Due to growth of population and narrowness of available land, people have to choose hill side slopes to build their houses. The behaviour of buildings during earthquake depends upon the distribution of stiffness and mass in both horizontal and vertical planes of the buildings. In hilly regions these buildings are irregular and unsymmetrical in both horizontal and vertical planes. Such constructions in seismically prone areas make them exposed to greater shear and torsion.This paper presents the effect of different slope angle on the performance of step back R.C.C. building under the seismic and gravity loading, using Response Spectrum analysis method and E-TABS 2017 software.The performance of the buildings is analysed on the basis of seismic parameter viz, time period, base shear, storey displacement, storey drift, storey stiffness, torsional irregularity and shear force as per IS 1893-2016: Part-I guidelines. It was observed as the angle of slope increases column on uphill side of buildings attract higher shear force, there is variation of stiffness along height of building that show soft storey effects in bottom storey and building undergoes significant torsion.
