In the previous study, the authors provided a new beam-column joint system named elastic hinge joint system. This new joint system performs a non-linear elastic restoring force-rotation relation and can materialize origin-oriented frames. And, these abilities can control damage and reduce permanent structural distortion in structures after a severe earthquake. In the elastic hinge joint system, the beam and column members are connected by the long prestressing bolts that go through the beam and column. In the previous study, PC strands was applied to the prestressing bolts. In this paper, the authors paid attention to the aramid fiber ropes as example of new prestressing bolts. It is clarified that the force-strain relation of aramid fiber ropes was characterized by hysteresis loop. The propose of this paper is to clarify the separation and rotation behavior of elastic hinge joint with aramid fiber ropes as the prestressing bolts.
