Facilities that have been in use for a long time are expected to experience deterioration of their components and piping due to aging, and it is necessary to take appropriate measures to deal with this deterioration. In piping systems, corrosion and other factors can cause thinning deterioration, as one example of aging. Based on the above, to evaluate and verify the effects of deterioration on the seismic response and performance of piping systems, two types of piping system test specimens, a healthy test specimen without deterioration and a reduced-wall-thickness test specimen, were fabricated, mounted on the E-Defense facility, and subjected to simulated seismic motions at the same time. In the experiment, the reduced-wall-thickness test specimen suffered damage due to internal pressure failure associated with the ratchet phenomenon, and thereafter, continued shaking resulted in fatigue cracking damage to the healthy test specimen.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}, {"subitem_description": "データ取得：2010年　", "subitem_description_language": "ja", "subitem_description_type": "Other"}, {"subitem_description": "Data acquisition period : 2010", "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": "2012"}]}, "item_1617186783814": {"attribute_name": "識別子", "attribute_value_mlt": [{"subitem_identifier_type": "DOI", "subitem_identifier_uri": "10.17598/NIED.0020-E201001"}]}, "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": "高経年配管系に対する耐震裕度の定量評価に関する研究", "item_type_id": "40006", "owner": "7", "path": ["1749778844647"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/7181", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2025-06-19"}, "publish_date": "2025-06-19", "publish_status": "0", "recid": "7181", "relation": {}, "relation_version_is_last": true, "title": ["高経年配管系に対する耐震裕度の定量評価に関する研究"], "weko_shared_id": -1}
