          <datacite:description xml:lang="ja" descriptionType="Abstract">【財団法人電力中央研究所による施設貸与実験】設計地震動レベルおよび設計地震動を超える地震動に対して、免震システムの地震時挙動を把握するため、Ｅ－ディフェンスを用いて、実機により近いスケールでの水平免震システムの振動台実験を実施しました。上部基礎版部と壁構造部から成る上部建屋試験体と、鉛プラグ入り積層ゴム（LRB）を含む免震層から構成されている試験体を作製して、暫定設計地震動や過去の地震における観測地震動を入力しました。実験の結果、設計地震動レベルの加振では、いずれも水平方向に関して加速度応答が低減しましたが、上下応答に関しては応答増幅すること等が確認されています。</datacite:description>
          <datacite:description xml:lang="en" descriptionType="Abstract">【Facility Rental Experiment Conducted by Central Research Institute of Electric Power Industry】To understand the seismic behavior of the isolation system in ground motions exceeding the design seismic motion level and design motions, shake table tests of a horizontally isolated system were conducted using E-Defense at a scale closer to that of the actual structure. A test specimen consisting of an upper building model composed of an upper foundation plate and wall structure, and an isolation layer containing Lead Rubber Bearings (LRB), was constructed. Temporary design seismic motions and observed seismic motions from past earthquakes were input into the test specimen. The experimental results showed that, under design seismic motion levels, the horizontal acceleration response was reduced, while the vertical response exhibited amplification, among other phenomena.</datacite:description>
