STUDY OF SHEAR WALLS IN MULTISTORIED BUILDINGS WITH DIFFERENT THICKNESS AND REINFORCEMENT PERCENTAGE FOR ALL SEISMIC ZONES IN INDIA

Abstract

This paper investigates the effect of different thickness and corresponding reinforcement percentages required for shear walls on multi-storied buildings. Building models with shear walls are developed using ETABS. The location of the shear walls are kept same and a comparative study is done for different thickness of the shear wall for different height of the building (5 storied, 10 storied and 15 storied). In each of the cases corresponding reinforcement percentages required are found out. It is observed that for a constant thickness of shear wall, reinforcement percentage increases with increase of both seismicity and number of stories. It is also observed that for all zones, the reinforcement percentage increases if the shear wall thickness increases for a certain range of thickness and then decreases for a certain range of thickness. Thus the results indicate that increase of shear wall thickness is not always effective for earthquake resistant design.
