| dc.description.abstract | Railway track irregularities consist of a deviation of the inside edge of the rail from the ideal geometric rail contour and may occur even during the passage of the vehicle at a very low speed. Track irregularities can influence the dynamic behaviour of railways bridges and increase dynamic load effects. This paper addresses the influence of different irregularities on the dynamic behaviour of a medium span bridge. Random irregularities, continuous all over the rail, are considered. The maximum response of the bridge, displacements and accelerations, at the mid span is calculated. For these calculations the dynamic model of the ballast track, present in the ERRI studies, is used and the response of the ballast is also analysed. | por |
