Ultra-high strength (UHS) steel tubes are currently used mainly in the vehicle industry due to their high strength and light weight. This project aims to enable the building of more resilient and sustainable infrastructure by utilising these UHS steel tubes in double-skin composite tubular construction. To date there has been little work to understand the effects of fire, earthquake and impact related incidents on these structures. This project aims to access unique testing facilities for full size impact and fire testing and the state-of-the-art hybrid testing simulation. It is expected to increase the competitiveness of the Australian manufacturing industry by overcoming the bottleneck in the manufacture of steel sections.Read moreRead less

Country Girlhood: the meaning and experience of girlhood in rural and regional Australia. What meanings does Australian country life impose on or generate for girls, and how have these helped define both country life and girlhood in Australia? Looking at the experience of growing up in rural and regional (ie. non-metropolitan) Australia, and how governments and communities have sought to respond to and define it, this project considers how country girlhood has interacted with social policy and o ....Country Girlhood: the meaning and experience of girlhood in rural and regional Australia. What meanings does Australian country life impose on or generate for girls, and how have these helped define both country life and girlhood in Australia? Looking at the experience of growing up in rural and regional (ie. non-metropolitan) Australia, and how governments and communities have sought to respond to and define it, this project considers how country girlhood has interacted with social policy and other influences, and as a particular conjunction of age, gender, location, and community. Is there such a thing as Australian country girlhood, and how has it been shaped by or helped form Australian ways of life?Read moreRead less
Control of cracking caused by early-age contraction of concrete. An extensive program of laboratory testing will be undertaken to quantify the extent of cracking in concrete walls and slabs due to early-age cooling and shrinkage of concrete. Analytical models for quantifying restraint in walls and slabs will be developed, as will methods for the prediction and control of crack widths and crack spacings.
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. The ease of joining encourages innovation in forming versatile new built-up section shapes in expanding areas of application. The project will provide guidelines and numerical tools for the efficient structu ....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. The ease of joining encourages innovation in forming versatile new built-up section shapes in expanding areas of application. The project will provide guidelines and numerical tools for the efficient structural design of built-up sections through experimental and theoretical research, studying the new failure modes pertaining to built-up sections, the increase in strength achievable from composite action and the optimum arrangement of fasteners.

A mix design approach to reduce early-age thermal cracking of concrete. The aim of this project is to determine the fundamental mechanics of early age thermal cracking in mass concrete elements and in members with high cement contents, and to develop a tool to predict early age cracking. Early age thermal cracking in concrete due to heat of hydration and thermal gradients is a major engineering problem and is undesirable for durability and structural performance, as well as aesthetics and projec ....A mix design approach to reduce early-age thermal cracking of concrete. The aim of this project is to determine the fundamental mechanics of early age thermal cracking in mass concrete elements and in members with high cement contents, and to develop a tool to predict early age cracking. Early age thermal cracking in concrete due to heat of hydration and thermal gradients is a major engineering problem and is undesirable for durability and structural performance, as well as aesthetics and project economics. The research outputs include new theories and relationships from which advanced engineering models will be derived that will support improved design and construction of mass concrete elements.Read moreRead less
Life-cycle cost and emission analyses of green-building implementation. In Australia, the annual average temperature has increased 0.9 degrees Celsius since 1910. Residential and commercial building sectors produce about 23 per cent of the national greenhouse-gas emissions.

In Australia, the annual average temperature has increased 0.9 degrees Celsius since 1910. Residential and commercial building sectors produce about 23 per cent of the national greenhouse-gas emissions. This project critically evaluates the cost effectiveness and greenhouse-gas emissions of green-building implementation in Australia. This will examine methods to lower cost and greenhouse-gas emissions from green-building implementation. A new high-tech scoring model is expected to be developed to identify cost-effective and low-greenhouse-gas-emissions methods to achieve specific green-star status for the Australian building and construction industries.Read moreRead less

National drop weight impact testing facility:
The national drop weight impact testing facility aims to enable dynamic tests on geo- and construction materials and systems. This facility aims to provide state-of-the-art technology to observe the real-time behaviour of elements and sub-assemblies under combined quasi-static and impact loading. Understanding material behaviour under dynamic loading is essential in dealing with many engineering problems. The facility may advance understanding of the fundamental behaviour of critical infrastructure exposed to impact loading and will foster innovations in design and construction. Applications may include improvement of the structural safety of infrastructure including railway networks, tunnels and bridges, and also the development of cost-effective and environmentally friendly building and construction materials.

This project will close the knowledge gap of how shallow foundations perform in variably saturated soils. It will integrate expertise in unsaturated soil mechanics, theory of elasto-plasticity, numerical modelling, limit analysis and experimental investigation. It will achieve a rigorous understanding of footings founded on unsaturated soils subjected to monotonic loading using a recently developed experimental testing facility, and analyses using finite elements, the method of characteristics and zero extension line theory. Impact and adoption in industry will be direct through world first design tools which incorporate the influence of suction on bearing capacity, settlement and safety.Read moreRead less
Partner choice and sexual behaviour among gay and bisexual men. Current social and political debate about what constitutes legitimate relationships hinge on the status of same-sex relationships. Partner choice is key to understanding individuals' sexual behaviour and the relationships they develop in response. Yet gay and bisexual men's (GBM) sexual partner choices have not been researched.

Current social and political debate about what constitutes legitimate relationships hinge on the status of same-sex relationships. Partner choice is key to understanding individuals' sexual behaviour and the relationships they develop in response. Yet gay and bisexual men's (GBM) sexual partner choices have not been researched. The project aims to describe types of partner choices among GBM and how these affect the specific sex practices, including risk behaviours, in which they engage and their style and pattern of relationships. It also aims to identify the contextual and individual factors associated with these choices. This evidence is expected to inform current debate and help improve health promotion and relationship support work among GBM.Read moreRead less
