Abstract

In countries like India where the mountains, hills and the plateaus form a significant part of its terrain. It is the increasing demand of the time to construct the RCC Buildings in hilly regions due to urbanization. The construction at hills is different from plains as they are more prone to seismic activities. As the buildings on sloping areas are having irregularities, the behavior of the building during earthquake depends upon the distribution of the mass and stiffness in both the horizontal and vertical direction. They are more susceptible to severe damage. Moreover, during earthquake, irregular buildings in hilly areas serve more damage. Dynamic response of hill buildings is somewhat different than the buildings on flat ground. Short column of RC frame building serves damage because of attracting more forces during earthquake. The RCC Buildings on the hilly regions are narrowed down to basic formats as step back and set back - step back and set back frames. The dynamic response i.e. fundamental time period, storey displacement and drift, and base shear action induced in buildings have been studied for buildings of different heights. The regular, set back and step back building frames are analyzed and compared in this study.
