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
An innovative light weight composite panel system for high speed modular construction. 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.

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

New generation facility for impact testing. This project aims to develop a new generation, national-impact testing facility to study the impact response of civil and mechanical structures and components. This project expects to seek simultaneous, realistic impact scenarios with very high velocities, which were previously impossible.

This project aims to develop a new generation, national-impact testing facility to study the impact response of civil and mechanical structures and components. This project expects to seek simultaneous, realistic impact scenarios with very high velocities, which were previously impossible. This will enhance the capability for innovative research on real-time behaviour of components/systems under high amplitude impacts to augment their protection through advanced materials. This project is essential for research on rational design philosophies and effective retrofitting of high-risk buildings, infrastructure and armoured vehicles. Benefits include the saving of lives and property through new knowledge from credible impact testing.Read moreRead less
Improved analysis and design of structures to resist blast and impact. 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.

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
Development of Precast Concrete Segmental Columns to Resist Dynamic Loads. Using precast segmental concrete columns in structures improves the construction efficiency and site safety, leads to better construction quality control, and reduces the construction cost, site disruption and environmental impacts. The performance of segmental columns to resist earthquake and blast loads is not well studied yet. As a structure might be subject to such loads during its service life, understanding its resi ....Development of Precast Concrete Segmental Columns to Resist Dynamic Loads. Using precast segmental concrete columns in structures improves the construction efficiency and site safety, leads to better construction quality control, and reduces the construction cost, site disruption and environmental impacts. The performance of segmental columns to resist earthquake and blast loads is not well studied yet. As a structure might be subject to such loads during its service life, understanding its resistance capacities is essential for structural safety. This project aims to perform experimental and numerical investigations to study the performance of precast segmental concrete columns under earthquake and blast loads, and develop analytical and design methods for applications of such columns in building and bridge structures.Read moreRead less
Development of advanced deterioration model for the design of stabilised pavement bases. The Australian road network is a lifeline infrastructure that underpins the nation's living standards and economy. Much of these roads have deteriorated and require rehabilitation to get a new lease of life. This project intends to develop advanced methods to extend the lives of these pavements using in-situ recycling of old pavement materials.
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. However, too little ....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. 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

Advancing laterally loaded pile analysis. This project will replace out-of-date solution techniques for the design of pile foundations subjected to wind, waves and other horizontally applied forces and, in so doing, lead to more efficient designs of the foundations for structures such as elevated highways, tall buildings, bridges, jetties, towers, wind turbines and offshore platforms.
Development of ambient cured high performance geopolymer composite. The project intends to develop an ambient-cured high-performance, sustainable, fibre-reinforced geopolymer composite for construction. Compared to cement, which is currently used extensively in the construction industry, production of the geopolymer material not only recycles industry wastes which would otherwise end up in landfills, but also consumes less energy and emits significantly less greenhouse gases into the atmosphere. ....Development of ambient cured high performance geopolymer composite.

Compared to cement, which is currently used extensively in the construction industry, production of the geopolymer material not only recycles industry wastes which would otherwise end up in landfills, but also consumes less energy and emits significantly less greenhouse gases into the atmosphere. The composite is also designed to have a higher strength and deformation ability than cementitious material. The project plans to perform intensive experimental tests to determine the optimal mix for the best performing material, and develop material and numerical models to predict the responses of structures made from the composite when subjected to static and dynamic loads.Read moreRead less
