Effects of Sloping Ground on Step-Back Configurations of RCC Building under Sismic Load

Present study summarizes the behavior of buildings on hill slopes. The analysis of G+3 buildings on varying slope angles i.e. 00, 7.50, 300, and 600 has been conducted. Step back building configurations 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%. 3D analytical model of buildings have been generated and analyzed using structural analysis tool “STAAD. Pro V8i� to study the effect of varying height of columns in ground storey due to sloping ground. The response parameters 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.
