ABSTRACT

ABSTRACT: The communication deals with the SNCF experience of track-bridge interaction. Following items will be successively treated:

– long welded rails: conception, design and current effects on platform – bridges as singular points in the current platform – behaviour of the attach from the track on the bridge deck – dimensioning of structures including track-bridge interaction, preliminary approach and f.e.m. calculation

– associated equipment (joints and dilatation devices) – conception of structure in order to manage the phenomenon – examples of good practices in terms of general design for structures submitted to track-bridge interaction.
