Abstract

Tall buildings which are vertically cantilevered structures from the ground level are subjected to earthquake and wind forces and also axial loading. The shear wall is used in high rise structures to resists these lateral forces. In this study, analytical investigation is done to examine the performance of flanged, L-shaped and box-type shear walls with and without openings in high rise buildings under seismic excitation for regular and irregular reinforced concrete buildings. The models were designed on ETABS v.15 software and are analyzed by response spectrum method as per IS 1893 (Part 1): 2002 for various parameters like displacement, story drift, base shear and member forces. Two types of structures, regular and irregular plan shaped are analyzed with three types of shear wall with and without openings. Result shows that the presence of openings in shear wall affects the strength and rigidity of the shear wall depending upon the size of openings. The floor area increased of some parts due to the column reduction and shear wall application in the buildings.
