This project will investigate the structural behaviour, strength and reliability of innovative veneer based composite structures manufactured from waste hardwood plantation thinning. Unlike sawn timber, these structures have efficient cross-sectional shapes and can be made in sizes currently not available in timber. Yet due to the proportion of natural singularities in the material, the variability in their mechanical properties is not fully understood and their actual strength cannot be accurately predicted. Additionally, their exact structural behaviour and failure modes require attention. This project aims to fill these gaps in knowledge and ultimately establish probability-based limit state design criteria for these sections.Read moreRead less
Hybrid steel-framed structural systems for mid-rise buildings. The project aims to develop solutions for lightweight structural systems. Hybrid steel structures are those constructed from a mixture of conventional hot-rolled steel sections and tubes combined with lightweight cold-formed steel structural members. There is an increasing need to provide prefabricated structural systems that are highly constructible and modular in mid-rise (5–10 storeys) residential apartment and commercial building ....Hybrid steel-framed structural systems for mid-rise buildings. The project aims to develop solutions for lightweight structural systems. Hybrid steel structures are those constructed from a mixture of conventional hot-rolled steel sections and tubes combined with lightweight cold-formed steel structural members. There is an increasing need to provide prefabricated structural systems that are highly constructible and modular in mid-rise (5–10 storeys) residential apartment and commercial buildings. The major problem in producing efficient hybrid systems is the connections between the hot-rolled framing members and the lightweight cold-formed members. The main aim of the project is to carry out experimental and theoretical research into the hybrid connections. The expected outcomes of the research are more efficient and standardised structural connections and systems.Read moreRead less
Cold-rolled Aluminium Structural Members and Systems. BlueScope Permalite has recently demonstrated that it is possible to produce aluminium structural sections by roll-forming. This presents a faster and less energy consuming method of production than conventional extrusion. Through experiments and numerical simulations, the project aims to develop guidelines for the design of single members and complete structural systems in cold-rolled aluminium. The project intends to quantify the strength e ....Cold-rolled Aluminium Structural Members and Systems. BlueScope Permalite has recently demonstrated that it is possible to produce aluminium structural sections by roll-forming. This presents a faster and less energy consuming method of production than conventional extrusion. Through experiments and numerical simulations, the project aims to develop guidelines for the design of single members and complete structural systems in cold-rolled aluminium. The project intends to quantify the strength enhancements achievable by the cold-rolling process and devise guidelines for determining the strength of cold-rolled aluminium sections and systems, considering the prevalent buckling modes for C- and Z-sections, their interactions and the effect of gradual yielding.Read moreRead less

Behaviour of novel FRP-timber composite thin-walled structural members. This project aims to investigate the structural behaviour of innovative hybrid Fibre Reinforced Polymer - Timber Composite (FRPTC) sections manufactured from small 'sawlog' timber. These FRPTC sections are made by taking advantage of the orthotropic material properties and, unlike sawn timber, these structures have efficient cross sectional shapes and can be made easily in different sizes to match the requirements.

This project aims to investigate the structural behaviour of innovative hybrid Fibre Reinforced Polymer - Timber Composite (FRPTC) sections manufactured from small 'sawlog' timber. These FRPTC sections are made by taking advantage of the orthotropic material properties and, unlike sawn timber, these structures have efficient cross sectional shapes and can be made easily in different sizes to match the requirements. Even though preliminary studies have shown promising results, behaviour of these FRPTC sections are not yet fully understood. This project aims to investigate the behaviour of these novel FRPTC sections and to develop numerical models to allow wide usage of these sections.Read moreRead less

Achieving structural morphing via functionalising nonlinear buckling. This project aims to develop a general framework to analyse and design functional components of buildings and structures, where they change shapes (morphing) by buckling. Australian buildings consume 20% of the nation’s total energy production on heating and cooling, and projected population increases are likely to increase energy demands. The shape changes are optimised, e.g. to reduce energy consumption by minimising solar r ....Achieving structural morphing via functionalising nonlinear buckling. This project aims to develop a general framework to analyse and design functional components of buildings and structures, where they change shapes (morphing) by buckling. Australian buildings consume 20% of the nation’s total energy production on heating and cooling, and projected population increases are likely to increase energy demands. The shape changes are optimised, e.g. to reduce energy consumption by minimising solar radiation loads or maximising natural air ventilation. The project expects to develop building technology solutions to reduce Australia's energy consumption, and provide domestic and global market opportunities in the high-tech manufacturing sector.Read moreRead less

Buckling capacity of high-strength steel flexural members. This project aims to investigate the capacity of high-strength steel (HSS) flexural members by undertaking physical tests and numerical simulations, and proposes to craft innovative overarching design guidance for them within a paradigm of Design by Advanced Analysis. HSS structures are significant as they are lighter than their mild steel counterparts and so use less material, with a much lower carbon footprint. Modern metallurgical pro ....Buckling capacity of high-strength steel flexural members. This project aims to investigate the capacity of high-strength steel (HSS) flexural members by undertaking physical tests and numerical simulations, and proposes to craft innovative overarching design guidance for them within a paradigm of Design by Advanced Analysis. HSS structures are significant as they are lighter than their mild steel counterparts and so use less material, with a much lower carbon footprint. Modern metallurgical process can produce HSS of Grade 1000 Megapascals or higher, but there is no specific structural code governing their design. Surprisingly little research has been reported on HSS flexural members which fail by lateral buckling, and this is the focus of the project, filling the gap needed to produce an advanced design standard.Read moreRead less
Durability and debonding resistance of composite based strengthening techniques for deteriorated structures. Australia has many concrete structures exposed to aggressive environments that are deteriorating prior to their intended design life due to durability issues. Externally bonded fibre reinforced polymer composite applications are emerging as a method of structural rehabilitation. This project will provide safe and reliable strengthened structures.
Hybrid stainless-carbon steel composite beam-column joints at ambient and elevated temperatures. This project will consider the behaviour of hybrid stainless-carbon steel composite beam-column joints at ambient and elevated temperatures. By incorporating into potential design codes, the results can promote the application of stainless steel in structures, thereby increasing Australia's maintenance capability of structures.
