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
Structural Protection of flywheel energy storage system . A flywheel energy storage system stores a large amount of energy in a rotating mass. Compared with other energy storage systems such as large-capacity batteries, the flywheel energy storage system features high power density, long lifespan, high efficiency and is carbon-free. Flywheel energy storage systems are typically constructed underground due to safety concerns from a potential rotor burst. In the present project, a high-performance ....Structural Protection of flywheel energy storage system . A flywheel energy storage system stores a large amount of energy in a rotating mass. Compared with other energy storage systems such as large-capacity batteries, the flywheel energy storage system features high power density, long lifespan, high efficiency and is carbon-free. Flywheel energy storage systems are typically constructed underground due to safety concerns from a potential rotor burst. In the present project, a high-performance confinement system is developed aiming at above-ground construction. The confinement systems which comprise low-carbon, rubberized concrete, energy-absorbing aluminum foam, and ductile steel cladding will allow for high-impact resistance, off-site prefabrication, and easy on-site installation.

Designing for wellbeing: realizing benefits for patients through best practice hospital design. The environmental design of healthcare facilities has been shown to directly affect the wellbeing of patients and their families. Poorly designed environments exacerbate patient anxiety and stress and diminish their healthcare experience. Environments designed to support a patient’s wellbeing result in improved health outcomes. Building upon Australia’s international leadership in contemporary hospita ....Designing for wellbeing: realizing benefits for patients through best practice hospital design. The environmental design of healthcare facilities has been shown to directly affect the wellbeing of patients and their families. Poorly designed environments exacerbate patient anxiety and stress and diminish their healthcare experience. Environments designed to support a patient’s wellbeing result in improved health outcomes. Building upon Australia’s international leadership in contemporary hospital design, this project aims to evaluate, prioritise and strategise the best means for realising benefits of environmental design factors that contribute most significantly to achieving positive outcomes for patients and families. It aims to achieve this through a comprehensive comparative case study analysis of new Australian paediatric hospitals.Read moreRead less
Bayesian back analysis for settlement prediction of soft soils. The settlement of road embankments built on soft soils can take many years which has created additional challenges for road design and construction. Despite many years of experience with the Pacific Highway Upgrade, industry partners have seen many examples where embankments have settled more than expected during construction and after road opening. This causes potential delay delivering projects, ponding, potential aquaplaning and ....Bayesian back analysis for settlement prediction of soft soils. The settlement of road embankments built on soft soils can take many years which has created additional challenges for road design and construction. Despite many years of experience with the Pacific Highway Upgrade, industry partners have seen many examples where embankments have settled more than expected during construction and after road opening. This causes potential delay delivering projects, ponding, potential aquaplaning and unexpected maintenance. This project aims at developing useful tools for industry to better predict the settlement of embankment built on soft soils. The intended outcomes can help to increase the safety level of road transportation system of Australia, reduce construction and maintenance costs.Read moreRead less
Experimental investigation and constitutive modelling of weak rocks subject to mechanical and moisture degradation. The aim of this project is to advance experimental, theoretical and computational bases for the mechanics of weak rocks, and provide scientists and engineers with much-needed predictive tools for quantitative evaluation and assessment of their behaviour in geological settings.

The aim of this project is to advance experimental, theoretical and computational bases for the mechanics of weak rocks, and provide scientists and engineers with much-needed predictive tools for quantitative evaluation and assessment of their behaviour in geological settings. Based on the theoretical results of the research, numerical algorithms will be developed that will assist engineers to apply the findings of the project to geotechnical engineering problems. By incorporating previously neglected aspects in the behaviour of weak rocks such as mechanical, environmental as well as cyclic loading degradation, confidence in the design methods will be increased to the point that costly over designs can be avoided.Read moreRead less
Long-span cold-formed steel portal frames. Novel solutions will be developed for building portal frames in cold-formed steel at effectively twice the span currently available. Economies are derived from using cold-formed steel, which will benefit the end consumer and help the Australian steel industry to maintain its position as preeminent provider of innovative cold-formed steel solutions.

This project will lead to a significant improvement in the serviceability and durability of concrete structures in severe environments.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.
