This project intends to explore the possibilities of extending the latest developments in auxetic technologies to the protective design of engineering structures. Auxetic materials become thicker perpendicular to the applied force when stretched. Specifically, the project plans to develop a novel auxetic composite system with a focus on protecting civil and defence infrastructure from extreme loads. It is expected that the system’s superior energy dissipating capability will broaden its application beyond civil infrastructure, such as armoured vehicles, protective sports gear and body armour. The project also plans to develop a multiscale numerical modelling and topological optimisation framework to accelerate the adoption of this advanced composite system.Read moreRead less

A study of the correlation between pre- and post- demolition performance assessment for prestressed concrete beams in a 45 year old major road bridge. In 2002 a major prestressed concrete bridge in Tasmania was demolished after only 45 years in service because of fears about the corrosion of the prestressing bars. Earlier, very extensive investigations were carried out to attempt to assess the rate of its deterioration and to establish the remaining margin of safety.
The present project aims ....A study of the correlation between pre- and post- demolition performance assessment for prestressed concrete beams in a 45 year old major road bridge. In 2002 a major prestressed concrete bridge in Tasmania was demolished after only 45 years in service because of fears about the corrosion of the prestressing bars. Earlier, very extensive investigations were carried out to attempt to assess the rate of its deterioration and to establish the remaining margin of safety.
The present project aims to investigate the degree of correlation between the performance assessment before and after demolition. Extensive pre-demolition documentation provided by the industry partner and detailed new assessments will give valuable research insight about the meaningfulness and reliability of investigative techniques for safety assessment. It will assist road authorities in structural assessment of bridges close to coastal marine environments.

Stochastic Modelling of Strength and Reliability of Masonry Walls Loaded in Flexure and Compression. For new construction, a more efficient use of structural masonry will mean that less material will be used when compared to masonry structures designed to existing design specifications. This will result in lower construction costs, reduced energy costs and could help contribute to an increase in building approvals. The ability to more accurately assess the safety of existing masonry structures m ....Stochastic Modelling of Strength and Reliability of Masonry Walls Loaded in Flexure and Compression. For new construction, a more efficient use of structural masonry will mean that less material will be used when compared to masonry structures designed to existing design specifications. This will result in lower construction costs, reduced energy costs and could help contribute to an increase in building approvals. The ability to more accurately assess the safety of existing masonry structures may allow authorities to avoid unnecessary demolition or rehabilitation of such structures. Such infrastructure includes much of Australia's domestic housing, light commercial structures, numerous heritage buildings, and many structures required to serve a post disaster function.Read moreRead less

Assessment of structural integrity and deterioration of masonry walls. Brickwork for housing and medium-rise buildings is a traditional material, also much used for modern construction, with aesthetic appeal and modest cost. However, building regulators and others are increasingly concerned about evidence of slow building deterioration, particularly of older buildings. This increases public safety risks, even under normal conditions and more so under high winds or earthquake-induced ground-shaki ....Assessment of structural integrity and deterioration of masonry walls. Brickwork for housing and medium-rise buildings is a traditional material, also much used for modern construction, with aesthetic appeal and modest cost. However, building regulators and others are increasingly concerned about evidence of slow building deterioration, particularly of older buildings. This increases public safety risks, even under normal conditions and more so under high winds or earthquake-induced ground-shaking. This project will help address this issue. It will obtain unbiased evidence of typical masonry building deterioration. It will couple this with mathematical modelling and state-of-the-art non-destructive visual and dynamic techniques to develop tools for making fast, low-cost practical building risk assessments.Read moreRead less
