STUDY OF SEISMIC BEHAVIOR OF MULTI-STORIED R.C.C. BUILDINGS WITH ETABS RESTING ON SLOPING GROUND

The buildings are present in sloping ground are very different from those in plain ground, in sloping ground the buildings are very irregular and unsymmetrical in horizontal and vertical planes. The buildings in sloping ground causes more damage during earthquake, because in sloping ground the structure is constructed with different column heights. In this study 3D analytical model of 8 storied building, In the present study a G+8 building with two different configurations i.e. Step back and step back set back with varying ground slope 0°, 15°, 25°, 30° are considered. To compare the behavior of regular configuration resting on plain ground a G+8 building having plan same as that of respective hill configuration are considered. Slabs are modeled as rigid diaphragms. Default hinge properties available in ETABS Nonlinear as per ATC- 40[6] are assigned to the frame elements. Building has no walls at all stories and is modeled as bare frame.
