Abstract: Earthquake is a major concern in high seismic prone areas. The structure which lies in seismic zones are to be specially designed. The goal of earthquake-resistant design is to construct structures that fare better during seismic activity than their conventional counterparts. In this paper a study is conducted on the performance of a asymmetric structure, with plan irregularity, strength and stiffness irregularities. The factors which influence the earthquake resistance in a structure are Shear wall, Strong column, Base isolation, Brick infill and use of dampers. Out of above parameters, some of the above parameters are considered for the current study, like Shear wall, Strong column, Brick infill. A time history analysis is performed using SAP 2000 software, a comparative discussion is made on the response of structure between normal building and building which is designed for earthquake resistant. The results showed that it was important to select a suitable parameter, for the type of resistance that the building must offer. This parametric study clears the importance of each earthquake resistance factors.
