Abstract:
Steel plate shear walls (SPSWs) are popular lateral force resisting systems whose practical applications range from high seismic regions to medium and low seismic areas and wind load applications. The factors which make SPSW attractive include its energy dissipation capacity, excellent ductility, constructability, speed of construction compared to concrete shear walls, reduced architectural footprint compared to concrete shear walls, and increased inelastic deformation capacity as compared to braced frames and concrete shear walls.
In this research, characteristics and behavior of un-stiffened perforated SPSWs using non-linear finite elements software has been investigated. In order to that, 24 SPSW in two category consist of SPSWs with central perforation and SPSWs with perforation near to upper edge of the infill plate, in three story height: three, seven, ten and twelve-story has been modeled. It has been shown that using perforations near the upper edge of the infill plate has 20 percent more energy absorption, and 12 percent less displacement then SPSWs with central placed perforations
