Prediction Of Structure-borne Vibrations Induced Into Large Structures By Train Transit

In this work, an efficient approach based on numerical simulation and able to evaluate structural noise due to rail transit in large civil structures, is presented. The dynamic analysis is conducted first considering the track and that part of the structure directly interacting with the track system. Subsequently, the forces transmitted by the track system are applied to an extended model of the structure, in order to evaluate the propagation of structural noise.
