In the repair method by high-strength bolted patch plate, the higher slip coefficient between patch plates and steel members is required. However, the quality control of roughness of surface on steel members is difficult on sites. In this study, a combination repair method of high-strength bolts and adhesive bonding is proposed. In order to clarify the effectiveness of proposed method, tensile tests were carried out. As the result of the tensile tests, it was found that the adhesive layer at the ends of patch plate can transfer the stress in main plate to patch plates. Additionally, it was clarified that the load transmission ratio of high-strength bolted joint and adhesive joint at the ends of patch plate.
