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
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. 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, b ....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. 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. 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.

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
Behaviour of post-tensioned composite steel-concrete slabs. Post-tensioned composite steel-concrete slabs represent an attractive and novel form of construction capable of combining the advantages of the two most commonly used flooring systems in the Australian building industry which consist of post-tensioned slabs in the case of concrete structures and of composite slabs for steel structures. The advantages of this novel system cannot be exploited as yet as no design guidelines are currently a ....Behaviour of post-tensioned composite steel-concrete slabs. Post-tensioned composite steel-concrete slabs represent an attractive and novel form of construction capable of combining the advantages of the two most commonly used flooring systems in the Australian building industry which consist of post-tensioned slabs in the case of concrete structures and of composite slabs for steel structures. The advantages of this novel system cannot be exploited as yet as no design guidelines are currently available. The proposed research team embraces all the construction building industry and will investigate the structural behaviour of post-tensioned composite slabs, producing valuable design guidance to keep Australian research and practice at the forefront internationally.Read moreRead less
Optimisation of Building Structures Considering Wind Loading. Wind loading is a dominant factor that should be carefully considered and resourcefully exploited in the design of building structures.

Wind loading is a dominant factor that should be carefully considered and resourcefully exploited in the design of building structures. The ever-taller buildings proposed around the world have presented a major challenge and opportunity in the pursuit of new techniques and materials. The proposed research will improve the competitiveness and productivity of the Australian building design industry by establishing a cutting-edge computer-automated design tool for creating innovative building systems that can resist wind loading effectively and efficiently.

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.

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
