Abstract
In order to analyze effectively the response of the members of a railway reinforced concrete rigid frame viaduct to the vibration, a new analysis method was developed. It divides the whole railway system into a vehicle / track model, and a track / structure model. These models were used to examine the influence of various vehicle, track and structure parameters on structural member vibration. The dominant factors were quantified for each frequency concerning the response of the center slab at a train speed of 270 km/h.
