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"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/7223", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2025-06-19"}, "publish_date": "2025-06-19", "publish_status": "0", "recid": "7223", "relation": {}, "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_shared_id": -1}
