Summary

As a countermeasure against structure-borne noise of steel railway bridge, we developed a new type silent steel railway bridge equipped with floating ladder track and floating reinforced concrete deck. As a result of the train running test, it was apparent that the new steel railway bridge with double floating system has reduced vibration velocity level of 10.5dB(A) at the main girder webs as compared with a steel railway bridge which has directly fastened tracks.
