Seismic Evaluation of the Performance of Steel Moment Resisting Frame Subjected to Cyclic Loading in Zone Ⅱ, Ⅲ, Ⅳ and Ⅴ

Abstract

All loads, including gravity, wind, and land sliding loads, must be taken into account in the analysis of a structure for an accurate structural design. This research will perform a numerical analysis of a steel moment resistant frame subjected to both concentrated gravity and cyclic stress. We shall study how a gravity load changes the cyclic behavior of a moment-resisting frame. In a moment- resisting frame of a given size, a concentrated load will be applied in the beam's midsection, and lateral cyclic displacement will be generated in accordance with the ATC24 protocol. To assess the results for various seismic parameters, a cyclic diagram for the applied lateral load will be drawn. Using the FEM findings, we will determine how much of an impact gravity load has on the moment-resisting frame in the presence of cyclic displacement. In this work, we compare the results of our analysis across four seismic zones in India.
