Abstract
In order to analyze effectively the vibration response of the structure members of railway reinforced concrete viaducts, we have developed a new analysis method. It divides the whole railway system into vehicles/track model, and the track/structure model. Using these models, we examined the influence of various parameters of the vehicle, track and structure on the structure member vibration. As a result, the following has become clear. For example, for 20Hz or more, unsprung wheelset mass has a great influence on response of structure member. For 20-100Hz and 150Hz or more, rail surface roughness, for 60Hz or more, the stiffness of the rail pad, for less than 60Hz, the stiffness of the slab of structure and so on, have great influence on structure member vibration respectively.
