Spatial Stability Analysis of CFST Arch Bridge

Xin-dai Zuo

Abstract

A method for special stability analysis of a long span concrete filled steel tubular (CFST) arch bridge was developed based on FEM with considerations of both geometrical non()linearity and material nonlinearity. Using the method, analyses were conducted on the stability during construction and service of the bridge with results providing the basis for the design and construction.
