Irregularities in buildings are a cause for concern when they are subjected to destructive earthquakes. Buildings often become unstable when their vertical or plan configuration suddenly changes. To prevent failure and reduce the risk potential of irregular structures, proper precautions should be taken to resist lateral loads. One of the most practical and commonly used mechanisms to protect against lateral loads for high-rise buildings in earthquake-prone areas is shear wall systems. It is critical to properly assess the earthquake response of the walls because the properties of these seismic shear walls greatly affect the response of the building. Buildings with shear walls reduce the lateral deflection of the structure, but the effectiveness of the shear wall in terms of lateral strength of the structure depends strongly on the position of the shear wall. The main objective of the current work is to find the appropriate position of shear wall in irregular multistory buildings. Four different models of irregular buildings were used to study the effectiveness of shear walls. The first model is a bare frame, and the other models are irregular frames with shear walls at different locations. A response spectral analysis is performed in the STAAD Pro software. Based on the results, the optimal model for strategic positioning of the shear wall and minimizing the overall response of the structure is determined by comparing the results of parameters such as projectile drift, axial force, and base shear.
