Abstract: Structural design and analysis produces the capability of resisting all the applied loads without failure during its intended life. Lateral loads mainly due to earthquake govern the design of high-rise buildings. The interior structural system or exterior structural system provides the resistance to lateral loads in the structure. The present paper describes the analysis and design of high-rise buildings with Steel Plate Shear Wall (SPSW) for (G+20) stories. The properties of Steel

... te shear wall system include the stiffness for control of structural displacement, ductile failure mechanism and high-energy absorption. The design and analysis of the composite building with steel plate shear wall is carried out using software ETABS. The present study is to carry out the response spectrum analysis of a high-rise composite building by optimizing the thickness of steel plate shear wall and to compare the results of displacement, story drift, overturning moment and story shear. The models are analyzed by Response Spectrum analysis as per IS 1893:2002. All structural members are designed as per IS 456:2002 & IS 800:2007 considering all load combinations.
