    Many pedestrian overpasses had been constructed based on the standard design and most of such bridges have been in service for over 50 years. These bridges often have corrosion damages at invisible members. Therefore, an efficient damage detection method as the structural health monitoring needs to be developed. In this study, a detailed finite element model was constructed to reproduce the bridge analytically and its vibration characteristics were compared to the measurement results. Furthermore, we investigated the effect of corrosion damage on the modal amplitude of the deck by using a finite element model. As a result of this investigation, it is basically possible to identify the damage location of the deck which by focused modal amplitude ratios of damaged conditions.
