Abstract

Abstract: Steel Plate Shear Walls (SPSW) can be used as an effective lateral load resisting system for highly seismic zones. The Present aim of study is to identify the optimum perforations pattern in SPSW. The behaviour of the Steel Plate Shear Walls with different shapes and locations of perforations is studied in the present work and compared with three configurations, i.e., diagonal, partially stripped, fully stripped openings. A 30 m × 30 m plan of a building with SPSW with perforations at specified locations for 5 storey, 10storey, 15storey and 20 stories is considered. Time period, lateral stiffness, lateral displacements and maximum story drift due to different earthquake time histories and wind loads is performed using non-linear time history analysis. The responses are compared and the optimum opening configuration is found to be middle strip SPSW system shows with better performance against seismic loads and full strip SPSW systems shows better performance against wind loads.
