The mock-up, which combines an air-levitation horizontal seismic isolation device with a vertical seismic isolation system composed of a negative-stiffness spring linkage and coil springs, measures 1.3 m × 1.3 m × h 1.0 m and supports a load of 2,000 kg. Shaking tests were conducted using seismic waveforms such as the 1995 Southern Hyogo Prefecture Earthquake. As a result, the system demonstrated the ability to reduce horizontal accelerations to less than one-tenth and vertical accelerations to less than one-third under strong ground motions observed in past earthquakes, thus achieving the target performance.\"","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"データ取得：2018年","subitem_description_language":"ja","subitem_description_type":"Other"},{"subitem_description":"Data acquisition period : 2018","subitem_description_language":"en","subitem_description_type":"Other"},{"subitem_description":"お問い合わせ：asebi@bosai.go.jp","subitem_description_language":"ja","subitem_description_type":"Other"},{"subitem_description":"inquiry： asebi@bosai.go.jp","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"防災科学技術研究所"},{"subitem_1522300295150":"en","subitem_1522300316516":"National Research Institute for Earth Science and Disaster Resilience"}]},"item_1617186660861":{"attribute_name":"Date","attribute_value_mlt":[{"subitem_1522300695726":"Issued","subitem_1522300722591":"2020"}]},"item_1617186783814":{"attribute_name":"識別子","attribute_value_mlt":[{"subitem_identifier_type":"DOI","subitem_identifier_uri":"10.17598/NIED.0020-E201803"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"dataset","resourceuri":"http://purl.org/coar/resource_type/c_ddb1"}]},"item_1617353299429":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_1522306207484":"isIdenticalTo","subitem_1522306287251":{"subitem_1522306382014":"URI","subitem_1522306436033":"https://asebi.bosai.go.jp/"},"subitem_1523320863692":[{"subitem_1523320867455":"en","subitem_1523320909613":"LOGIN Page for Registered Users"}]}]},"item_title":"小型振動絶縁検証装置の鉛直高負荷化性能確認試験","item_type_id":"40006","owner":"7","path":["1749778844647"],"publish_date":"2025-06-19","publish_status":"0","recid":"7223","relation_version_is_last":true,"title":["小型振動絶縁検証装置の鉛直高負荷化性能確認試験"],"weko_creator_id":"7","weko_shared_id":-1},"updated":"2025-06-23T05:39:18.052660+00:00"}
