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
Harnessing properties of liquid metals for future devices. This project aims to hybridise low toxicity liquid metal alloys of gallium with surface confined functional micro/nano materials and explore fundamental new fluidic and physical-chemistry phenomena. Liquid metals are an under-used group of materials, but their combination of flexibility, bestowed by their room temperature fluidity, and metallic properties means they demonstrate startling behaviour. The expected outcomes are new devices a ....Harnessing properties of liquid metals for future devices.

Liquid metals are an under-used group of materials, but their combination of flexibility, bestowed by their room temperature fluidity, and metallic properties means they demonstrate startling behaviour. The expected outcomes are new devices and systems such as reconfigurable and highly efficient actuators/generators, catalysts, sensors, and electronic and optical components.Read moreRead less
Role of Reactive Particles in Explosive Emulsions. Concentrated water-in oil explosive emulsions are widely used in the minerals industry because they are cheap, easily detonated and relatively safe to handle. Their explosive energy can be significantly increased when reactive particles are introduced into the emulsion matrix. To do this, the interaction between the solid, oil, and water phases needs to be optimised. This investigation will increase our basic understanding of the physical and ch ....Role of Reactive Particles in Explosive Emulsions. Concentrated water-in oil explosive emulsions are widely used in the minerals industry because they are cheap, easily detonated and relatively safe to handle. Their explosive energy can be significantly increased when reactive particles are introduced into the emulsion matrix. To do this, the interaction between the solid, oil, and water phases needs to be optimised. This investigation will increase our basic understanding of the physical and chemical interactions that occur between the particle and the oil-water interface, and develop a more efficient explosive that can be produced continuously on a commercial scale.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.
Floating Forest – a breakwater for protecting the Australian coastline. This project aims to develop structural, materials and foundation solutions for a large floating forest that will act as a mega breakwater and windbreaker to protect the Australian coastline from strong waves and winds caused by climate change.

State-of-the-art facility for non-destructive testing of concrete infrastructure: There are many recent examples around the world where ageing concrete infrastructure has led to catastrophic failures with loss of life and severe damage to infrastructure. Non destructive testing (NDT) gives a reliable method to provide an accurate assessment of the condition of a structure. However NDT requires an understanding of the various methods available, and their capabilities and limitations, through systematic research projects. Very little research has been done in Australia and overseas in this area due to lack of facilities. This state-of-the-art testing equipment will provide Australian institutions with a cutting edge facility with portable equipment for NDT related research.Read moreRead less

To meet the national rail objectives as enunciated in the 2002 Green Paper there is an urgent requirement for a capability for: i) advanced (rail) prototype assessment, ii) rapid assessment of rail infra-structure, iii) for increasing the capacity of existing (rail) infra-structure. To address this we propose a facility with both a dissipative energy measurement and a 'lock in' thermograpghy capability. Recent Australian developments in thermo-elasticity enables the researchers to extend this facility to measure residual stress in complex components. The ability to measure dissipated energy, residual stress, ultrasonic waves, and full field stress will create a unique research capability.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
