The vibration measurements of the twenty-storey of reinforced concrete building using base isolation system nearby railway tracks were carried out aiming at establishment of a simplified prediction method of structure borne sound, paying attention to each characteristic of input loss of foundation and vibration propagation in the building. Through these measurements, the characteristics of the loss of foundation and the vibration propagation of the building were clarified and it was shown that multi-degree-of-freedom model explains the vibration propagation characteristic well. In addition, parameteric studies of vibration reduction effect by base isolation devises were carried out using this model, and these were found that vibration reduction effect of this building is proper, and the effect was influenced of vertical stiffness of the building and the isolators.
