A Method for Prediction of Structure-borne Noise Radiated from Concrete Railway Viaducts

摘要

Prediction of structure-borne noise has been a significant issue for railway viaducts, since it causes an excessive degree of noise attributable to structural member vibration. A new method of flexural vibration analysis expanded to cover whole structure for the prediction of structure-borne noise has therefore been developed. After calculation and measurement of noise in the vicinity of a floor slab of a concrete viaduct constructed on a Shinkansen line, it was revealed that the proposed method can be used as a practical means for predicting structure-borne noise.
