Abstract: This research paper studies the behaviour of different irregular plan buildings during seismic excitation. The building plans, which have eccentricity between center of mass and center of rigidity are subjected to more severe damages in compare to building plan which have no eccentricity between center of mass and center of rigidity. The buildings which have zero eccentricity perform well during earthquake. Most common shape of building plans as Square shape, ‘L’ shape, ‘C’ shape, and ‘T’ shape, which are repeatedly used in urban areas nowadays, which conforms as per clause 7.1 of IS Code 1893 (part 1)2002, are modelled by using ETABS software. Different parameters as Story drift, Story displacement and Torsion (Ratio of max story drift to average story drift) are studied for four models. After analysis using Linear Time history method, comparison of seismic performance of different models was performed and most vulnerable building shape against earthquake forces was located in this study.
