In this study, the stress transmission between main and patch plates in the patch plate repair method by the combined joint of adhesive and high-strength bolt friction joints was focused on. The uniaxial tensile tests and finite element analysis were carried out for the defective steel plates repaired by the patch plates. As a result of the tensile tests and FE analysis, it was found that the adhesive joints can transmit the stress on the main plate to patch plates mainly even in the combined joint of adhesive and high-strength bolt friction joints until debonding. Therefore, adhesive and high-strength bolted combined joint might be considered as the adhesive joint until debonding.
