Nonlinearity Stability Analysis of Semi-supported CFST Arch Bridge

Huang Zhi-jin

Abstract

A three-dimensional finite element model for Shuanglong Bridge,which is a half-through concrete filled steel tubular(CFST) arch bridge,was established by using the universal finite element program.The stability safety coefficients of the structure of the bridge were calculated through the application of the finite element analysis software.The instability characteristics of the bridge were analyzed.
