Abstract

The complex nonlinear properties of concrete make it difficult to determine its true strength and response under loading conditions. This has often lead to many reinforced concrete structures such as bridge decks being over designed. Finite element analysis techniques such as the smeared crack approach have now been developed to model concrete structures with considerable accuracy. This dissertation uses the general purpose finite element software ABAQUS to model a composite bridge deck that comprises of a reinforced concrete slab and longitudinal steel girders. Three separate models were produced with different girder spacings. Loading conditions were determined from the Australian Standard for Bridge Design and used on the structure to produce the worst effects. From this the response of the bridge deck was determined and an optimum girder spacing chosen. It was found that a four girder bridge deck would provide the optimum design for a two lane bridge to meet Australian Standards.
