Abstract: India has had four of the world’s most destructive earthquakes in the past ten years, and our country is often rocked by earthquakes of low to moderate intensity. Since many buildings were severely damaged or collapsed, it has sparked debate about whether framed constructions are sufficiently sturdy to withstand significant vibrations. As a result, the strength or ability of existing reinforced concrete structures to withstand seismic loads can be evaluated. The performance level of earthquake-prone buildings is evaluated using a performance-based design. One seismic technique for assessing a building’s performance level is push-over analysis. It is possible to determine whether damage occurs at the member or structure level using pushover analysis. The study employs pushover analysis, as outlined in the Applied Technology Council (ATC) – 4, a seismic assessment technique, to evaluate the ability of 20-story buildings in Seismic Zone III (with complex soil characteristics) to resist earthquake-induced forces. The primary objective was to assess the performance of structures reinforced with different fibre-reinforced polymer (FRP) materials, including aramid, glass, and carbon fibres, which are known for their high flexibility and strength in seismically active regions. To determine the optimal fibre-reinforced polymer configuration, the study considers the following parameters: pushover curve, target displacement, story shear, period, maximum story displacement, and story drift, all of which are evaluated independently through pushover analysis. Through the pushover analysis method, the research discovers that FRP wrapping can significantly improve the seismic performance of reinforced concrete buildings. The findings aim to enhance building design practices by recommending fibre-reinforced polymer configurations that improve earthquake resistance, ensuring future constructions are better equipped to handle seismic activity.
