This research paper studies the behaviour of different irregular plan buildings under seismic performance. The building plans, more severe damages which have eccentricity between center of mass and center of rigidity in compare to building plan which have no eccentricity between center of mass and center of rigidity. The buildings well during earthquake which have zero eccentricity. Most common shape of building plans as Square shape, ‘C’ shape, ‘L’ shape, ‘O’ shape, ‘+’ shape, and ‘Y’ shape which are repeatedly used in urban areas nowadays, which conforms as per clause 7.1 of IS Code 1893 (part 1)2016, are modelled by using ETABS software. Different parameters as Story drift, Story displacement, Torsion (Ratio of max story drift to average story drift), Total Base shear and Natural Time period are studied for six models. After analysis Response spectrum method, comparison of seismic performance of different models was performed and most vulnerable building shape against earthquake forces was located in this study for zone III.
