Abstract

The seismic responses of structures on sloping areas are fairly different as compared to the flat ground. Step back and set back structures have geometrical irregularity; hence, these structures are more vulnerable to earthquakes on the inclined ground. In this paper, an attempt has been made to evaluate the seismic performance of reinforced concrete buildings on flat and sloping ground with sloping angles such as 20°, 30° and 40°. The response spectrum method of analysis has been performed using by ETABS v 17.0.1. The earthquake resistance codes IS 1893 (Part 1): 2016 and IS 13920: 2016 have been referred in this study. Results are discussed in terms of base shear, storey drift, storey stiffness, short column effect and overturning moment for the plain and inclined ground with different inclinations. In inclined ground structures under seismic loads, the short column effect is a common problem; hence, the discussion of critical issues of step back and set back structures is presented for different slope angles.
