Study on Dynamic Response of Girders under Moving Railway Vehicles with Side Swaying, Rolling and Yawing motions

Studies of railway vehicle-girder interaction, investigations of dynamic response of girders under moving railway vehicles with bouncing and pitching motions, were carried out to data. But dynamic analysis of girders under moving ones with side swaying, rolling and yawing motions is not studied in detail and is necessary for design of high speed railway bridge. The purpose of this paper are to investigate the behavior of response of girders due to a single vehicle of Shinkansen with side swaying, rolling and yawing motions and to make clear the relations of speed parameter and maximum dynamic response. As a result of this investigation, it became clear that the girder was not influenced considerabley by the side swaying, rolling and yawing motions of a railway vehicle.
