In this study, a numerical experiment was carried out using a finite element modelling, and the contribution of each member to structure-borne sound was quantitatively clarified. Specifically, the contribution of the overall value at the 25m point on a reinforced concrete (RC) rigid frame viaduct was 73% for the center slab, 10% for the soundproof wall, and 17% for the overhanging slab. In addition, the contribution of the RC rigid frame viaduct and the adjacent RC girders was 67% and 33% respectively, indicating that not only the rigid frame viaduct but also the RC girder may have a relatively large contribution to structure-borne sound along the railway line.
