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.

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

This project aims to develop an innovative composite panel system using aerated geopolymer and a thin high strength steel casing. The new panel system aims to have a number of significant enhancements compared to traditional panels in terms of load resistance, much lower carbon footprint and life-cycle costs. It aims to offer desirable properties, such as being light-weight, easy to construct, economical, recyclable and reusable. A significant gap in knowledge exists in the material and system behaviour of the aerated geopolymer and its fire performance. It is intended that a comprehensive research program will be carried out to address those challenges and to provide design guidelines to rapidly progress these technologies in Australia and overseas.Read moreRead less

Summary
Free-forming and function-integrated composite structures for future green building construction. The free expression of structure in space is a constant pursuit for architects while being a complex task for engineers. Fibre-reinforced polymer sandwiches provide an ideal way to address this challenge. This project aims to develop a novel free-forming system using such elements and explore their thermal-energy-light multifunctional integration.
Concrete Enriched with Carbon Nanotubes for Advanced Future Construction. This project aims to develop an advanced construction material based on enrichment of concrete with carbon nanotubes (CNT). Concrete, the most consumed construction material globally, is brittle and needs embedded steel reinforcement. Concrete enriched with CNT, one of the strongest known fibres, may partially replace conventional bulky and heavier steel reinforcement thereby creating economies (e.g. thinner section sizes) ....Concrete Enriched with Carbon Nanotubes for Advanced Future Construction. This project aims to develop an advanced construction material based on enrichment of concrete with carbon nanotubes (CNT). Concrete, the most consumed construction material globally, is brittle and needs embedded steel reinforcement. Concrete enriched with CNT, one of the strongest known fibres, may partially replace conventional bulky and heavier steel reinforcement thereby creating economies (e.g. thinner section sizes), and reduced carbon dioxide emissions by expending less steel and cement for construction. This project extends earlier research by the research team and aims to transform cement-CNT pastes into construction-scale concrete by resolving uncertainties associated with scaling.Read moreRead less

The project plans to develop a model of the mechanism of drying shrinkage and associated cracking in soils. Soil desiccation cracking can adversely affect the stability and performance of many vital geo-infrastructures. For example, desiccation cracks have contributed to dam and slope failures incurring significant damages. Our understanding of the mechanism of drying shrinkage cracking and ways to control or avoid such cracking in soils is not yet fully developed. This project aims to advance knowledge of the nature of crack initiation and propagation in clayey soils induced by moisture evaporation, through the use of advanced experimental and modelling techniques. Outcomes are expected to lead to new continuum models for reliable prediction of soil desiccation cracking.Read moreRead less

This project aims to investigate the electro-mechanical behaviours of carbon nanotube reinforced polymer composite structures. Such structures demonstrate considerable potential in structural health monitoring and strengthening due to their unique electro-mechanical behaviours. However, the electro-mechanical behaviours of these composites remain unclear due to the multiscale nature of the problems and the constraint of current techniques to capture nanoscale features that underpin the macroscopic behaviours. This project aims to investigate the electro-mechanical behaviours of these composites and their structures via atomistic simulation and continuum mechanics modelling. The outcomes are intended to enhance the application of these multifunctional composites and improve the performances and sustainability of engineering structures.Read moreRead less
