Comparative Analysis of RC Framed Structures under the Effect of Sloping Ground with Setback Configurations under Seismic Conditions

Since the population of world increases drastically from last few decades, due to this there is scarcity of land. In such conditions, most of the population have been located in hilly areas. Utmost of hilly regions in northern India where seismic actions are common, buildings are mandatory to be erected on sloping ground due to insufficiency of plain land. And in hilly regions, due to sloping land most of the structures has been constructed with step back and set back configurations. Such building having these configurations in hilly areas are much more susceptible to seismic environment. These building are generally irregular or torsion ally coupled and hence liable to severe damage when affected by earthquake ground motion. The main purpose of this study is to perceive the behaviour of such buildings with different configurations like step back and setback under sloping or levelled ground which helps structural engineer to understand its sustainability, its behaviour, its response against lateral and is to review further technologies for seismic damage which help to prevent or control the seismic damage. In this study, analysis of building located in hilly areas with varying sloping ground conditions with step back and setback configurations compared with the building on levelled ground, by using response spectrum method as per IS1893-2016 using ETabs has been carried out. This study helps to identify the response & behaviour for sloping and levelled ground, step back-setback building in severe earthquakes.
