The newly developed floating structure will lead to future construction applications on the Australian harsh sea conditions that call for stringent requirements on infrastructures.Read moreRead less
Mitigating the Severity of Level Crossing Accidents and Derailments. Ongoing increases in the number of level crossings and heavy road vehicles cause more frequent and severe level crossing accidents and derailments. Despite the use of active warning systems, each year, on average, 100 level crossing accidents occur in Australia. With a view to mitigating these crashes, this research aims to formulate theories for reduction in crash energy and effective wheel constraints to prevent derailment by ....Mitigating the Severity of Level Crossing Accidents and Derailments. Ongoing increases in the number of level crossings and heavy road vehicles cause more frequent and severe level crossing accidents and derailments. Despite the use of active warning systems, each year, on average, 100 level crossing accidents occur in Australia. With a view to mitigating these crashes, this research aims to formulate theories for reduction in crash energy and effective wheel constraints to prevent derailment by modifying the levels of road and rail crossings and providing guard rails in the recesses of these modified level crossings. The theories are intended be developed using nonlinear dynamic computational methods and laboratory experiments. The outcomes are expected to enable reduction in the severity of level crossing accidents and hence save lives and costs of derailment.Read moreRead less
Development of Intelligent Structures that can Self-evaluate Deterioration. This project aims to transform traditional civil structures into smart structures that can accurately identify current and future structural deterioration conditions and automatically notify the infrastructure management authority for timely maintenance.

This project aims to transform traditional civil structures into smart structures that can accurately identify current and future structural deterioration conditions and automatically notify the infrastructure management authority for timely maintenance. Civil structures deteriorate over their long life spans. Currently, we have no effective method to identify when deterioration has reached the point where maintenance is required. The project plans to develop innovative structural deterioration evaluation systems using output-only vibration data and versatile optimisation algorithms to enable long-term deterioration assessment and maintenance management even under demanding operating conditions. These could be used with both conventional data acquisition systems and modern monitoring systems with smart wireless sensors. Expected project outcomes will enhance structural safety and maintenance efficiency.Read moreRead less
Thermal Upheaval Buckling of Functionally Graded Pavement Slabs. Upheaval buckling or blowup of concrete pavements due to high environment temperature is a serious problem in transportation infrastructure which quite often leads to road failure or even traffic hazards. The proposed project presents a combined theoretical, numerical and experimental investigation on the effective enhancement of thermal buckling capacity of pavement slabs with or without initial imperfection by using light and gre ....Thermal Upheaval Buckling of Functionally Graded Pavement Slabs. Upheaval buckling or blowup of concrete pavements due to high environment temperature is a serious problem in transportation infrastructure which quite often leads to road failure or even traffic hazards. The proposed project presents a combined theoretical, numerical and experimental investigation on the effective enhancement of thermal buckling capacity of pavement slabs with or without initial imperfection by using light and green functionally graded concrete materials with reduced usage of plain Portland cements for less carbon dioxide emissions. The research outcomes will contribute significantly to the society by offering a novel environmental friendly pavement solution with greatly improved road safety.Read moreRead less
Microbiological and abiotic marine corrosion of steel in particulate media. This project aims to study the complex interfacial physicochemical interaction between structural steel and inert particles in marine environments, including microbial growth influences. It will use field-testing and electrochemical laboratory experiments to understand the short- and long-term corrosion processes.

This project aims to study the complex interfacial physicochemical interaction between structural steel and inert particles in marine environments, including microbial growth influences. It will use field-testing and electrochemical laboratory experiments to understand the short- and long-term corrosion processes. It will develop mathematical models to predict likely corrosion loss and pitting, based on physicochemical corrosion principles. Industry increasingly needs such models to manage major infrastructure not protected against corrosion, including offshore energy systems, coastal structures and buried pipelines. These outcomes are expected to benefit Australian engineering consultants in the offshore energy industry, with potential for large foreign exchange earnings.Read moreRead less
Sustainable retirement villages for Ageing Australians. This project aims to deliver sustainable retirement villages to better accommodate older Australians and assess their effects on the growth of the retirement village industry. More organisations and governments globally are embracing sustainable development, but the Australian retirement village industry has been largely static and unresponsive; it has not yet met the green movement’s challenge to provide a sustainable living environment fo ....Sustainable retirement villages for Ageing Australians. This project aims to deliver sustainable retirement villages to better accommodate older Australians and assess their effects on the growth of the retirement village industry. More organisations and governments globally are embracing sustainable development, but the Australian retirement village industry has been largely static and unresponsive; it has not yet met the green movement’s challenge to provide a sustainable living environment for senior citizens. This project is expected to improve the living environment of retirement villages and the quality of life of older Australians.Read moreRead less
Design and Construction Error Mitigation in Infrastructure Projects. Human errors committed during the design and construction process of infrastructure projects increase costs by as much as 25 per cent. The costs associated with such errors would be significantly higher in the event of an engineering failure and loss of life. This research will develop a model that can be used to mitigate errors and improve the performance and safety of infrastructure projects. A reduction in errors will reduce ....Design and Construction Error Mitigation in Infrastructure Projects. Human errors committed during the design and construction process of infrastructure projects increase costs by as much as 25 per cent. The costs associated with such errors would be significantly higher in the event of an engineering failure and loss of life. This research will develop a model that can be used to mitigate errors and improve the performance and safety of infrastructure projects. A reduction in errors will reduce the financial burden placed on taxpayers for cost overruns experienced as well as improve the profitability of organisations. This will lead to greater investment, and contribution to gross domestic product.Read moreRead less
