Review on Influence of Provision of Shear Wall in Multistory RC Frame Building

Abstract

Shear walls are used in tall buildings as supporting elements to resist earthquake loading. In order to enhance the ductility of the structural system the walls are connected together with lateral beams. Many researchers have investigated the behaviour of shear walls using different methods. Analytical methods are one of the early techniques used in the analysis of shear walls. During an earthquake, damage to buildings is largely caused by dynamic loads. Therefore, in order to design buildings resistant to earthquakes, the dynamic characteristics of the building must be known. Generally tall buildings may consist of any combination of structural forms, such as frames, shear walls, structural cores, and coupled shear walls. Lateral forces caused by wind, earthquake, and uneven settlement loads, in addition to the weight of structure and people living; create torsion in structure. Shear wall system is one of the most commonly used lateral load resisting system in high rise buildings. Shear wall has high in plane stiffness and strength which can be used to simultaneously resist large horizontal loads and support gravity loads, which significantly reduces lateral sway of the building and thereby reduces damage to structure and its contents.
