INFLUENCE OF GROUND SLOPE ON THE SEISMIC RESPONSE OF REGULAR AND IRREGULAR BUILDINGS

Abstract

In a growing nation such as India, land scarcity resulting from urbanisation and industrialisation has facilitated the development of high-rise multi-storey structures in hilly areas. Structures erected on inclines vary from those built on level terrain due to their uneven and asymmetrical configurations in both vertical and horizontal planes. Furthermore, structures situated on elevated terrain are far more susceptible to seismic shocks. The primary aim of this research is to examine the performance of structures on inclined and level terrain. Structures situated on elevated terrain must be designed differently from those on level land. Hill structures vary from those on plains; they exhibit significant irregularity and asymmetry in both horizontal and vertical planes, and are torsionally linked, rendering them vulnerable to severe damage during seismic events. This research examines the behaviour of regular and irregular multi-story buildings with two distinct slope angles, comparing them to level ground conditions. by examining seismic zone V. A comparison is conducted between flat ground construction and sloping ground construction. The models are developed via ETABS structural analysis software. The analysis is conducted with response spectrum analysis. The analytical findings, including displacement, moments, storey shear, and storey drifts, are tallied and examined.
