ADDITION OF SHEAR WALLS TO ENHANCE THE STRUCTURAL STABILITY OF MEDIUM RISE STRUCTURES

Abstract

Shear wall systems are one of the most commonly used lateral load resisting in high rise building. Shear wall has high plane stiffness and strength which can be used to simultaneously resist large horizontal loads and support gravity loads. Incorporation of shear walls has become inevitable in multi-storey buildings to resist lateral forces. Hence it is very necessary to determine effective, efficient and ideal location of shear wall. Shear wall arrangement must be absolutely accurate, if not, we will find negative effect instead.  In this project, a study will be carried out to determine the optimum structural configuration of a multistory building by changing the shear wall locations radically. Four different cases of shear wall position for G+9 storey building with keeping zero eccentricity between mass center and hardness center will be analyzed and designed as a frame system by computer application software ETABS. The framed structure will be  subjected to lateral and gravity loading in accordance with IS provision and the results will then be analyzed to determine the optimum positioning of the Shear wall.
