Demands for diagnostic and monitoring techniques of corrosions on metallic reinforcements which increase the risk of collapse are rising as the number of aged structures are growing. The visual inspection performed in the regular diagnosis of the structures is insufficient to prevent the danger in advance because the corrosions are mainly generated in the interior. In this paper, we propose a new structural health monitoring method for the local and internal corrosion of the structures via time-frequency domain reflectometry (TFDR). The local corrosion can be detected and be localized by TFDR and two indicators for monitoring the corrosion are introduced. The indicators are verified by monitoring experiments of a local corrosion.
