Analysis of the influence of geometric, modeling and environmental parameters on the fire response of steel bridges subjected to realistic fire scenarios
The response of a bridge to realistic fire scenarios is obtained using CFD and FE models. Influence of fire position, vertical clearance, deck substructure and wind is studied. Analysis of the most exposed girder provides conservative results. Numerical modeling guidelines are provided. Research is valuable for a performance-based approach to bridge fire design.
