable dynamic tests on geo- and construction materials and systems. This facility aims to provide state-of-the-art technology to observe the real-time behaviour of elements and sub-assemblies under combined quasi-static and impact loading. Understanding material behaviour under dynamic loading is essential in dealing with many engineering problems. The facility may advance understanding of the fundamental behaviour of critical infrastructure exposed to impact loading and will foster innovations in design and construction. Applications may include improvement of the structural safety of infrastructure including railway networks, tunnels and bridges, and also the development of cost-effective and environmentally friendly building and construction materials.

Advancing water pollution emissions modelling in cities of the future. This project aims to advance stormwater pollution modelling and enhance its link with urban development. Management of stormwater pollution by industry often results in inadequate strategies and, crucially, sub-optimal financial investments. Since this is unlikely to improve in light of urban growth and climate change, addressing decade-old pollution modelling knowledge gaps and the lack of a multidisciplinary approach to stormwater pollution management is urgent. The anticipated outcome is a modelling tool which industry can use to manage stormwater pollution in changing cities through smarter and economic technology and policy.Read moreRead less
