Due to the asymmetry or irregularity in building plan, there may be chance of amplification of torsional effects in during varying earthquake ground motions. Thus, irregularity in plan i.e. stiffness of vertical members will cause torsional eccentricity i.e. centre of mass and centre of rigidity shift away from each other. This eccentricity will cause torsional moments under seismic forces and this may vary from floor to floor. In this study three models which are G+5, G+10, G+15 were considered for two different conditions. In first case the variation of torsional moments in columns with respect to height of building and variation of base shear in all seismic zones were studied. Critical positions of columns were identified. The reason behind the results given to columns is columns are more vulnerable to seismic loading. In second case the variation of storey torsional moments and additional shear developed by torsion were studied. The results were recorded to in both X,Y directions due to asymmetry of building models. The Indian standard code of practice IS1893:2002 (Part I) guidelines and methodology were used to analyzed and designed building.
