Abstract

Hanjiang Northern Bridge is a concrete filled steel tubular (CFST) through leaning-type arch bridge in Chaozhou city of Guangdong Province. Regarding its main span as the research object, considering elastic restricted function of the border span to the main span, the finite element program ANSYS was used to establish a spatial finite element dynamic calculating model of it. 14 operating-condition modes were considered in the finite element method (FEM) analysis process in order to analyze the influences of different modes on dynamic characteristics of the bridge. The calculation results indicate that the CFST leaning-type arch bridge is a flexible structure. The vertical rigidity of the bridge is stronger than the out-surface rigidity of concrete arch rib. Both the out constraint of V-type brace and the flexural rigidity of tie-beam influence dynamic characteristic of the bridge weakly. If increasing transverse displacement at the toe of stable arch or adding the suspender amount, the out-surface rigidity of the arch rib will be increased obviously but the vertical and torsional rigidity won't be changed greatly. The bridge construction status influences the vibration mode greatly.
