Shaking tests were conducted using seismic waveforms such as the 1995 Hyogoken-Nanbu Earthquake (JR Takatori record). 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 of their original values under strong ground motions observed in past earthquakes, thereby achieving the target performance goals.\"\"\"","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"データ取得：2017年　","subitem_description_language":"ja","subitem_description_type":"Other"},{"subitem_description":"Data acquisition period : 2017","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":"2019"}]},"item_1617186783814":{"attribute_name":"識別子","attribute_value_mlt":[{"subitem_identifier_type":"DOI","subitem_identifier_uri":"10.17598/NIED.0020-E201701"}]},"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":"小型地震絶縁装置の性能データ取得試験","item_type_id":"40006","owner":"7","path":["1749778844647"],"publish_date":"2025-06-19","publish_status":"0","recid":"7217","relation_version_is_last":true,"title":["小型地震絶縁装置の性能データ取得試験"],"weko_creator_id":"7","weko_shared_id":-1},"updated":"2025-06-23T05:38:55.084548+00:00"}
