Abstract: The Buildings on the hills differs from other buildings constructed in plain terrain. Each floor of building steps back towards the hill slope and at the same time buildings may have designed with setbacks configuration also. Buildings constructed in hilly areas are more vulnerable to seismic environment. This study is on generating a 3D analytical model of multi-storey buildings analyzed using structural analysis tool ‘ETABS” to study the effect of varying height of columns due to sloping ground and the effect of bracing at different positions in a different configuration of the building during an earthquake. Seismic analysis has been done using the response spectrum method. The performance of the buildings on the sloping ground is highly vulnerable to earthquake on each storey level. Buildings resting on sloping ground with step back configuration are compared to buildings resting on the plain ground with same type load applied to each of the structure. From this study entire modelling the behaviour of normal ten storey building, step back, set-step back ten storey building is studied, it is found that the displacement and base shear value shows the performance of step back building and set-step back building. This is research also focus on effective placement of bracing with different types and in different positions. The displacement values show better performance by providing X bracing in the lateral direction.
