In this study, a real-scale specimen of Steel-Confined Prestressed Concrete (SCP) composite girder was tested in a three points bending. Furthermore, vibration tests were performed to verify the dynamic stability of the SCP composite girder for railway bridges. The results of the experimental test were similar to stable rigidity behavior until the static actuator limit load (6300 kN). That is, the SCP composite girder showed a stable rigidity behavior in the ultimate load (3,174 kN) as well as the service load (1,076 kN). Finally, the possibility of resonance of the SCP composite girder has been found to be low.
