Under the effect of a large earthquake, the range of plastic comes into the column and the beam of the frame structure. By using energy dissipation devices, it is possible to reduce the response and the damage of the structure. A friction type damper which was a compact form and had high damping characteristics, was developed. It was made of steel plate, aluminum sliding plate, rubber washer and high tension bolt. To validate the performance of the new damper, the elemental tests and the shaking table test were conducted. In the shaking table test, frame structure composed of full scale member with friction damper was excited by actual seismic wave. As a result, it was found effective and had a high damping performance. This paper mainly reports the results of the shaking table test.
