The patch plate reinforcement is currently being designed based on the crosssectional area ratio, but in reality, the load sharing ratio of the patch plate does not match the cross-sectional area ratio. In this study, we discussed the slip load and yield load of patch plate reinforcement which is applied by high-strength stud bolt and high-strength bolt. In addition, focusing on the load sharing ratio of the patch plate, we performed the parametric analysis, and we elucidated the mechanism of the patch plate load transmission, and the effects of the number of bolts, axial force, bolt arrangement, patch plate thickness.
