Some three-dimensional base isolation systems have been studied for the application to the nuclear facilities such as a FBR, but have not been made practical yet. The reason is that the loading capacity of the vertical isolation device was not sufficient, and that a rocking motion could not effectively be suppressed. In this paper, we propose a new 3-dimensional base isolation system equipped with hydraulic mechanism for the vertical isolation and the suppression of a rocking motion. A scale model of the proposed system was designed, and the characteristic of the restoring force was examined by static loading test. Shaking table tests using a scale building model were also carried out to confirm experimentally the performance of the vertical isolation and suppressing a rocking motion. The test results were satisfactory and the effectiveness of the system was confirmed.
