Increase in the population leads to shortage of the plain land for the construction. A frame building on hill slopes is the only possible choice to accommodate increasing demand of residential and commercial building. Usually Seismic activities are higher in hilly areas of north India. Building has to construct on sloped region due to shortage of flat land. Hence earthquake activity requires great observation in analysis& design due to its destruction power. Analysis of buildings in hill region is somewhat different than the buildings on levelled ground. Due to site conditions, buildings on hill-slopes have an unequal column height which results in shorter column attracts more forces and undergoes damage, subjected to earthquakes. In the present study, the response spectrum method is carried out on two basic type of structure that rests on sloping ground. Building frame with stepback and stepback-setback are considered and are analysed with varying parameters such as slope and height. All the Eighteen models were analysed using ETABS v17 and results were discussed in terms of storey displacement, storey shear, time period and storey drift and best configuration is suggested based on the results and that can be adopted.
