Minimisation of damage to residential structures due to ground movement. In Australia some 150,000 new houses are built every year with a total value of approximately $40 billion; making it one of the most significant industries affecting consumers and industries. With a quadrupling of the cost of building new houses in the last 20 years, an increase in the levels of expectations of owners, a high rate of reported damage in new and existing houses, and predications of worsening conditions under ....Minimisation of damage to residential structures due to ground movement. In Australia some 150,000 new houses are built every year with a total value of approximately $40 billion; making it one of the most significant industries affecting consumers and industries. With a quadrupling of the cost of building new houses in the last 20 years, an increase in the levels of expectations of owners, a high rate of reported damage in new and existing houses, and predications of worsening conditions under climate change scenarios; there is an urgent need to evaluate the causes of damage. The outcomes from this project will assist in minimising damage to houses from ground movement and in adopting new performance-based design methods for new homes to better match owner expectations. This will lead to cost effective and innovative solutions to meet adverse conditions.Read moreRead less

An innovative structural system utilising sandwich panel technology and shell action has recently emerged. These aesthetically pleasing curved structures are durable and spacious with fast construction time. They have residential and commercial applications and have attracted considerable local and overseas interest. There are no definitive procedures for their analysis and design and their behaviour is complex involving many variables such as sandwich layer interaction, shape, openings, structural action, etc. This project will generate fundamental knowledge on their behaviour over a range of properties and operating conditions and develop guidelines to ensure safe and economical design, bringing economic benefits to Australia.Read moreRead less
Rational lateral-bracing design for steel-framed domestic structures. For the 150,000 new Australian houses built annually to remain safe, despite expected increases in structural loading due to climate change, rational design approaches are desperately needed. This project will provide the industry with the necessary tools to develop optimised and innovative solutions to brace houses for extreme events and yet maintain affordability.
Long-span cold-formed steel portal frames. Novel solutions will be developed for building portal frames in cold-formed steel at effectively twice the span currently available. Economies are derived from using cold-formed steel, which will benefit the end consumer and help the Australian steel industry to maintain its position as preeminent provider of innovative cold-formed steel solutions.
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.
Fire resistance of complex light gauge steel framed wall systems. This project aims to investigate the thermal and structural behaviour of high-strength Light gauge Steel Framed (LSF) wall systems when exposed to fire, and develop a generic model for predicting fire resistance levels of all LSF wall systems. Plasterboard-lined LSF walls are increasingly used as cost-effective load-bearing walls in low and mid-rise buildings worldwide. This has required new wall designs with complex steel stud wa ....Fire resistance of complex light gauge steel framed wall systems. This project aims to investigate the thermal and structural behaviour of high-strength Light gauge Steel Framed (LSF) wall systems when exposed to fire, and develop a generic model for predicting fire resistance levels of all LSF wall systems. Plasterboard-lined LSF walls are increasingly used as cost-effective load-bearing walls in low and mid-rise buildings worldwide. This has required new wall designs with complex steel stud wall configurations, but their fire resistance is not understood. This project will provide validated fire resistance data and fire design methods for a proposed national Fire Design Handbook and steel design codes, enabling more widespread, safer use of these walls. This will benefit the Australian steel industry, the construction industry and the community.

LSF systems are increasingly used in homes and offices. The project plans to investigate fundamental thermal, structural and energy performances of LSF walls and their components using experimental and numerical studies. It plans to develop enhanced plasterboards, insulations and innovative composite panels using suitable nanomaterials, chemical additives, fillers and phase-change materials and use these with innovative wall configurations to significantly improve the fire and energy performance of LSF walls. The new wall systems may increase occupant comfort and safety, reduce business losses in fires, and lead to low-energy buildings.Read moreRead less
Bearing capacities of innovative LiteSteel beams and their floor systems. This project will develop accurate bearing capacity design models for the new LiteSteel beams (LSB) to enable innovative and safe applications of LSBs in various flooring systems in buildings. Improved LSB floor systems will also be developed. This will enable expansion of the worldwide market for LSB products and systems by the industry partner.
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. The joining consists of screws, or similar fasteners, placed intermittently along the member.

Safe shelters are needed within residential, school and commercial building systems to prevent the loss of lives during natural disasters. This project aims to understand how the fire, cyclone and earthquake resistance of shelters can be increased by using a new cold-formed and rivet fastened hollow flange section as studs and joists within the lightweight steel frame wall, and floor systems with superior configurations that are lined with thin steel sheet and thermally superior boards. Experimental and numerical studies will be used to enhance our understanding of these novel and more complex systems and develop safer shelter systems at low cost. They can also be used in many other applications based on the emerging modular building concept.Read moreRead less
