Resumen
Composite Steel Plate Shear Wall (CSPSW) is a resistant system to lateral forces with suitable performance which can be utilized by corrugated trapezoidal plates enhancing the stiffness of shear wall. In this study, when the space between the corrugations of trapezoidal plates is either filled or empty, the deformability, stiffness and other seismic parameters of Composite Steel Plate Shear Wall have been studied by Abaqus software. The use of CSPSW with corrugated trapezoidal plate with horizontal and vertical corrugations when the space between the corrugations of Infill plate and concrete layer is empty exhibits more deformability as compared to just the same system when the space has been filled with concrete layer. In fact, applying this application detail in CSPSW with corrugated trapezoidal plate is believed to improve the behavior of this lateral resistant system. If we use trapezoidal plate in CSPSW, it would be recommended that the space between corrugations and concrete layer to be empty.
