One of high-rise structures' most popular and practical lateral load-resisting technologies is shear wall systems. They can handle massive horizontal and gravity loads concurrently because of their excellent plane stiffness and strength. Multi-storey structures increasingly need shear walls to endure lateral pressures like wind and seismic loads. It is crucial to ascertain the best placement for shear walls. Shear barriers must be positioned precisely since any variation will negatively impact your plan. The shear wall's shear contribution also highly depends on how far it is from the mass centre when the hardness and mass centre coincide. With a considerable reorganization of the shear wall placements, this study aims to identify the best possible structural layout for a multi-storey structure. A computer application program was used to build a frame system after four alternative shear wall placement scenarios for a multi-storey structure that maintains zero eccentricity between the mass and hardness centres. In compliance with IS specifications, the framed structure is tested for lateral and gravity loads. The best place for the shear wall is determined by analyzing the test results.
