چکیده مقاله:
Recently, the application of Composite Steel Plate Shear Walls (CSPSWs) and Steel Plate Shear Walls (SPSWs) as lateral load-resisting systems has been developed. These systems should be resistant enough, ductile, and stiffened to support against different types of excitations. In this work, the seismic performance of these two systems is investigated under different near- and far- field inputs. Strip elements are employed to model the CSPSW and SPSW in SAP2000. An experimental result of CSPSW is first verified. A six story building frame equipped with both systems is then modeled and six different far and near field seismic records are applied to the building frame. Nonlinear Time History Analyses (NTHAs) are conducted based on different maximum ground acceleration levels. Based on the results, appropriate seismic performance of CSPSWs can be clearly observed. More precisely, CSPSWs experience Life Safety (LS) performance level or at least Collapse Prevention (CP) performance level while SPSWs fully collapse
