    In this paper, we proposed a new seismic hinge, which was applied to the beam end regions of steel moment resisting frame structures. The hinge consists of a narrow vertical slot which cuts the beam bottom flange, the bolted frictional slippage damper which connects the beam bottom flange cut, and the inclined stiffeners which transfer the beam shear force beyond the vertical slot. It is planned that the frame which has the hinge mechanism does not produce the large plastic deformation at the beam end region, but resists against seismic action with the frictional slipping behavior of the bolted dampers. This paper presents the result of the static and dynamic loading tests on the wide flange steel beams with the bolted frictional slippage damper. The beams with the proposed hinge mechanism behaved with the perfect elasto-plastic type of the load deformation response as planned during the loading.
