A Comparative Analysis of Multistory Building Seismic Analysis in Various Seismic Zones

Abstract

Given the limited area available and the increasing population, multi-story structures are designed to house large numbers of people in cramped quarters. Construction of multi-story structures for residential and commercial purposes became necessary as a result of the population increase and the industrial revolution, which led to a migration of people from rural to urban areas. All of the towering structures collapse because they are not built strong enough to withstand lateral loads. A building's intrinsic frequency, damping factor, kind of base, importance, and structural ductility are just a few of the factors that go into making a structure that can sustain seismic pressures. Structures developed for ductility must be built for lower lateral loads since they offer superior moment distribution qualities. In order to design earthquake-resistant structures, it is crucial to comprehend seismic analysis and provide safety against the seismic pressures of multi-story buildings. For the seismic investigation, consideration was given to both a conventional and a unique moment-resisting frame. In the current study, a G + 8 story reinforced concrete (RC) structure situated in three different seismic zones had its proportion of longitudinal steel, the details of the reinforcement, and the design base shear analyzed. Seismic zones III, IV, and V were assessed for the structure in compliance with IS 1893 (Part 1): 2016 requirements. The base shear rose as the seismic zone changed from III to V, according to the results.
