Abstract

This paper introduced the linear and nonlinear stability analysis theory of CFST arch bridge,taking a CFST arch bridge as example,established finite-element analysis model,adopt large general finite element analysis program ANSYS analysed the stability of its construction and operation stage,according to the analysis results point out,nonlinear influence should be considered in the stability analysis of construction and operation stage.
