 Contact points between two solids are very small we can’t make a sight in Figure 1. We focus on property of High-strength-bolt friction joint, and we propose Beam-Joint-Plastic-Hinge. We examine whether it correspond to Generalized Plastic Hinge. Beam-Joint-Plastic-Hinge is rolling mechanism utilizing slip behavior of High-strength-bolt friction joint, and its forming condition is slipping largely without transitioning bearing-type connection. When cycle large displacement occurs acting large tightening force by High-strength-bolt, surface asperity of friction surface will be broken. This is why state of steel material surface and slip-coefficient will be changed by repeated slip behavior. Plastic-Hinge-Moment which is defined as the moment at the joint when Beam-Joint-Plastic-Hinge is formed, is affected by slip-coefficient. We investigated relationship between state change of steel material surface and slip-coefficient through slip experiment. And disclosed the frictional surface which contribute to improve the evaluation precision of Plastic-Hinge-Moment.
