Dynamic Characteristics of Semi-supported CFST Arch Bridge

Jiang Yueqin

Abstract

The self-vibration parameters for the Shuanglong Bridge,which is a concrete-filled steel tubular arch bridge in Jinhua City,were obtained by means of the finite element model and the experimental simulation.The inherent frequency,mode,damp ratio and impact coefficient of the bridge were obtained by comparing the actual test results with the simulated results.This paper also studied the real-time behavior of the bridge under dynamic loads and judges its maximum load-carrying ability and normal working conditions.
