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
