Paper Title:
Vehicle-Bridge Coupled Vibration on Concrete-Filled Steel Tubular Arch Bridge
  Abstract

This paper studies the dynamic response and the impact factor of the concrete-filled steel tubular (CFST) arch bridge named Hejiang River Bridge under the moving vehicles. Research shows that the impact factor of CFST arch bridge at the vault and 1/4 arch rib is greatly influenced by the road surface roughness (RSR), and it is increased with the grade of RSR increases, meanwhile it is different at apiece section position of the arch bridge. The impact factor doesn't vary monotonically with the speed of vehicle, it appears the maximum when the speed of vehicle is between 20-25 km/h and 35-50 km/h, and the impact factors of different cross-sections are not just the same with the changing regularity of speed. Therefore, the dynamic characteristics of different structural components should be calculated in designing CFST arch bridge for discrepant dynamic characteristics of various constructional elements.
