The catastrophic Minnesota River Bridge collapse in the USA in 2007 highlighted the importance of accurately assessing, maintaining, upgrading and prolonging the design life of our aging infrastructure. The problem, which is just as severe in Australia, is further exacerbated by increasing man-made (terrorist) hazards and natural hazards such as earthquake, tsunami, flood and bushfire. Reinforced concrete and composite steel-concrete structures comprise a very large part of Australia's bridge and building infrastructure. This project will provide a safe and more economical tool for engineers to both extend the working-life of existing infrastructure and design new infrastructure.
