Study on Seismic Performance of Buildings Resting on Sloping Grounds with and without Shear Wall

The buildings in hilly areas have to be configured differently due to scarcity of flat ground. In hilly areas buildings are built on sloping grounds. When the hilly areas come under the seismic zones, these buildings are highly vulnerable to earthquakes. The stability of the structure is at risk due to the un-symmetric frame of the building due to different levels of column foundations. This paper deals with the comparison of G+9 residential buildings for seismic performance resting on sloping grounds without and with shear walls retrofitted when subjected on earthquake forces in zone III and in two different types of soils (soft and hard soils). The structures are analyzed by non-linear dynamic analysis (Response Spectrum Analysis-as per IS 1893–2002) using “ETABS 13.0” for a constant sloping ground of 30° with horizontal. With this we can study the performance evaluation of building under the presence of shear wall, storey shear, displacements and storey drifts at each storey were determined and compared. The main aim is to check if the seismic performance of the structure is improved when it is retrofitted with shear wall.
