In last some years, it has been observed that, the high rise buildings are failed due to the various seismic and vertical failures in geometry. Hence we need more investigation on the structures with vertical irregularities under seismic. The effect of lateral load on structure with vertical irregularities should be examined to reduce failure of structure. This study summarizes the studies done on the seismic analysis of RCC building structure with different vertical irregularities. From the study, it has been concluded that the structure with vertical irregularity failed under seismic loading and need to find specific code or special design for such structures. The performance of a high rise building during a strong earthquake motions depends on the distribution of stiffness, strength and mass along both vertical and horizontal directions. If there is discontinuity in stiffness, strength and mass between the adjoining storeys of a building then such a building is called as irregular building. The present study focuses on vertical irregular G+11 reinforced structures (RC) building under seismic loading. Total four buildings are modeled and analyzed in software called as STRUCTURAL ANALYSIS AND DESIGN Pro (STAAD-PRO). Out of four buildings, one building is regular and 3 buildings are irregular. Different seismic responses like lateral story displacement, story shear force and story bending moment are obtained. By using these seismic response comparison has been made regular and irregular building. The results indicate a conclusion that, a building structures with stiffness irregularity provides instability during seismic loading. To overcome this instability or rather say that to control instability, an appropriate amount of stiffness is very vital in RC building.
