Abstract	An earthquake is known as a devastating and feared calamity on Earth due to the sudden release of energy from beneath the surface, causing movement in the crust. This movement subject structures in contact with the ground to seismic forces. To resist the lateral forces produced by earthquake and wind we are providing shear walls and friction dampers.This paper aims to study the behavior of high-rise irregular structures with shear walls and frictional dampers when subjected to horizontal forces caused by earthquake. In this study, a series of G+40 buildings are compared with similar structures after adding shear walls and frictional dampers for various seismic zones using the response spectrum method. All structures will be compared to regular structures under the same conditions. Dynamic analysis is carried out on different soil types in various seismic zones. The response spectrum method is a seismic analysis technique that provides the response of structures subjected to seismic loads. The complete modeling and analysis are performed using the well-known FEM integrated software "ETABS," considering relevant data for specific seismic zones according to IS 1893(Part 1): 2016. All reinforcement criteria for RCC structure components will be considered according to IS 456:2000 and IS 13920:2016. By the results we can conclude that the structure with shear walls is more susceptible compared to the other two structures. Mostly shear walls should be provided in zone V. In zone IV and V the structure with shear walls, displacement is reduced by 34% & 30% and base shear is increased by 61% and 40%.
