Nonlinear Pushover Analysis of Multi-Storied Structure Using ETABS Software

Abstract

The nonlinear pushover analysis is a widely used method for assessing the seismic performance of structures. The nonlinear pushover analysis of a multistory structure using ETABS software is presented in this paper. The aim of the study is to evaluate the seismic behavior and capacity of the structure under lateral loads. The study involves modelling the multi-storied structure (G+7) using ETABS software and subjecting it to lateral loads. The pushover analysis is performed using a nonlinear static procedure, where the structure is subjected to increasing lateral loads until failure or collapse. The results obtained from the pushover analysis are then used to evaluate the seismic performance of the structure and identify any potential weaknesses or deficiencies. The study also involves a sensitivity analysis to investigate the effects of different parameters on the structural behavior and capacity. The parameters considered in the analysis include the storey displacement, storey shear, and the storey drift along the height of the structure. The study provides valuable insights into the seismic performance of multistoried structures and highlights the importance of considering nonlinear behavior in the analysis and design of such structures. The results obtained from this study can be used to inform the design of more resilient and robust structures that can better withstand seismic events.
