To design the joint, the strength evaluation formula, such as yield and maximum strength of the bearing joint, are required. In particular, high accurate load vs. displacement relation is required to determine the yield strength. Further, large deformation and contact problems must be solved to determine the maximum strength. In this study, F.E.M analysis of high-strength bolted joint is performed. Influence of hole diameter ratio, steel grade and joint plate's end distance to joint plate's yield strength are shown, After that we discuss about the design formulas.
