摘要：Mostly hilly regions of India are highly seismic. Sloped Buildings are differs in different way from other buildings. Buildings builted in hilly areas are much more vulnerable to seismic environment. The various floors of sloped building steps back towards the hill slope and at the same time buildings may have setbacks also. Analysis of such buildings is somewhat different than the buildings on leveled ground, since the column of such building rests at different levels on the slope. In present study, the analysis of G+3 and G+4 buildings on varying slope angles i.e. 00 , 7.500 , 15.00 , 22.500 and 30.00 has been conducted. Both type of building configurations i.e, step back and step back setback has been considered. The seismic forces are considered as per IS: 1893‐2002. The buildings are considered in seismic zone IV and damping ratio 5%. Seismic analysis has been done using Linear Static, Linear Dynamic method. The 3D analytical models of buildings have been generated and analyzed using structural analysis tool “STAAD. Pro 2007” to study the effect of varying height of columns in ground storey due to sloping ground. The response parameters such as base shear, top storey displacement, shear in bottom storey column, time period are critically analyzed to quantify the effects of various sloping ground. It is found that column on the higher side of slope i.e. short columns are subjected to large shear force than longer columns on lower side. The step back setback buildings performed better than step back buildings under earthquake forces. The base shear and top storey displacement in step back setback buildings is much lower than the setback buildings on the sloping ground.
