摘要：Bridge fire response is a barely studied topic not covered in current design codes despite the frequency and consequences of this kind of events.Within this context, this paper analyzes the response of a multi-girder steel bridge in real fires caused by a tanker.To reach this goal, fire models of the bridge and its surroundings are done using Computer Fluid Dynamics (CFD) techniques, and then an uncoupled thermo-mechanical analysis of the most fire affected bridge girders is carried out.The study analyzes modeling features as well as the influence of the position of the tanker and the existence of gas spills.Results are interesting for both researchers and engineers and show (a) the importance of considering real fires and not simplified models, and (b) the need to develop a performance based approach specific to bridge fire design.
