          <datacite:description xml:lang="ja" descriptionType="Abstract">本研究は、（国研）日本原子力研究開発機構と（国研）防災科学技術研究所との共同研究です。
本研究の目的は、浮体免震建屋の安定性評価に資するため、実際に土槽を用いたプールに浮体免震機構を付与した建屋を浮かべ振動実験を実施し浮体免震建屋の免震性能の実証することです。
加振試験の結果、Air CavityとOrificeを設置した浮体免震構造により、その免震効果を実証できました。</datacite:description>
          <datacite:description xml:lang="en" descriptionType="Abstract">This study is a joint research between the Japan Atomic Energy Agency (JAEA) and the National Research Institute for Earth Science and Disaster Resilience (NIED).
The purpose of this research is to conduct a series of vibrational shaking tests to evaluate the seismic isolation performance of a floating seismically isolated structure using a floating body equipped with a floating seismic isolation mechanism in a pool. 
The results of the tests demonstrated the seismic isolation effect of the floating seismic isolation structure with air cavity and orifice.</datacite:description>
