In this paper a numerical study about the influence of soil stiffness on the assessment of vibrations induced by railway traffic in tunnels is performed. A comprehensive [...]

The behaviour of small span railway bridges is known to be particularly difficult to predict due to the complexity of the coupled train-track-bridge system, as well as fo [...]

A vehicle-structure interaction methodology with a nonlinear contact formulation based on contact and target elements has been developed. To solve the dynamic equations o [...]

This paper presents two main parts, encompassing the experimental assessment and the numerical modelling of vibrations induced by railway traffic. Firstly, a global descr [...]

As far as slab tracks are concerned, UIC [1] considers seven different families of structures, regarding the type of slab supporting (punctual or continuous), the constru [...]

Along the track there are zones of abrupt changes in track stiffness such as those at transitions from embankment to bridge, between distinct types of railway, from track [...]

The main objectives of the paper are to evaluate the relevance of the non-linear soil behavior on the track response and to validate the proposed methodology which includ [...]
