The hilly region of North India is developing at a rapid pace, resulting in the construction of high-rise buildings on sloping ground. Forces generated by earthquakes are enormous and dynamic. Since these buildings are asymmetrical, a huge amount of shear forces and torsional moments are attracted by them due to their irregular column height experiencing seismic loads. Dynamic characteristics of these irregular buildings are different from the buildings located on plane topography. As the foundation of these buildings is located on different levels of the ground, short columns experience high stiffness and brittle failure. Eight standard moment-resisting frames (SMRF) setback buildings have been designed by following the Indian standard code and the Federal Emergency Management Agency (FEMA). A direct displacement-based design (DDBD) approach has been performed. However, four buildings have been taken as frame buildings without infill walls, and the remaining four were taken as frame buildings with infill walls. Variation in inter-storey drift, base shear, displacement and stiffness have been compared, as obtained from the DDBD approach. The present study also elucidates the implication of performance-based assessment techniques to identify the effect on seismic collapse resistance due to specific design requirements.
