In this research a 3-storey metro station are selected. For assess the progressive collapse of these structures, the damaged walls should be modeled in software. The progressive collapse was assessed by nonlinear dynamic and static analysis. The alternative load path is the most important factor to the resistance, so the failure of the wall because of the high degree of freedom and existence of many shear walls, this structure wasn’t prone to progressive collapse. The explosion damages the metro, with the destruction of 30% of wall the tension ratio increase 3.9% and with the destruction of 60% of wall the tension ratio increase to 12.3% and with the total wall damage, the tension ratio increase to 16.4% .
