Abstract: Bridge fires have become relevant issue in recent years due to rapid development of navigational systems as well as increasing transport of hazardous materials. Fire is one of the most dreadful hazards that bridges may be subjected to during their whole lifespan. Due to high intensity of fires, significant structural damage, even collapse of bridges occur which lead to large economic loss and traffic delay. In this paper, the fire response of a composite bridge girder is evaluated using the FEM computer program ANSYS. Numerical simulation results demonstrate that the composite action from steel-girder–concrete-slab interaction significantly elevates the fire resistance of a composite bridge girder under fire conditions.
