In the case of railway bridges through the downtown section is required for noise reduction performance is excellent bridge type. According to this request, the bridge of the noise barrier installation is not required and low vibration is under development. This railway bridge is corrugated steel plates composite lower route bridge. Because the bridge cross-section wraps a train, noise is reduced. In this study, Using a commercial finite element analysis program, the dynamic stability evaluation is performed.
