Analysis of Dynamic Properties of a Continuous Beam and Arch Bridge with Spans (60+128+60)m on Passenger Dedicated Railway

Taking a continuous beam and arch bridge with spans (60+128+60) m on high-speed passenger dedicated railway as the research object,this paper calculates natural vibration property of the type of the bridge by means of spatial finite element analysis model,makes a study of influences of the cross strut stiffness and arch rib cross section types on the vibration property and also evaluates various dynamic properties of the bridge,train traveling safety and passenger comfort.
