The infrastructure in Australia and beyond has long suffered from deterioration due to corrosion of steel reinforcement/sections. This project will address this problem by investigating a new form of hybrid columns, namely fibre reinforced polymer confined concrete-encased steel composite columns. The idea of combining a fibre reinforced polymer-confined concrete and a steel section not only makes the column a durable and ductile alternative to steel/concrete columns, but also makes them an efficient method for retrofitting or strengthening deteriorated steel columns. This project will study the structural behaviour of fibre reinforced polymer confined concrete-encased steel composite columns, and develop design methods to pave the way towards their wide practical applications.

This project aims to develop a new generation of concrete-filled steel tubular (CFST) columns free from reinforcement by using fly ash-based fire-resistant concrete. In Australia, existing CFST columns use a large amount of internal reinforcement to maintain the structural integrity under fire attack. Through the generation of CFST columns with superior fire resistance rating and associated design rules to enable innovative and saf ....Development of next generation fire-resistant composite columns. This project aims to develop a new generation of concrete-filled steel tubular (CFST) columns free from reinforcement by using fly ash-based fire-resistant concrete. In Australia, existing CFST columns use a large amount of internal reinforcement to maintain the structural integrity under fire attack. Through the generation of CFST columns with superior fire resistance rating and associated design rules to enable innovative and safe applications of these columns in the construction of resilient and sustainable infrastructure, the project will enable expansion of the domestic and worldwide market for Australian producers of geo-polymer concrete and fly ash aggregates.Read moreRead less
Maximising the Use of Waste Glass in Sustainable Composite Columns. This project aims to develop novel structural concrete made with over 80% waste glass for use in manufacturing sustainable concrete-filled steel tubular columns used in buildings. Because of limited established markets for recycled glass, significant stockpiling of recycled and recyclable waste glass currently exists across Australia. This study will provide a suite of novel solutions to maximise the use of waste glass in struct ....Maximising the Use of Waste Glass in Sustainable Composite Columns. This project aims to develop novel structural concrete made with over 80% waste glass for use in manufacturing sustainable concrete-filled steel tubular columns used in buildings. Because of limited established markets for recycled glass, significant stockpiling of recycled and recyclable waste glass currently exists across Australia. This study will provide a suite of novel solutions to maximise the use of waste glass in structural concrete by fully replacing sand and gravel with crushed glass and up to 72% cement with glass powder. This will provide practical solutions to address not only Australia's glass recycling crisis but also the worldwide issue of disposal of waste glass.Read moreRead less

This project aims to quantify the development of the long-term (25-100 year) protective effect of calcareous deposits on the marine corrosion of mild steels. This is significant because such steels used extensively in major and very expensive coastal and offshore infrastructure. The project outcomes will improve scientific understanding, including the role of microbiological activity. It will develop and calibrate corrosion prediction models using classical and recently available 100 year data from Europe, the Pacific, Australia and also new project-specific experimental data. These models are expected to be of benefit for Australian engineering consultants in maintain their internationally competitive edge in offshore engineering.Read moreRead less
Concrete Mixes for Durability: A Hybrid Mathematical Optimisation Approach. This project will lead a paradigm shift in concrete mix design methodology, which is currently focused on meeting the mechanical performance objectives of concrete, to a holistic approach that maximises durability of concrete alongside its mechanical performance.

This project will lead a paradigm shift in concrete mix design methodology, which is currently focused on meeting the mechanical performance objectives of concrete, to a holistic approach that maximises durability of concrete alongside its mechanical performance. The approach is based on a hybrid methodology involving mathematical optimisation of concrete mix based on empirically formulated objective functions for durability properties and mechanical properties. The multi-objective nature of proposed optimisation model will allow simultaneous consideration of several design objectives including: minimising the overall risk of cracking, minimising the permeability; and maximising the rate of strength development.

The application of fibre reinforced polymer (FRP) composites in structural rehabilitation is sometimes challenged or opposed due to the limitation of its fire resistance. This project aims to solve the fire resistance problem of FRP in column jacketing work using innovative approaches. The proposed scheme will be developed by using advanced materials and mechanical fastening technology. It can ensure structural serviceability of FRP jackets during a fire. And after the fire, the proposed jacketing scheme is reusable by applying a new layer of epoxy. The project is expected to advance the theory and technologies in structural rehabilitation. It will also provide significant benefits to the construction industry via sustainable construction.Read moreRead less

The project aims to improve the guidance provided in Australian and New Zealand design codes for the seismic capacity assessment of heritage masonry buildings. The majority of culturally significant heritage buildings in Australia are constructed of unreinforced masonry, and all of these buildings were erected before seismic design guidelines or requirements existed. The risk posed by earthquakes to these important buildings is significant – as highlighted by the 2011 Christchurch earthquake where both major cathedrals in the city were heavily damaged. The project aims to develop an analysis and design method that accounts for the material properties and non-typical structural layouts used in heritage stone and clay brick masonry buildings that are most relevant to seismic response.Read moreRead less
