Abstract This paper is devoted to track-bridge interaction phenomena in railway bridges of short
simply-supported (SS) spans composed by ballasted tracks. These structures may experience
high vertical acceleration levels under operating conditions. In particular, the coupling effect
exerted by the ballast track shared by structural parts that are theoretically independent, such
as consecutive simply-supported spans or twin adjacent single-track decks, is investigated.
Experimental evidence shows that in these cases there may be an important vibration
transmission from the loaded to the unloaded track, and that the interlocked ballast granules
couple some of the lowest modes of… More >
