In order to examine the seismic behavior of Japanese traditional tea ceremony room subjected to an intense earthquake, We have conducted a series of shaking table tests using a full size model of Myouki-an Tai-an in Kyoto the national treasure, the bottom of columns of which are not connected to the foundation. This is one of the most important features of Japanese traditional wooden houses and is assumed that the upper frame may move from the foundation and reduce the damage in the event of a strong earthquake. Following results have been obtained. 1) A half of the Input-energy estimated to dissipate through the friction between bottom of columns and foundation. 2) According to the decrease of the rigidity of the model due to the accumulation of damage, energy absorption due to hysteresis became large compared to that by frictional resistance of the base. 3) The model moved more easily if the vertical acceleration is combined with horizontal components in comparison with the case the vertical acceleration is not exist.
