Vibrations induced by the circulation of trains in urban surface and underground rail transportation systems may give rise to annoyance to people living and working inside existing buildings and to structural damage. The aim of this work is to illustrate a methodology for the prediction of the vibration levels produced by the railway traffic based on experimental measurements and FE modeling capable of taking into account complex soil conditions and time-varying excitation source. The proposed approach has been applied for the evaluation of the vibrations induced by a new railway line in the city of Palermo, in southern Italy and for the design of suitable countermeasures for the reduction of vibration effects to tolerable levels.

Abstract
Vibrations induced by the circulation of trains in urban surface and underground rail transportation systems may give rise to annoyance to people living and working inside existing buildings and to structural damage. The aim of this work is to illustrate a methodology for the prediction of the vibration levels produced by the railway traffic based on experimental measurements and FE modeling capable of taking into account complex soil conditions and time-varying excitation source. The proposed approach has been applied for the evaluation of the vibrations induced by a new railway line in the city of Palermo, in southern Italy and for the design of suitable countermeasures for the reduction of vibration effects to tolerable levels.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
