When the longitudinal prestressed tendons of the PC girder have the fractures due to the corrosion, there is a risk that the load-carrying capacity of the PC girder reduces significantly without discovering the surface anomaly of the PC girder. The conductive paint monitoring that detects bending cracks that show to the load-carrying capacity reduces, was analyzed the applicability and was constructed on the used bridge in order to on-site test, and was examined the applicability.
