Summary:The deterioration of performance of steel structures comes from various reasons. One of main reasons of such deterioration is the corrosion of steel, and the development of a reasonable repair method is demanded. This paper presents the applicability of CFRP adhesion for the repair of corroded steel members. Steel beams with fictitious corrosion repaired by CFRP were tested under bending in order to assess the repair method of corroded steel. As a result, it was confirmed that the stress of corroded steel was improved by patching CFRP.
