This project aims to develop optimised interlocking bricks to resist static and earthquake loads. Using conventional bricks in masonry construction requires skilled labour to connect bricks with mortar. Development of interlocking bricks for mortarless connection has been attracting great interest because the easy alignment improves construction efficiency and quality. Interlocking also leads to better mechanical performance of the resulting structures. This project will have significant impact on construction technology and the Australian masonry industry, and greatly improve the competitiveness of the Australian construction industry in the international market.Read moreRead less
Numerical and experimental study of pounding damage of adjacent bridge structures to spatially varying earthquake ground motions. Bridge damage in an earthquake prevents rescue personnel and equipment from quick access to the affected area. Repairing or replacing a damaged bridge and the increased commuting time after the earthquake may have a significant impact on the economy and life of the general public. This project will develop techniques for earthquake-resistant bridge design.

Using Sandwich Pipe for Pipeline Vibration Control. 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.

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

Development of multi-hazard resilient and sustainable infrastructure. This project aims to develop next generation construction of multi-hazard resilient structures for the safety and wellbeing of the public, society and economy, as well as structural health monitoring techniques for effective engineering asset management.

This project aims to develop next generation construction of multi-hazard resilient structures for the safety and wellbeing of the public, society and economy, as well as structural health monitoring techniques for effective engineering asset management. Sustainable infrastructure development involves the use of green materials to reduce greenhouse gas emission, and new technologies to reduce construction and life-cycle maintenance cost. The project will use new green materials and techniques to prefabricate structural components which can be easily assembled and dismantled to meet the requirement for adaptation to technology advancement, urban planning and climate change. The project will advance the construction practice for sustainable infrastructure development.Read moreRead less
Vulnerability mapping of hazards and economic loss assessment of offshore oil and gas platforms subject to accidental explosion and fires. In Australia, up to 100 offshore oil and gas wells per year are drilled, but fire and explosion are a risk. This project develops vulnerability maps of offshore platforms subjected to accidental explosions, so that economic loss, environmental and social impact can be effectively assessed based on these factors and mitigation measures can be introduced.
Geotechnical and soil-structure interaction properties of soils in Perth CBD. A new underground railway (City Project) will shortly begin construction in Perth CBD.

This construction, and its associated high level of monitoring instrumentation, offers a unique opportunity for an extensive and thorough examination of the mechanical properties of Perths soils. The research results emanating from the proposed combination of field monitoring, laboratory investigation and numerical analysis, will greatly improve the reliability (and hence cost) of future foundation and basement designs in Perth and elsewhere.Read moreRead less
Numerical prediction of train and vehicle induced ground vibrations and their effects on structures. This project will develop an innovative new method based on coupled finite element and scaled boundary finite-element analysis for predicting the ground vibrations induced by road traffic and underground or surface trains.

This project will develop an innovative new method based on coupled finite element and scaled boundary finite-element analysis for predicting the ground vibrations induced by road traffic and underground or surface trains. The method will have immediate application in transportation engineering to predict traffic-induced ground vibrations, in geotechnical engineering to design isolation trenches and wave barriers to dissipate wave propagation, and in structural engineering to estimate in-structure vibration level and design isolators for sensitive equipment housed within. The technique will involve fundamental advances in the scaled boundary finite-element method, as calculations will be performed in a moving reference frame.Read moreRead less
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.

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.
