Abstract:
A lot of RCC structures in seismic zones are unable to withstand earthquakes as a result of rapid expansion in urbanization and the development of more of high rising buildings. Buildings on sloping ground present unique challenges compared to those on flat terrain. Their irregular and asymmetrical designs, necessary for adapting to the slope, can create structural vulnerabilities. On the sloped terrain, buildings often require columns of varying heights to accommodate the gradient, leading to uneven weight distribution and increased stress on certain parts of the structure. The present scenario, buildings are constructed of irregular plans on different terrain and shape due to less availability of space, economic feasibility, and other factors. This work aims to be studying the many building's irregularities along with L- shape, O-shape, H-shape & rectangular shape on different terrain and their behavior during seismic forces. Buildings models are analyzed by Etabs 18 software. The aim is to conduct response spectrum analysis (RSA) on vertically uneven buildings on different terrain based on IS 1893(part 1)-2016. This study focusses on learning the various parameter like base shear, storey drift, and vertical geometry irregularity to be analyzed for seismic force. The adoption of base isolation strategies has become increasingly popular as an effective means of protecting buildings from earthquake threats. This technique involves creating a separation between a building’s structure and the ground motion, allowing the building to move independently during seismic events.The purpose of the study is to show comparative analysis of symmetric buildings and asymmetric buildings of G+5 height in slope terrain and flat terrain. Five storey structures are analyzed here. Space frames constructed from reinforced concrete can effectively withstand tremors or earthquakes, thanks to a non-linear analysis of past seismic events. By the help of ETABS version 18 non-linear software (developed by CSI Ltd), the building is evaluated in accordance with the seismic code IS-1893: 2016.The increasing urbanization and proliferation of high-rise structures in seismic zones have raised critical concerns about the structural integrity of buildings during seismic events. This study delves into the seismic analysis of buildings with various shapes situated on both plain and sloping terrains. Through this study, insights into the seismic performance of irregular structures on both sloping and plain terrains are gained, shedding light on the effectiveness of base isolation strategies in safeguarding these structures against seismic threats.
