Rapid structural condition assessment using adaptive model updating. The proposed project has potential to significantly enhance the accuracy with which the condition (and hence load bearing capacity) of existing infrastructure can be determined. By providing a technique of model updating that can be applied effectively in real time, location of damage will be able to be determined accurately. Economic benefits will be reaped, both through saving infrastructure from demolition where the conditio ....Rapid structural condition assessment using adaptive model updating. The proposed project has potential to significantly enhance the accuracy with which the condition (and hence load bearing capacity) of existing infrastructure can be determined. By providing a technique of model updating that can be applied effectively in real time, location of damage will be able to be determined accurately. Economic benefits will be reaped, both through saving infrastructure from demolition where the condition is found to be adequate, and by replacing or repairing inadequate structures before costly failure occurs. This is particularly important as much of Australia's infrastructure is aging, and unnecessary periodic replacement of infrastructure is not sustainable.Read moreRead less
Blast Damage and Fragmentation Prediction for Occupants and Structure Protection. Protecting infrastructures against blast loads from terrorist bombing or accidental explosion is a challenge. Researchers have been working on developing a numerical model, but the progress is slow owing to difficulties in modelling nonlinear and high strain rate damage process. Most blast effect assessment is based on empirical relations from blast tests. These have been demonstrated not necessarily yielding accur ....Blast Damage and Fragmentation Prediction for Occupants and Structure Protection. Protecting infrastructures against blast loads from terrorist bombing or accidental explosion is a challenge. Researchers have been working on developing a numerical model, but the progress is slow owing to difficulties in modelling nonlinear and high strain rate damage process. Most blast effect assessment is based on empirical relations from blast tests. These have been demonstrated not necessarily yielding accurate prediction owing to variations of structural properties from the test model. A reliable numerical model is therefore important. It will result in big savings from blast tests, and better prediction of blast effects for structure and occupant protection. It will have applications in civil, mining and defence engineering.

Understanding structural response to explosive loads is essential to protect critical infrastructure against terrorist bombing or industrial explosions. Current practice in analysis and design of structures to withstand explosive loads uses either empirical methods or a simplified structure model. In many cases, engineers need to know the structure response in more detail in order to protect the structure and plan evacuation procedures. This project will study the response and damage mechanism of structures to explosive loads, and develop a numerical model to predict structural response and damage. It will have immediate and wide-ranging applications in defence, construction and mining engineering.Read moreRead less
PROBABILISTIC BRIDGE STRUCTURE CONDITION ASSESSMENT AND LOAD CARRYING CAPACITY PREDICTION. Bridge failures have occasionally been reported around the world. Condition assessment of bridges is vital to maintain their safety. It is difficult to assess quantitatively the deterioration and damage using traditional methods.

Bridge failures have occasionally been reported around the world. Condition assessment of bridges is vital to maintain their safety. It is difficult to assess quantitatively the deterioration and damage using traditional methods. Vibration-based methods are very sensitive to noise in vibration measurement and error in finite element modelling. This project will study the effects of measurement noises and finite element model errors on bridge condition assessment, and develop improved techniques for predicting load carrying capacities of bridges. The technique developed will be applied to Main Roads WA bridges, will also be applicable to the assessment of other types of structures.Read moreRead less

Energy dissipation and vibration-assisted self-healing in structures with topological interlocking. High dissipation of impact and vibration energy, vibration-assisted self-healing, high tolerance to block failure and an ease of assembly/disassembly make topological interlocking structures ideal for safety barriers, protective shields and floating structures.

High dissipation of impact and vibration energy, vibration-assisted self-healing, high tolerance to block failure and an ease of assembly/disassembly make topological interlocking structures ideal for safety barriers, protective shields and floating structures. The theory of these phenomena will open a way for more efficient protection of infrastructure against both natural and human perpetrated impacts and for developing new methodology in constructing mobile marine bases. This constitutes the main benefit of the project. Furthermore, understanding the resonance structure of travelling waves will improve methods of non-destructive monitoring by back analysing spectral signatures of the waves.Read moreRead less
Continuum Damage Mechanics in Geotechnical Engineering. Mining and oil exploration are amongst the major industries in Australia and must address geotechnical problems in which growth in damage plays a central role. For example, failure of an offshore platform can occur under cyclic environmental loading, due to accumulated damage to the seabed soils. Design tools are therefore needed that incorporate continuum damage mechanics in modelling the response of geomaterials. The project will place Au ....Continuum Damage Mechanics in Geotechnical Engineering. Mining and oil exploration are amongst the major industries in Australia and must address geotechnical problems in which growth in damage plays a central role. For example, failure of an offshore platform can occur under cyclic environmental loading, due to accumulated damage to the seabed soils. Design tools are therefore needed that incorporate continuum damage mechanics in modelling the response of geomaterials. The project will place Australia at the forefront in this field through the development of rigorous yet simple numerical models that achieve this, and thus underpin safe but economic geotechnical engineering solutions in the mineral resource industries.Read moreRead less
