In India, there have been several large earthquakes with magnitudes ranging from 4.0 to 8.6 that have destroyed buildings. As a result, various ways have been developed in the construction industry to withstand the effects of earthquakes on structures. Shear walls are one of the best ways to give earthquake protection multistory buildings, however it is crucial to find the shear wall’s most effective, efficient and optimum locations in the building. To adopt openings in the shear wall without significantly reducing the building's stiffness, a staggered shear wall is an innovative type of shear wall with effective performance. It also minimizes the weight and construction cost of the structure. The main goal of this thesis is to identify the best location of shear wall in irregular buildings with different irregular ratios by comparing structures with shear walls at various locations like, at the edges, at the corners and at both the corner and the edges. Further the dynamic analysis is carried out by considering optimum location of shear wall and replacing it with staggered shear wall. The effectiveness of staggered shear wall is studied by comparing the results with the shear wall structure having regular openings considering same percentage of openings in both the models using ETABS v18 software. From the study it is observed that staggered shear walls are more effective than the shear walls with regular openings. Staggered shear wall performs very well under seismic activity without affecting the stiffness of the building largely.
