We present the bearing joint using half-moon-shaped bearing bolt for jointing high-strength members. In order to use the bearing joint, the strength evaluation formula should be required, Hence, in thie study, Shearing thest and F.E.M analysis of high-strength bolt and half-moon-shaped bearing bolt were performed to propose shear yield strength formulas. Also, the influence of deference of directions of enalarged diameter on the shear strength was investigated. From thst results, it is pointed our that the correction factor of the strength evalutation formula of the half-moon-shaped bearing bolt of steel grade 4T and 10T is 1.2 and 0.8 respectively.
