This project aims to use advanced image analysis and cloud computing technologies to replace manual, time-consuming and subjective geotechnical engineering practices with a rapid, automated, and more rational approach. A new geo-materials testing system based on the existing triaxial apparatus will be developed that employs three-dimensional image capture hardware and advanced image analysis techniques. The data measured over the entire sample surface will feed into an automated, intelligent parameter selection procedure combining finite element analysis with numerical optimisation techniques.

An earthquake shaking table to investigate soil-structure interactions: This project aims to develop Australia's most advanced earthquake shaking table. Earthquakes are a problem of great significance to Australia. Infrastructure in civil, transport, mining and energy sectors may be at an unacceptable risk of damage under earthquake loading as current design practices do not account for the interaction between infrastructure and the ground under such loading. The shaking table will simulate earthquakes and enable controlled testing of three-tonne models of foundation and soil-structure interaction systems typical of Australia's infrastructure. The discoveries made are expected to be integral to the modernisation of Australia's seismic design standards so that earthquake-induced damage and risk exposure can be minimised.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

This project aims to develop an improved single-degree-of-freedom (SDOF) model which can be easily used in design analysis by engineers and yield accurate structural response predictions in analysis of structures subjected to blast and impact loads. Current practice uses SDOF models in analysis of structures subjected to blast and impact loads, however many experimental tests and high fidelity numerical simulations have revealed the SDOF analysis does not always lead to accurate structural response predictions. This project will develop an improved SDOF model, which can be easily used in design analysis by engineers and yield accurate structural response predictions. These will lead to more economical designs and robust structures that resist blast and impact loads.Read moreRead less

Measuring and modelling the mechanical response of soils incorporating recycled tyres. Civil engineers use backfill to refill excavated areas around new structures. They have found recently that rubber chips and shredded rubber make excellent backfill when combined with a small percentage of cement to make ‘rubber soil’. The widespread use of rubber soil therefore offers a tremendous opportunity to make use of a serious waste product to achieve important engineering outcomes.

They have found recently that rubber chips and shredded rubber make excellent backfill when combined with a small percentage of cement to make ‘rubber soil’. The widespread use of rubber soil therefore offers a tremendous opportunity to make use of a serious waste product to achieve important engineering outcomes. However, too little is known about the technology. This project will model the behaviour of rubber soil in order to introduce it as an environmentally sustainable, cost-effective and technically sound choice of geomaterial for both standard and non-standard geotechnical structures.Read moreRead less
