One of the main reasons for these disruptions is the detachment of pipe joints. To verify and validate a measure against the detachment of the joints, a large-scale shaking table experiment was conducted in collaboration with Kanazawa University and Taisei Kiko Co., Ltd. A test specimen was constructed by embedding “seismically reinforced piping” and “unreinforced piping” into a large steel soil container. The seismically reinforced piping incorporated seismic reinforcement products such as fittings to prevent joint disengagement. By applying excitation using E-Defense to collapse the ground, the behavior of the pipes and joints under conditions of significant ground deformations was investigated. A sinusoidal input motion with a maximum of 750 Gal was used. The experiment concluded that the ground collapsed, and significant ground displacement acted on the embedded pipes, and the unreinforced joints completely pulled out, while the seismic reinforcement joints maintained their functionality.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}, {"subitem_description": "データ取得：2021年　", "subitem_description_language": "ja", "subitem_description_type": "Other"}, {"subitem_description": "Data acquisition period : 2021", "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": "2023-10-30"}]}, "item_1617186783814": {"attribute_name": "識別子", "attribute_value_mlt": [{"subitem_identifier_type": "DOI", "subitem_identifier_uri": "10.17598/NIED.0020-E202102"}]}, "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": "水道管路の耐震補強継手の大型振動台実験", "item_type_id": "40006", "owner": "7", "path": ["1749778844647"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/7234", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2025-06-19"}, "publish_date": "2025-06-19", "publish_status": "0", "recid": "7234", "relation": {}, "relation_version_is_last": true, "title": ["水道管路の耐震補強継手の大型振動台実験"], "weko_shared_id": -1}
