Development of a Compartment Fire Behaviour Training (CFBT) Database. In recent years, incidents of fire flashover have caused considerable destruction to property and the loss of life. Fire prediction and understanding is an area of significance to both the Australian public and the firefighting profession.

In recent years, incidents of fire flashover have caused considerable destruction to property and the loss of life. Fire prediction and understanding is an area of significance to both the Australian public and the firefighting profession. The NSW Fire Brigade has recently introduced Compartment Fire Behaviour Training (CFBT). To extend this scheme, a database of configurations will be developed using computational modelling, allowing firefighters the ability to experience virtually different situations. Detailed experimental studies will be conducted to validate the numerical model. This database will have use and significance beyond Australia and successful implementation promises reductions in the loss of life and property.Read moreRead less
Foundation remediation using resin injection. The aim of this research project is to explore the application of injected expanded polyurethane resins as a new option for the re-levelling and stabilisation of deflected foundations on reactive clay soils. It will identify the physical and behavioural characteristics of resin-injected reactive clay foundations, in the context of both shallow and deep injection, and will identify any limitations to the applicability of the approach. Based on detaile ....Foundation remediation using resin injection. The aim of this research project is to explore the application of injected expanded polyurethane resins as a new option for the re-levelling and stabilisation of deflected foundations on reactive clay soils. It will identify the physical and behavioural characteristics of resin-injected reactive clay foundations, in the context of both shallow and deep injection, and will identify any limitations to the applicability of the approach. Based on detailed laboratory and field testing, and advanced numerical modelling, the outcome will be the ability to confidently assess various foundation remediation strategies in reactive clay soils, and provide much needed design guidance to the geotechnical profession and building industry.Read moreRead less
Improving thermal performance of low-cost houses for better health of occupants and to reduce costs of temperature control. Recent projects in rural and remote Australian Indigenous communities show that internal house temperatures can vary from accepted temperature ranges that promote well-being, particularly in young children, by up to 20ºC in both summer and winter.
Low-cost housing with poor thermal performance often results in reliance on 'active', often costly-to-run, heating and cooli ....Improving thermal performance of low-cost houses for better health of occupants and to reduce costs of temperature control. Recent projects in rural and remote Australian Indigenous communities show that internal house temperatures can vary from accepted temperature ranges that promote well-being, particularly in young children, by up to 20ºC in both summer and winter.
Low-cost housing with poor thermal performance often results in reliance on 'active', often costly-to-run, heating and cooling appliances.
Measured internal temperatures, energy and water-use data from Indigenous houses will be analysed to demonstrate the link between low-cost house design and poor thermal performance. A methodology and prioritised guidelines for improving temperature control in existing and new low-cost housing will be formulated.

Composite Beams using Fibre Reinforced Concrete (FRC) Profiled Slabs. The Australian construction industry is currently introducing long-span trapezoidal profiled steel sheeting for the composite floor slabs in composite steel-concrete framed buildings, in order improve efficiency and economy. When the ribs in the sheeting are orthogonal to the steel beam (the secondary beam), the integrity of the shear connection between the steel beam and the composite slab is compromised by premature failur ....Composite Beams using Fibre Reinforced Concrete (FRC) Profiled Slabs. The Australian construction industry is currently introducing long-span trapezoidal profiled steel sheeting for the composite floor slabs in composite steel-concrete framed buildings, in order improve efficiency and economy. When the ribs in the sheeting are orthogonal to the steel beam (the secondary beam), the integrity of the shear connection between the steel beam and the composite slab is compromised by premature failures. This project aims to research the innovative use of steel fibre reinforced concrete in these slabs, which has been shown (at UNSW and elsewhere) in other applications to possess superior strength properties when subjected to a variety of loading regimes.Read moreRead less
Strength of two-way steel fibre reinforced composite flooring systems. The construction industry in Australia is introducing efficient and economical long-span profiled steel sheeting for composite flooring systems, and Steel Fibre Reinforced Concrete (SFRC) applications are becoming widespread.

The construction industry in Australia is introducing efficient and economical long-span profiled steel sheeting for composite flooring systems, and Steel Fibre Reinforced Concrete (SFRC) applications are becoming widespread. Australia is a recognised world leader in the research of both composite structures and SFRC. Using SFRC in composite decks to eliminate conventional reinforcement is very efficient and cost-effective, but surprisingly little relevant research aimed at the Australian industry has been reported. Comprehensive design guidance is much needed to advance this technology. This project will give designers confidence and expertise to advance these technologies, while maintaining Australian research and practice in composite structures at the forefront.Read moreRead less
Time-Dependent Response and Deformations of Composite Beams with Innovative Deep Trapezoidal Decks. The construction industry in Australia is introducing efficient and economical long-span trapezoidal profiled steel sheeting for composite flooring systems.

The construction industry in Australia is introducing efficient and economical long-span trapezoidal profiled steel sheeting for composite flooring systems. Australia is a world leader in the research of composite structures. Composite beams undergo deformations because the concrete creeps and shrinks, and because the slab slips relative to the steel joist. Surprisingly little research has addressed these issues collectively; they are of paramount significance with trapezoidal decks and research is much-needed. This research will investigate the interaction of creep, shrinkage and partial interaction in these composite beams, producing valuable design guidance to keep Australian research and practice at the forefront internationally.Read moreRead less
The Characterisation of Fires in Tunnels. A series of 22 fires ranging from 2 megawatt up to 20 megawatt intensity will be set under controlled conditions in unused tunnel facilities, in New South Wales. Instrumentation in the tunnel, donated by the State Rail Authority of New South Wales, will monitor the movement of particulates (smoke). This information is vital to tunnel design, and for passenger life safety. This information will be applicable to all tunnels worldwide.
Residential Air Conditioning, Comfort and Demand Response in Australia. Rapid growth in residential air conditioning (AC) ownership will potentially undermine national energy efficiency and greenhouse reduction targets. Furthermore, residential AC is placing a strain on the national electricity system, especially during heat waves when electricity demand peaks. These AC-driven peak loads occur occasionally each summer, but increasing grid capacity to meet them represents a grossly inefficient in ....Residential Air Conditioning, Comfort and Demand Response in Australia. Rapid growth in residential air conditioning (AC) ownership will potentially undermine national energy efficiency and greenhouse reduction targets. Furthermore, residential AC is placing a strain on the national electricity system, especially during heat waves when electricity demand peaks. These AC-driven peak loads occur occasionally each summer, but increasing grid capacity to meet them represents a grossly inefficient infrastructure investment. This project will generate Australia's most comprehensive data set on exactly how, when, where, and why residential AC systems are being used. The outcomes will provide a solid platform on which national electricity demand management and AC greenhouse-gas mitigation strategies can be designed.Read moreRead less
