Summary

This paper describes the global and local dynamic effects induced by traffic on the Alverca railway viaduct, located in the Portuguese railway network. For this purpose, three-dimensional finite element numerical models of the viaduct, including the track, and train were developed. The dynamic response was obtained using the TBI software which efficiently performed the dynamic analyses considering the train-structure interaction including track irregularities. The validation of the numerical models was performed through a comparison between numerical and experimental dynamic responses, in terms of displacements and acceleration of the viaduct deck for the passage of the Alfa Pendular train. The experimental response, obtained from a dynamic test under railway traffic revealed a very good agreement with the numerical response.
