In this paper, the static behavior of the bolted joint interface is analyzed by the finite element method (FEM) in consideration of the joint inter-face boundary conditions which are adherence, slip-ping and separation. And the characteristics are considered theoretically on the deformation, slip-ping behavior and pressure distribution of the joint interface. The following results are found. The joint interface deformation and slipping displacement are decreased by the enlargement of the plate thickness, bolt head size and coefficient of friction on the interface. And the separate area of the joint interface is also decreased and the pressure is distributed more uniformly. Independently of the plate thickness, the half angle of the pressure cone is constant. The effective area of the connecting force increases in proportion as the bolt head diameter and coefficient of friction on the interface increase. But the area does not increase so large as the increment of the bolt head diameter. The joint interface deformation is influenced more effectively by the material of the base than that of the , plate. The effective area of the connecting force increases in proportion as the Young's modulus of the plate increases and in the case of the base, it decreases.
