Comparative Study of Seismic Analysis of Reinforced Concrete Framed Buildings on Hill Slopes

Abstract: In the northern and northeastern regions of India, hilly terrain is widespread, making buildings in these areas more susceptible to seismic activity compared to those in flat regions. The structural integrity of buildings on sloping ground differs significantly due to their irregular and asymmetrical nature, increasing vulnerability to torsional moments during earthquakes. Variations in column height on sloping ground further exacerbate these risk factors. This dissertation investigates the behavior of buildings with different configurations, including step back, step back set back, and set back buildings, using the structural analysis tool STAAD Pro. Dynamic analysis, specifically response spectrum analysis, is performed to assess their performance under earthquake conditions. The study reveals that certain building configurations exhibit more effective responses to seismic events depending on whether the ground is sloping or level. Given the varying column heights inherent in buildings on sloping ground, detailed analysis is essential to determine the most suitable building configurations for enhanced safety and stability in such environments. This research aims to provide insights into optimal design strategies for mitigating seismic risks in hilly regions, contributing to the development of safer, more resilient infrastructure
