The authors have developed a tensile force strengthening method using bonded carbon fiber reinforced plastic (CFRP) plate to enhance the life of existing building.In this study, performs dynamic fatigue tests on rehabilitated steel beam bonding CFRP plates to reveal fatigue properties of the adhesive and examines fatigue fracture properties of adhesive on cyclic loading. In previous paper, performed preliminary fatigue test for performing adhesive fatigue test to reveal the fatigue properties of adhesive. In this paper,reports investigating the validity of the yield condition in the fatigue limit diagram of the adhesive, which is calculated in the previous studies. The result showed that yield conditions shown in previous studies is reasonable.
