Scope

To our knowledge, till now, the seismic performance of perforated steel plate shear walls under fire condition has not been evaluated and compared at different temperatures. In this paper, the perforated steel plate shear wall with infill plates with a thickness of 2.67, 5 and 7 mm and also with yield stresses of 165, 256 and 300 is modelled and their seismic performance in terms of stiffness, ultimate strength and ductility, before and after applying the load is compared under fire condition fire at temperatures of 458, 642 and 917 °C.
