A complex systems approach to granular rheology: interconnecting topology, stability, dynamics and function. The response of granular materials (e.g. soil, rocks) to applied stresses and strains will be characterised in detail. Information mined from experimental and simulation tests will be used to develop robust predictive models of granular behaviour, crucial for effective earthquake mitigation as well as greener mining and construction technologies.
Response of residential structures to blast vibration. 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-assem ....Response of residential structures to blast vibration. 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
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. 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. The outcome will be reduced manufacturing and operational costs and a reduced catastrophic failure risk. This will increase the international competitiveness of Australian mining industry. Several other industry sectors will be benefited from the technology developed in this project.Read moreRead less
Geomechanics of multiple seam mining interactions. This project will address a highly significant and timely problem that has arisen in the coal mining industry. Through the application of scientific principles and advanced methods of engineering analysis, this research will develop practical guidelines that in turn will provide the means for rational planning of multi-seam mining operations.
Predicting the foundation performance of offshore jack-up drilling rigs in intermediate soils. The research outcomes will be a major step forward in creating safer operations of mobile platforms in our challenging seabed conditions. The new models and guidelines will assist engineers in the efficient expansion of our offshore oil and gas industry, with significant increased investment projected over the next five years.

Pipelines are important structures but are vulnerable to different types of damage. This damage is often associated with pipeline vibration. It is important to control adverse vibrations to reduce the risk of catastrophic damage. This project proposes using sandwich pipe to suppress different sources of vibrations that may be experienced during the lifetime of the pipeline. Analytical, numerical and experimental investigations will be carried out to demonstrate the feasibility of the proposed method. The project aims to develop direct applications for designing pipelines to suppress different sources of vibration and to guarantee the safety of pipelines.Read moreRead less
Modelling and simulation of complex granular flows. Granular flows are of crucial importance in a wide range of problems related to civil infrastructure. These include landslides and similar catastrophic events, often leading to loss of life and property. The project aims to develop new methods for accurate prediction of such events thus allowing for the formulation of efficient mitigation strategies.
