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.
Light steel roof and wall systems under combined wind and bushfire actions. The project aims to investigate the complex behaviour of light cold-formed-steel roof and wall systems involving localized failures under the combined action of wind and bushfire using wind suction tests at elevated temperatures combined with advanced numerical modelling. It will generate new knowledge of the behaviour and strength of cold-formed-steel roof and wall systems under bushfire conditions.

The project aims to investigate the complex behaviour of light cold-formed-steel roof and wall systems involving localized failures under the combined action of wind and bushfire using wind suction tests at elevated temperatures combined with advanced numerical modelling. It will generate new knowledge of the behaviour and strength of cold-formed-steel roof and wall systems under bushfire conditions. Expected outcomes include new design models for wind, bushfire and cold-formed-steel Standards. This will significantly improve the bushfire safety of buildings, since non-combustible steel roof and wall systems are used as building envelopes in bushfire prone areas, but are not designed to withstand recently discovered bushfire-enhanced winds.Read moreRead less

Summary
Novel Shelters Using Sheathed Cold–formed Steel Framing Systems. 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 li ....Novel Shelters Using Sheathed Cold–formed Steel Framing Systems. 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
Development of efficient, robust and architecturally-flexible structural systems using innovative blind-bolted connections. The aim of the proposed project is to develop structural systems that have sufficient stiffness, strength, and ductility to withstand code-specified loads and that will be competitive in the marketplace. The development of demonstrable cost-effective structural systems is essential if these types of systems are to be widely adopted in practice, thus allowing Australian manu ....Development of efficient, robust and architecturally-flexible structural systems using innovative blind-bolted connections. The aim of the proposed project is to develop structural systems that have sufficient stiffness, strength, and ductility to withstand code-specified loads and that will be competitive in the marketplace. The development of demonstrable cost-effective structural systems is essential if these types of systems are to be widely adopted in practice, thus allowing Australian manufacturers of blind bolts and steel tubes to achieve a greater market share.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.
Analysis and design of midrise built-up cold-formed steel structures. The project will develop an analytical and computational basis for designing midrise buildings in cold-formed steel. It will enable solutions with high column capacities and high lateral load resistance to be realised by using built-up sections, thus overcoming the current barrier to constructing buildings up to 10 storeys from cold-formed steel and enabling green, fully recyclable and rapidly constructed buildings to be achie ....Analysis and design of midrise built-up cold-formed steel structures.

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
