General plastic-hinge is evaluated by full perfect elastoplasticity type shown in Figure l. But it is difficult to make the location of plastic-hinge in actuality. The stress increases while bearing gentle slope after expressing full plastic endurance. As above, the separation between the evaluate and the actual behavior is a problem of present structures. In this study, we study plastic-hinge developed by stick-slip of high-strength-bolts-connection to match the actual behavior and full perfect elastoplasticity type behavior. We investigated correspondence with the behavior of general plastic-hinge through partial processing experiment.
