This paper presents an evaluation of the performance of industrial steel structures under fire load. This evaluation was performed on the structure of Mashhad metro line 2 stabling building which is one of the largest sheds in the depot site of line 2 of Mashhad metro. For this purpose, numerical analysis using finite element method has been used. The main components of fire resistance include columns and rafters so elements with low fire resistance, such as purlin, have been removed to investigation the structural fire resistance. The results of the analysis showed that the structure of the stabling building, under the most critical fire scenario, has a minimum fire resistance of 110 minutes against the collapse caused by fire. Also, by examining two different fire scenarios, it was identified that uniform fire scenario creates a more critical situation than the non-uniform fire scenario. It is suggested that for the design of other similar structures, effective fire protection be provided for the rafters and panel zones to guarantee the stability of the structure.
