This project aims to develop a next-generation building system integrated with robotic construction, using intelligent interlocking block units with hazard resistance, and sustainable engineered recycled plastic waste materials. It spans from discovery of using recycled waste materials to development of analysis and design methods for a new interlocking structure, as well as mitigation measures for blast resistance. The successful implementation of this project will result in a technically, financially and environmentally sound structure form for the next-generation of robotic construction. This should lead to a revolution in construction that will substantially improve construction efficiency, quality and affordability.Read moreRead less
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
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.

Retrofitted brick masonry buildings - are they reliable over the long term? The aim of this project is to investigate the long-term reliability of a new earthquake strengthening technique for brick buildings. The technique involves the use of fibre reinforced polymer (FRP) strips as reinforcement for brick walls and has been shown to give substantial instantaneous strength increases. However, no research has been undertaken to ensure that the improved strength is sustained over the remaining lif ....Retrofitted brick masonry buildings - are they reliable over the long term? The aim of this project is to investigate the long-term reliability of a new earthquake strengthening technique for brick buildings. The technique involves the use of fibre reinforced polymer (FRP) strips as reinforcement for brick walls and has been shown to give substantial instantaneous strength increases. However, no research has been undertaken to ensure that the improved strength is sustained over the remaining life of the building. The only related research involves reinforced concrete which suggests that a reduction of at least 33 per cent could be expected. Hence, this project will quantify the long-term strength of FRP reinforced brickwork to enable engineers to safely apply this new cost-effective retrofit technique.Read moreRead less

This project will develop new and innovative ways of constructing steel structures using the rising factory concept. The rising factory is a 10 storey enclosure where the final high-rise building is safely constructed within a watertight envelope which rises as the building progresses. The project will perform the necessary research to make possible high-rise steel structural systems consisting of hot-rolled (heavy gauge) and cold-formed (light gauge) steel structural members and connections which can be used in the rising factory. The main benefits of the rising factory are the waterproof construction environment and the substantially increased safety as a result of no external cranes.

The study will provide vital data needed for for adoption by engineers and Standards bodies.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
