Abstract
Most of the hilly regions in India are highly seismic. A building resting on hilly slope region differs in quite different way from the buildings located at plane surfaces. The buildings are situated in hilly areas are much more vulnerable to seismic environment. The various floor levels of such building steps back towards the hill slope and at the same time buildings may have setbacks also. Analysis of hilly slope buildings is somewhat different than the ground level buildings, since the column of such building rests at different levels on the slope. In present study, the analysis of G+3 buildings on varying slope angles includes respectively. The seismic forces are considered as per IS: 1893-2002. The buildings are considered to be located at seismic zone III with the damping ratio of 5%. Seismic analysis has been performed using Equivalent static analysis. The 3D analytical model of buildings has been generated and analyzed using STAAD.Pro to study the effect of varying height of columns in ground storey due to sloping ground.
