It broke out the Great Tohoku earthquake in March 2011 was enormous damage in Japan. Japan is well known for earthquakes. Recently it has been reported that long-period seismic waves is danger for high-rise buildings by both the progress of seismograph and increasing in their damage. It has been concerned that capital territory will be expected to occur in the future. Now retrofitting viscos damper as a kind of seismic countermeasure of high-rise buildings is adopted. But it has durability issue that excessive temperature rise of fluid in viscos damper because duration of long-seismic waves is quite long. Therefore we focused on the problems in the present study, we proposed Viscos-Friction Hybrid Damper which is connected existing viscos damper and friction damper with series, to come down absorbed quantity of energy and to progress of durability. In this report, we proposed Viscos-Friction Hybrid Damper and conducted element test which used the test damper to confirm fundamental behavior of it. As a result, it was confirmed that the test damper was satisfied development concept Viscos-Friction Hybrid Damper.
