EVALUATING DIFFERENT SHEAR WALL PLACEMENTS IN MULTI STOREYED STRUCTURES

Vivek Sungaria, Mitali Shrivastava

Abstract

Shear walls are one of the most commonly used lateral load resisting systems in high rises. They have high plane stiffness and strength which can be used to simultaneously resist large horizontal loads and also to support gravity loads. Incorporation of shear walls has now become inevitable in multi-storey structures. Hence it is very necessary to determine effective, efficient and ideal location of shear wall. Shear wall arrangement must be absolutely accurate, if not, it may cause negative effect instead. In this project, a study has been carried out to determine the effect of addition of shear walls and also the optimum structural configuration of a multistory building by changing the shear wall locations radically. Four different cases of shear wall position for G+10 storey building with keeping zero eccentricity between mass center and hardness center have been analyzed and designed as a frame system by computer application software ETABS. The framed structure is subjected to lateral and gravity loading in accordance with IS provision and the results are analyzed to determine the optimum positioning of the Shear wall.
