Direct strength method of design of simple and complex thin-walled shapes for combined actions. The Direct Strength Method project will allow structural design engineers, and companies manufacturing cold-formed steel building products to innovate more widely. It will enhance the Australian and American standards for cold-formed steel design improving safety in building structures.
Interaction of Local and Distortional Buckling in Thin-Walled High Strength Steel Sections. Recent research at the University of Sydney has shown that the local and distortional buckling modes in thin-walled high strength steel sections may have adverse interaction. Cold-Formed steel sections of this type are used in residential construction, ceiling systems, partitioning systems in offices and other light gauge applications. The project will develop mathematical models of the interaction beha ....Interaction of Local and Distortional Buckling in Thin-Walled High Strength Steel Sections. Recent research at the University of Sydney has shown that the local and distortional buckling modes in thin-walled high strength steel sections may have adverse interaction. Cold-Formed steel sections of this type are used in residential construction, ceiling systems, partitioning systems in offices and other light gauge applications. The project will develop mathematical models of the interaction behaviour of sections of this type for a wide range of section geometries. A major outcome will be design methods which accurately quantify the interaction behaviour based on the models. Testing will be undertaken to support the theoretical developments and to calibrate the design models.Read moreRead less
Developing auxetic composite system for protective engineering applications. This project intends to explore the possibilities of extending the latest developments in auxetic technologies to the protective design of engineering structures. Auxetic materials become thicker perpendicular to the applied force when stretched. Specifically, the project plans to develop a novel auxetic composite system with a focus on protecting civil and defence infrastructure from extreme loads. It is expected that ....Developing auxetic composite system for protective engineering applications. This project intends to explore the possibilities of extending the latest developments in auxetic technologies to the protective design of engineering structures. Auxetic materials become thicker perpendicular to the applied force when stretched. Specifically, the project plans to develop a novel auxetic composite system with a focus on protecting civil and defence infrastructure from extreme loads. It is expected that the system’s superior energy dissipating capability will broaden its application beyond civil infrastructure, such as armoured vehicles, protective sports gear and body armour. The project also plans to develop a multiscale numerical modelling and topological optimisation framework to accelerate the adoption of this advanced composite system.Read moreRead less
Reliability and full-range analysis of joints in steel frameworks. The project has two main components, namely to establish a mechanics-based nonlinear model for representing joints in structural analyses, and a reliability framework at system level that considers randomness in the strength and behaviour of both members and joints. As its main aim, the project aims to pave the way for introducing computer-based direct design of steel frames in the structural engineering community, thus obviating ....Reliability and full-range analysis of joints in steel frameworks. The project has two main components, namely to establish a mechanics-based nonlinear model for representing joints in structural analyses, and a reliability framework at system level that considers randomness in the strength and behaviour of both members and joints. As its main aim, the project aims to pave the way for introducing computer-based direct design of steel frames in the structural engineering community, thus obviating the need for checking member and joint strengths to a structural standard. The direct design approach is more accurate, economical and faster than current design practice, provides more uniform structural system reliability, and encourages innovation in structural and architectural forms.Read moreRead less
System reliability-based criteria for designing steel structures by advanced analysis. The aim of the project is to develop a new system-based criterion for designing steel structures using advanced analysis methods. The outcome of the research will help industry to design safer and more economic steel structures, thus enabling the profession to stay competitive in the national and international marketplace.
Understanding the performance of cold-formed steel frame wall systems in fires to design for superior fire resistance. This project will develop new light gauge steel frame (LSF) wall systems with superior fire resistance rating and associated design rules to enable innovative and safe applications of these wall systems in various building applications. This will enable expansion of the worldwide market for LSF wall systems by the industry partner.
Coupled service and ultimate behaviour of high strength composite columns. This project aims to improve the coupled service and strength load behaviour of high strength composite columns used in building and bridge infrastructure. Taller and longer buildings and bridges need efficient and safe material. Australian Standards for concrete and steel now allow higher strength materials of 100 and 690 MPa.

This project aims to improve the coupled service and strength load behaviour of high strength composite columns used in building and bridge infrastructure. Taller and longer buildings and bridges need efficient and safe material. Australian Standards for concrete and steel now allow higher strength materials of 100 and 690 MPa. This project will consider coupled service and strength load issues incorporating time-dependent effects and ductility, and extend the range of concrete and steel strengths to 150 and 960 MPa for world-class heavy infrastructure. This project is expected to improve the safety and economy of tall buildings, bridges and large infrastructure.Read moreRead less
