This project aims to develop innovative metaconcrete for structural protection by utilising the concept of phononic crystals and metamaterials which has been recently developed by physicists. Traditional construction materials are used in new structural forms to mitigate dynamic loading effects by exploiting the unique characteristics of the proposed metaconcrete. Theoretical, numerical and experimental methods will be used to derive the best performing metaconcrete and verify its static and dynamic load resistant capacities. The expected outcomes of the project will lead to innovative extreme-loading resistant designs and provide significant benefit to the Australian construction industry, general public and economy.Read moreRead less
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
Measuring and modelling the mechanical response of soils incorporating recycled tyres. Civil engineers use backfill to refill excavated areas around new structures. They have found recently that rubber chips and shredded rubber make excellent backfill when combined with a small percentage of cement to make ‘rubber soil’. The widespread use of rubber soil therefore offers a tremendous opportunity to make use of a serious waste product to achieve important engineering outcomes. However, too little ....Measuring and modelling the mechanical response of soils incorporating recycled tyres. Civil engineers use backfill to refill excavated areas around new structures. They have found recently that rubber chips and shredded rubber make excellent backfill when combined with a small percentage of cement to make ‘rubber soil’. The widespread use of rubber soil therefore offers a tremendous opportunity to make use of a serious waste product to achieve important engineering outcomes. However, too little is known about the technology. This project will model the behaviour of rubber soil in order to introduce it as an environmentally sustainable, cost-effective and technically sound choice of geomaterial for both standard and non-standard geotechnical structures.Read moreRead less

This project aims to provide structural engineers with the tools required to develop ultra-high performance fibre reinforced concrete materials and to utilise their unique material properties in design. Recent feasibility studies have shown that the replacement of conventional concrete and steel transport infrastructure with ultra-high performance fibre reinforced concrete has the potential to revolutionise the sector. For these cost savings benefits to be realised, guidelines for the low cost development and testing of new materials, and for the application in structural design are required. This project is expected to deliver these guidelines and potentially maximise the impact of government spending on road and rail infrastructure.Read moreRead less
Earthquake protection of masonry buildings using fibre reinforced polymer strengthening. The importance of this research is highlighted, both nationally and internationally, by the work of the insurance industry which reported that the economic risk posed by a moderate earthquake in any of the capital cities in Australia is of the order of billions of dollars (Blong, 1993). For example, a 'design magnitude' earthquake in Sydney is predicted to cause, just in domestic construction, over $10 bill ....Earthquake protection of masonry buildings using fibre reinforced polymer strengthening. The importance of this research is highlighted, both nationally and internationally, by the work of the insurance industry which reported that the economic risk posed by a moderate earthquake in any of the capital cities in Australia is of the order of billions of dollars (Blong, 1993). For example, a 'design magnitude' earthquake in Sydney is predicted to cause, just in domestic construction, over $10 billion damage and more than 5000 deaths. Most of this damage would be associated with unreinforced masonry construction such as low-rise apartment buildings. The damage bill for the entire built environment (with business interruption costs) could easily be an order of magnitude greater.Read moreRead less
