In designing bolted joints, it is important to examine the clamping effect (the distribution of contact stress) and to estimate the force ratio (the ratio of an increment of bolt axial force to an external load). The clamping force of bolts and the external bending moment are axi-asymmetrical loads, and no investigations treated as axi-asymmetrical loads are made either except some ones reported. In this paper, the clamping effect and the force ratio in the case where clamped parts are circular flanges subjected to external bending moments are analyzed as axi-asymmetrical problems using a three-dimensional theory of elasticity. For verification, experiments are carried out with respect to the distribution of contact stress and the force ratio for the external bending moment (relationship between an increment of bolt axial force to an external bending moment). Analytical results are in a fairly good agreement with experimental ones.
