Abstract
This paper proposes a technique that predict the characteristics of the vibration propagation in a building excited by train running. It is assumed that transformation at the excitation point is created by the bending wave in the slab with the impact of the train running. For estimation of the vibration power, the effective vibration presumption method was attempted focusing on the wave-length of the bending wave of the limited length slab. The scale-model and full-scale experiments, and computer model using FEM were carried out in order to verify this method. The method for predicting the vibration response in the building was examined using transmission-accelerance allowing the detection of the region influenced by the excitation. This method is based on the eaqual interval excitation model which represents multiple excitation points on the rail.
