Earthquakes are the most devastating natural hazards in terms of life and property loss of any region. About 60% of the land area of our country is likely to damaging levels of seismic hazard. The response of the structure during earthquake greatly depends on the size, geometry and shape of the structure. The earthquake investigators repeatedly confirm that the irregular structure suffer more damage than the regular structure. The present study is to evaluate the seismic performance of G+9 RCC building frame with and without vertical irregularities subjected to earthquake forces in zone III. The structures are modelled and analyzed using SAP 2000 software. Comparison of seismic response of the structure in terms of base shear and displacement along with the location of the plastic hinges at the performance point of all the models are considered. Based on the above response parameters, the results and conclusions are drawn.
