An earthquake shaking table to investigate soil-structure interactions: This project aims to develop Australia's most advanced earthquake shaking table. Earthquakes are a problem of great significance to Australia. Infrastructure in civil, transport, mining and energy sectors may be at an unacceptable risk of damage under earthquake loading as current design practices do not account for the interaction between infrastructure and the ground under such loading. The shaking table will simulate earthquakes and enable controlled testing of three-tonne models of foundation and soil-structure interaction systems typical of Australia's infrastructure. The discoveries made are expected to be integral to the modernisation of Australia's seismic design standards so that earthquake-induced damage and risk exposure can be minimised.Read moreRead less

Understanding material behaviour under dynamic loading is essential in dealing with many engineering problems as excavation, fragmentation, earthquake, blasting, and structure design. In geotechnical and structure projects, materials are often subjected to existing confining stresses. The full-field optical techniques, with an ultra-high speed and resolution camera in the system, aims to assist the quantitative measurement of deformation fields including small strain induced in brittle material's failure and identification of constitutive parameters.Read moreRead less

Summary
Seismic evaluation of non-structural unreinforced masonry components. This project aims to reduce earthquake risk posed by unreinforced masonry buildings. The project will use integrated experimental and numerical research to understand the dynamic interaction between timber floors, roofs and walls. New knowledge about this interaction will enable economical and safe earthquake design methods to be used for unreinforced masonry buildings.
Progressive collapse resistance of concrete flat plate structures. This project aims to systematically and thoroughly investigate the progressive collapse mechanisms and resistance capacity of concrete flat plate structures. They represent one of the most common construction systems used worldwide in modern days, yet their progressive collapse mechanisms require attention and limited collapse prevention design guidelines are available. The outcomes are expected to broaden and deepen the existing ....Progressive collapse resistance of concrete flat plate structures. This project aims to systematically and thoroughly investigate the progressive collapse mechanisms and resistance capacity of concrete flat plate structures. They represent one of the most common construction systems used worldwide in modern days, yet their progressive collapse mechanisms require attention and limited collapse prevention design guidelines are available. The outcomes are expected to broaden and deepen the existing theoretical framework and knowledge base, prevent injury and loss of life in both new and existing buildings. This is expected ultimately to contribute to the establishment of a set of collapse-resistant design guidelines for further development of relevant Australian and international standards.Read moreRead less
Erosion processes in soils across scales. This project aims to develop a monitoring tool for predicting the evolution of internal erosion in dams based on innovative electromagnetic observation methods. Internal erosion is an insidious process occurring in the obscurity of the soil’s pore system until its consequences become visible and threaten the stability of the dams. These water retaining structures are vital for the future water and energy supply for our society and their failure can be ca ....Erosion processes in soils across scales. This project aims to develop a monitoring tool for predicting the evolution of internal erosion in dams based on innovative electromagnetic observation methods. Internal erosion is an insidious process occurring in the obscurity of the soil’s pore system until its consequences become visible and threaten the stability of the dams. These water retaining structures are vital for the future water and energy supply for our society and their failure can be catastrophic. By establishing an improved understanding of internal erosion as a sequence of processes on various scales, from the onset of erosion until the failure of the structure, this project will place Australia at the forefront of dam safety assessment.Read moreRead less
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

The response of beams subjected to axial load and lateral soil movements. Beams (piles, soil nails, and pipelines) are not only subjected to axial (vertical, axial and longitudinal)loading, but often withstand simultaneous lateral loading, due to either explicit structural loads, or due to loads induced by movement of the soils in which they are founded. Bridge piles adjacent to an approach embankment are one example. This project will provide experimental evidence to assist with the estimation ....The response of beams subjected to axial load and lateral soil movements. Beams (piles, soil nails, and pipelines) are not only subjected to axial (vertical, axial and longitudinal)loading, but often withstand simultaneous lateral loading, due to either explicit structural loads, or due to loads induced by movement of the soils in which they are founded. Bridge piles adjacent to an approach embankment are one example. This project will provide experimental evidence to assist with the estimation of capacity, axial and shear resistance, the validation of unified solutions for beams subjected to simultaneous lateral soil movements and axial loads. Such experimental evidence and analytical solutions are not currently available. The evidence will also assist with solving a contradictory, existing design principle, which will lead to an economic and efficient design approach.Read moreRead less

Slope failures and landslides are a persistent cause of economic loss in Australia. Damages resulting from landslides include both property damage and loss of life. One such recent catastrophic slope failure is the landslide that occurred at Thredbo Village in New South Wales in 1997. This monumental landslide resulted in the deaths of 18 people and was considered by the coroner as the worst natural disaster in Australian history. The primary aim of this research project is to apply recently developed computational tools to better understand 3D slope behaviour and to develop rigorous stability solutions that can be used by design engineers. A better understanding of 3D slope failure will lead to more economic and safer slope designs.Read moreRead less
