The behaviour and design of composite columns coupling the benefits of high strength steel and high strength concrete for large scale infrastructure. This project will involve the development of a novel structural column system which will be more efficient, robust and require less maintenance than current systems. The outcomes will involve improved design methodologies which will enable large scale infrastructure to be enhanced and will involve the use of materials which improve sustainability.
Mixed Mode Torsion-Shear-Bending Failure in SFRC Elements . In 2017 and 2018 the Australian Standards for the design of concrete bridges and structures were released; these are some of the first in the world, to include design procedures for steel fibre reinforced concrete (SFRC) in a comprehensive way. While rules have been introduced for shear and bending of SFRC girders, the rules exclude the use fibres to carry torsional moments. This study investigates the torsion-bending-shear interaction ....Mixed Mode Torsion-Shear-Bending Failure in SFRC Elements .

While rules have been introduced for shear and bending of SFRC girders, the rules exclude the use fibres to carry torsional moments. This study investigates the torsion-bending-shear interaction performance of SFRC members. The study will provide vital data needed for for adoption by engineers and Standards bodies.Read moreRead less
Behaviour of ultra-high strength double-skin composite tubular construction. Ultra-high strength (UHS) steel tubes are currently used mainly in the vehicle industry due to their high strength and light weight. This project aims to enable the building of more resilient and sustainable infrastructure by utilising these UHS steel tubes in double-skin composite tubular construction.

This project aims to enable the building of more resilient and sustainable infrastructure by utilising these UHS steel tubes in double-skin composite tubular construction. To date there has been little work to understand the effects of fire, earthquake and impact related incidents on these structures. This project aims to access unique testing facilities for full size impact and fire testing and the state-of-the-art hybrid testing simulation. It is expected to increase the competitiveness of the Australian manufacturing industry by overcoming the bottleneck in the manufacture of steel sections.Read moreRead less
Composite tubular construction subject to impact and blast loading. This project will advance the knowledge of composite tubular members and connections under impact and blast loading. It will provide confident design methodology against impact and blast loading for buildings designated as prominent targets or items of critical infrastructure, to save lives and reduce losses.
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. It aims to offer desirable properties, such as being light-weight, easy to construct, economical, recy ....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. 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

Summary
Free-forming and function-integrated composite structures for future green building construction. The free expression of structure in space is a constant pursuit for architects while being a complex task for engineers. Fibre-reinforced polymer sandwiches provide an ideal way to address this challenge. This project aims to develop a novel free-forming system using such elements and explore their thermal-energy-light multifunctional integration.
Development of Novel Metaconcrete to Resist Impulsive Loads. This project aims to develop innovative metaconcrete for structural protection by utilising the concept of phononic crystals and metamaterials which has been recently developed by physicists. Traditional construction materials are used in new structural forms to mitigate dynamic loading effects by exploiting the unique characteristics of the proposed metaconcrete.

This project aims to develop innovative metaconcrete for structural protection by utilising the concept of phononic crystals and metamaterials which has been recently developed by physicists. Traditional construction materials are used in new structural forms to mitigate dynamic loading effects by exploiting the unique characteristics of the proposed metaconcrete. Theoretical, numerical and experimental methods will be used to derive the best performing metaconcrete and verify its static and dynamic load resistant capacities. The expected outcomes of the project will lead to innovative extreme-loading resistant designs and provide significant benefit to the Australian construction industry, general public and economy.Read moreRead less
Built-up cold-formed steel structures. The building industry is seeing a rapid uptake of joining two or more cold-formed steel sections to form large built-up sections with high carrying capacities.
