Reinforcement Design Calculation Analysis of the CFST Arch Bridge

Based on one calculation example, the stress analysis is given to the CFST arch bridge which has been reinforced. The calculation results reveal that the bridge can meet the demand of the design load after maintaining, but the structure's insurance isn't very enough., which should be paid more attention. On the foundation of statics analysis, but also analyzed the stability and the dynamic performance of this CFST arch bridge, the analysis result indicates that the whole stability of the bridge is relatively good.
