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
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

This project seeks to advance our understanding of bushfire–wind interaction to improve current design standards for buildings against bushfire-enhanced winds. Bushfire-enhanced winds have caused considerable property damage and loss of lives. The project aims to identify the mechanisms governing bushfire–wind interaction and determine the wind load effects on buildings due to bushfire-enhanced wind. It aims to do so by using advanced computation techniques and unique fire-wind tunnel test facility. This knowledge is designed to guide the development of improved building construction standards for bushfire-prone regions to facilitate the design and construction of a new generation of bushfire-resistant buildings that safeguard lives and properties against the increasing threat of bushfire due to climate change.Read moreRead less
Hybrid stainless-carbon steel composite beam-column joints at ambient and elevated temperatures. This project will consider the behaviour of hybrid stainless-carbon steel composite beam-column joints at ambient and elevated temperatures. By incorporating into potential design codes, the results can promote the application of stainless steel in structures, thereby increasing Australia's maintenance capability of structures.
Control of cracking caused by early-age contraction of concrete. An extensive program of laboratory testing will be undertaken to quantify the extent of cracking in concrete walls and slabs due to early-age cooling and shrinkage of concrete. Analytical models for quantifying restraint in walls and slabs will be developed, as will methods for the prediction and control of crack widths and crack spacings.
Multi-scale modeling of transport through deformable porous materials. Understanding solute transport through porous materials is essential because it provides a technical basis for answering many important questions in society today-how can humans avoid 'brittle bones', how to design durable infrastructure, how to safely store wastes (e.g. hazardous and municipal). Solution of each of these problems requires innovation in model development, new method of analysis, and insightful interpretation ....Multi-scale modeling of transport through deformable porous materials. Understanding solute transport through porous materials is essential because it provides a technical basis for answering many important questions in society today-how can humans avoid 'brittle bones', how to design durable infrastructure, how to safely store wastes (e.g. hazardous and municipal). Solution of each of these problems requires innovation in model development, new method of analysis, and insightful interpretation of results. While theoretical developments of this project are general, in the sense that they are not restricted to particular engineering disciplines, the four chosen applications closely align with two major research priorities namely An Environmental Sustainable Australia and Promoting and Maintaining Good Health.Read moreRead less
Containment and reduction of rework in offshore oil and gas projects. This research will ensure that hydrocarbon projects are delivered successfully, on time and budget, safely to specified quality and with minimal environment impact. The successful delivery of such projects is thwarted by rework made during the design process. Strategies to reduce rework from occurring in the future will be developed.
