The observations and analyses made after the major recent earthquakes have shown that such problems exist in joint systems of steel structure commonly used as fracture at weld lines and permanent structural distortion. This paper describes a new joint system named elastic-hinge joint system by the authors. 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 or in structural elements after a severe earthquake. The present simplified experiments and numerical analyses in this paper show that this new joint system has advantages of realization of earthquake resistant steel structure.
