This paper investigated the thermomechanical performance of a simply-supported steel girder bridge above a tanker fire by coupling the computational fluid dynamics (CFD) method and finite element method (FEM). Numerical results show that the presented method was able to replicate the inhomogeneous thermomechanical response of box bridges exposed to real fires. The girder failed due to the buckling of a central diaphragm after the ignition of the investigated tanker fire in no more than 10 min. The framework presented in this study is programmatic and friendly to researchers and can be applied to estimate bridges in different fire conditions. |
