Comparison of Static Pushover Analysis in the Case of Small and Large Deformation with Time History Analysis using Flexibility-Based Model for an Existing Structure

Abstract

This work presents the nonlinear methods of analyses for seismic design of structures. The first method is the nonlinear pushover procedure, which is based on the N2 method. The second method is the classical nonlinear time history analysis. The objective of this paper is to make a comparative study of an existing reinforced concrete building in Bonefro, Italy between static nonlinear analysis and time history analysis using flexibility-based finite element, and the sensitivity of the time history analyses to the seismic parameters through Z_Soil; an engineering software based on the finite-element method.
