High-Speed Train Passage Effects in Buildings: Vibration Assessment and Isolation

Abstract eng:
This paper analyses train induced vibration in buildings. Emission, transmission and immission mechanisms are considered rigorously. Track-ground-building interaction have been studied, concluding that maximum vibration levels are achieved in the floors of the structure. Building induced vibration due to an impulsive load applied at the track have been analysed. The results show an amplification of the structure response around the natural frequencies. Also, an attenuation in the medium-high range frequency is found. Finally, the effects produced by the high speed trains have been investigated. The conclusions show that vibration levels could exceed the limits set by the standards. In theses cases, corrective actions are required. Effectiveness of isolated track systems is evaluated
