Abstract: To avoid the damages from horizontal forces such as seismic forces and wind forces, the provision of a lateral force resisting system in the structure is essential. Lateral forces develop high stresses, produce sway movement or cause vibration, which leads to structural failure and therefore, it is crucial for the structure to have sufficient strength against vertical loads together with adequate stiffness to resist lateral loads. Shear walls offer effective means of providing in-plane lateral force resistance, typically to the wind and seismic loads in multi-story buildings. Shear wall systems have high plane stiffness and strength which can be utilized to resist large horizontal loads and support gravity loads simultaneously, making them advantageous in many structural engineering applications. Since the incorporation of shear walls in multi-storey buildings has now become a requirement, it is necessary to determine the most effective and accurate location of shear walls. When the mass center and hardness center coincide with each other, the distance of the shear wall from the mass center plays a significant role in the shear contribution of the shear wall. This paper presents the response of a building with different positioning of the shear wall using Response Spectrum Analysis and Wind load Analysis. Five different models of RCC buildings, one with no shear wall and the other four models with different positioning of the shear wall, subjected to earthquake load and wind load has been studied. The performance of each storey of a 20-storey building is evaluated for different combinations of loads applied. The analysis is done by structural finite element analysis method using SAP2000 software.
