Vehicle-induced Vibration of Half-through and Through CFST Arch Bridges

摘要

The road roughness curves and vehicle-induced responses of eight concrete-filled steel tubular(CFST) arch bridges with suspended deck system are obtained by field test. The dynamic analysisconsidering the interaction between vehicle and bridge are carried out by finite element method. Thevehicle-induced vibration analysis of CFST arch bridge is verified by comparing with the measuredacceleration responses. The accelerations and velocities in CFST arch rib and suspended deck arethen analyzed.
