Bed shear stress on beach sediment and coastal structures under wave run-up. The aim of this work is to obtain critical new information about the way waves interact with the coast and the damage they can cause to beaches and coastal protection structures. This new data will provide the basis for improved predictions of coastal erosion and better coastal engineering design in the face of sea-level rise and climate change.

Dynamic soil structure interaction. The aim of this project is to undertake a study of an important class of geotechnical problems in which systems composed of soil, structure and pore water are subjected to dynamic or impact loading. The outcomes will include safer and more efficient methods for designing geotechnical structures subjected to dynamic loading.

Predicting internal erosion in dams using real-time coupled experiments. Internal erosion causes nearly half of embankment dam failures globally. This project aims to develop a mechanics-based understanding of internal erosion to overcome the limitations of existing empirical approaches that do not capture the underlying physics. By innovatively coupling computational and physical experiments in real-time, this project expects to generate new insights that identify the factors leading to the ini ....Predicting internal erosion in dams using real-time coupled experiments. Internal erosion causes nearly half of embankment dam failures globally. This project aims to develop a mechanics-based understanding of internal erosion to overcome the limitations of existing empirical approaches that do not capture the underlying physics. By innovatively coupling computational and physical experiments in real-time, this project expects to generate new insights that identify the factors leading to the initiation and continuation of internal erosion. The expected outcome of this project is a probabilistic framework able to predict the internal erosion process. This should significantly enhance and inform the design of erosion control measures and provide a holistic risk assessment for embankment dams.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. 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 prove ....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. 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. Failure of the shear walls can result in building collapse causing injuries and death and significant economy losses. Through experi ....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. 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. The ability to more accurately evaluate the safety of exi ....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. 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

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.

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.
