Result from seismic analyses performed on 4 RC buildings with two different configurations in horizontal and vertical. In vertical like; step back building and step back-set back building and in horizontal symmetrical and unsymmetrical in the terms of bays are presented. Analysis including torsional effect has been carried out by using response spectrum method. The dynamic response properties i.e. fundamental time period, top story displacement and the base shear induced in columns have been studied with reference to the suitability of a building configuration on sloping ground. It is observed that step back-set back buildings are more suitable on sloping ground as compared to step back building.
