Unified analysis of steel and composite frame structures subjected to static, thermal, earthquake and blast loading. Understanding the science of extreme loading on engineering structures is essential for their design, and increasingly with terrorism threats there is a need for assessment and strengthening of identified vulnerable critical infrastructure. Rational design paradigms have not yet matured for extreme load scenarios, and they are much-needed to protect life, limb and amenity. Austral ....Unified analysis of steel and composite frame structures subjected to static, thermal, earthquake and blast loading. Understanding the science of extreme loading on engineering structures is essential for their design, and increasingly with terrorism threats there is a need for assessment and strengthening of identified vulnerable critical infrastructure. Rational design paradigms have not yet matured for extreme load scenarios, and they are much-needed to protect life, limb and amenity. Australian research is at the forefront in steel and composite structures, and this project will strengthen Australia's positioning in the discipline by developing transparent design and assessment procedures from an efficient algorithm that delivers hands-on guidance for engineering practitioners.Read moreRead less
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. 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. Surprisingly little research has address ....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. 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
Advanced analysis, behaviour and design of steel and steel-concrete composite engineering structures subjected to elevated temperatures. This Fellowship aims to develop a consistent advanced nonlinear method for the analysis and behaviour of steel and composite building frames that are subjected to elevated temperatures.

This Fellowship aims to develop a consistent advanced nonlinear method for the analysis and behaviour of steel and composite building frames that are subjected to elevated temperatures. There is widespread feeling amongst practitioners that, in the absence of reliable techniques for verifying this behaviour, the regulatory need for fire protection of steel is excessive, and the high expense involved in providing this protection is leading structural steel being rejected in engineering design. This growing trend is leading to a potential downturn in structural steel production, which has serious economic and social ramifications on Australian communities whose fabric is centred on this activity.Read moreRead less

Long Term Behaviour Of Composite Steel-Concrete Beams And Its Effect On Composite Dynamic Response. Composite steel-concrete construction has proven to be a most prolific area of research over the last few decades with Australian researchers at the forefront in the field internationally. Despite this and the great significance of the problem to the Australian building industry (in 2000-2001 alone Australia spent 17.5 billion dollars on heavy engineering infrastructure development), there appears ....Long Term Behaviour Of Composite Steel-Concrete Beams And Its Effect On Composite Dynamic Response. Composite steel-concrete construction has proven to be a most prolific area of research over the last few decades with Australian researchers at the forefront in the field internationally. Despite this and the great significance of the problem to the Australian building industry (in 2000-2001 alone Australia spent 17.5 billion dollars on heavy engineering infrastructure development), there appears to be no systematic study of time effects, such as creep and shrinkage, on the static and dynamic response of composite beams. This project will explore these phenomena, both theoretically and experimentally, leading to development of valuable theoretical models and design aids for practicing engineers.Read moreRead less
