Abstract: In the present study, the term 'Hill Buildings' refers to buildings located on hill slopes with foundations placed at different elevations. The structural configurations of these buildings are quite different as compared to regular buildings located on flat terrain. Hill buildings are characterized by stiffness and strength irregularities which are mainly due to the presence of short stiff columns on the building's uphill side. In order to identify typical structural configurations of hill buildings in the Indian Himalayas, field studies were conducted in the northern Indian cities of Mussoorie and Nainital. The step-back configuration, which is the most prevalent building configuration in Indian hill regions, has been chosen for detailed investigation. A generic building with step-back configuration is designed for different design levels as per relevant Indian codes. The seismic performance of the various building models has been studied using bi-directional incremental dynamic analysis (IDA). It is observed that the primary failure mode is governed by shear failure of short columns, while it can be generally said that hill buildings possess much lower seismic capacity than their counterparts located on flat ground.
