Connections for hybrid steel-timber-concrete structures. Connections play a vital role in overall performance, reliability, and adaptability of civil structures. This project aims to develop innovative, easy to fabricate and efficient connections for hybrid structural systems that fully exploit advantages of steel, concrete and engineered timber to reduce the self-weight, cost and negative environmental impact and enhance opportunities for deconstruction, reusing and upgrading of the structures. ....Connections for hybrid steel-timber-concrete structures. Connections play a vital role in overall performance, reliability, and adaptability of civil structures. This project aims to develop innovative, easy to fabricate and efficient connections for hybrid structural systems that fully exploit advantages of steel, concrete and engineered timber to reduce the self-weight, cost and negative environmental impact and enhance opportunities for deconstruction, reusing and upgrading of the structures. Structural performance of the connections will be assessed by laboratory testing and advanced numerical modelling. Comprehensive knowledge on stiffness, strength, and ductility and world-first provisions for safe and cost-effective design of the hybrid steel-timber-concrete structures are generated.Read moreRead less
Torsion in innovative timber composite floors. Application of lightweight sustainably sourced timber panels combined with steel beams or reinforced concrete slabs in composite floors has the potential to significantly improve the speed and efficiency and reduce the carbon and energy footprint of the construction industry. This project aims to produce world first benchmark experimental data and advanced numerical and simple analytical models required for efficient, yet safe and reliable analysis ....Torsion in innovative timber composite floors. Application of lightweight sustainably sourced timber panels combined with steel beams or reinforced concrete slabs in composite floors has the potential to significantly improve the speed and efficiency and reduce the carbon and energy footprint of the construction industry. This project aims to produce world first benchmark experimental data and advanced numerical and simple analytical models required for efficient, yet safe and reliable analysis and design of timber-concrete and steel-timber composite floors subjected to complex 3-dimensional loading scenarios that involve combinations of torsion, bending and shear. The outcomes of this project are expected to promote innovation and advance knowledge in the field of structural mechanics.Read moreRead less
Thermal-induced unilateral plate buckling of concrete pavements: design and evaluation. The project addresses the upheaval buckling of concrete pavements, which is caused by increasingly frequent heat spells. It will consider both the vulnerability assessment of existing pavements, and the design of new pavements made from low-carbon geopolymer concretes (which are lighter than conventional pavements) against upheaval buckling.
Composite steel-timber structural system. This project aims to deliver a novel composite steel–timber system that alleviates many of the environmental concerns of the industry, while improving efficiency by using lighter materials. It aims to develop a unique composite system comprised of steel I-section beams and prefabricated timber slabs, with shear connection being provided by bolting or screws. The project plans to assess the structural system experimentally and numerically, and to craft gu ....Composite steel-timber structural system. This project aims to deliver a novel composite steel–timber system that alleviates many of the environmental concerns of the industry, while improving efficiency by using lighter materials. It aims to develop a unique composite system comprised of steel I-section beams and prefabricated timber slabs, with shear connection being provided by bolting or screws. The project plans to assess the structural system experimentally and numerically, and to craft guidelines for the safe and efficient design of these members. The novel lightweight composite system would enhance the speed of construction, allow for deconstructability and reuse and, because plantation timber sequestrates carbon dioxide, have a low carbon footprint.Read moreRead less

Summary
An Innovative and Advanced Systems Approach for Full Life-Cycle, Low-Emissions Composite and Hybrid Building Infrastructure. This project will develop a 'green' sustainable composite steel-concrete building frame system that reduces greenhouse gas emissions throughout the life-cycle of building construction, usage and deconstruction. It will eliminate the use of ordinary Portland cement, which is a major carbon dioxide producer, by using geopolymer concrete made from fly-ash, and will use econom ....An Innovative and Advanced Systems Approach for Full Life-Cycle, Low-Emissions Composite and Hybrid Building Infrastructure. This project will develop a 'green' sustainable composite steel-concrete building frame system that reduces greenhouse gas emissions throughout the life-cycle of building construction, usage and deconstruction. It will eliminate the use of ordinary Portland cement, which is a major carbon dioxide producer, by using geopolymer concrete made from fly-ash, and will use economic thin-walled, high-strength steel sections. Deconstructability is provided through bolted joints and by using tensioned bolts as shear connectors between the steel skeleton and concrete flooring. This project is underpinned by the extensive background of the candidate, and provides a very timely solution to a major contemporary engineering challenge facing Australia.Read moreRead less
Composite Structures of High-Strength Steel and Concrete. This project plans to investigate the use in building frames of composite steel-concrete members that use high-strength steel (HSS) instead of mild steel (MS). HSS is finding increased use in construction, and HSS has a much greater strength-to-weight ratio than MS, leading to lighter composite structures, less material usage and smaller foundations. Overall, this reduces the cost and carbon footprint of steel-framed buildings. The invest ....Composite Structures of High-Strength Steel and Concrete.

HSS is finding increased use in construction, and HSS has a much greater strength-to-weight ratio than MS, leading to lighter composite structures, less material usage and smaller foundations. Overall, this reduces the cost and carbon footprint of steel-framed buildings. The investigation is planned to involve physical testing, numerical studies, developing structural models and crafting design guidance for T-beams, columns and joints. The major intended outcome of the project is design guidance that will support the expanded use of HSS.Read moreRead less
