Analysis of Mechanical Characteristics of the Through CFST Arch Bridge

Shi Ming-xing

Abstract

According to the structural characteristics of the long-span through CFST(concrete-filled steel tube) arch bridge(Gechougou main bridge in Shaanxi),the finite element software Midas is used to calculate the axis force,shearing force,bending moment,and all the coefficients of stability and safety.We have analyzed and discussed the static,dynamic and stable characteristics of the bridge,for they play a great role for its design and construction.Significant technical parameters and basic statistics are given here for its detection and maintenance.They can be used as references in building similar arch bridges.
