As a result of the subsequent vibration measurement at the site, the main cause of the crack was identified as Karman vortex-induced excitation. However, vibrations were also observed in the wind speed range of 7-8 m/s, which was lower than the resonance wind speed of Karman vortex-induced excitation. Conventionally, according to the results from a wind tunnel test using a side ratio of B/D=2-8 (B: along-wind length, D: cross-wind length), the motion-induced vortex excitation was confirmed. However, the side ratio of the section of the bracing member is B/D=1.18, and the motion-induced vortex excitation in the case of this side ratio has not yet to be confirmed by the conventional wind tunnel test. Therefore, in this research, a spring-supported test was carried out targeting a rectangular cross section of B/D=1.18. Furthermore, flow visualization was performed and the results of the spring-supported test were discussed. The vibrations in the bracing member with a rectangular cross section (B/D=1.18) of Ikitsuki Bridge generated in the wind speed range of lower than Karman vortex-induced excitation among the aerodynamic vibrations caused by wind were suggested to possibly be motion-induced vortex excitation by experimental results of a spring-supported test and the flow visualization. Further investigation should be undertaken.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_5_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA1630046072","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-16-008E","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構(JAXA)"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"九州工業大学"},{"subitem_text_value":"九州工業大学"},{"subitem_text_value":"九州工業大学"},{"subitem_text_value":"株式会社日立製作所"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Kyushu Institute of Technology"},{"subitem_text_language":"en","subitem_text_value":"Kyushu Institute of Technology"},{"subitem_text_language":"en","subitem_text_value":"Kyushu Institute of Technology"},{"subitem_text_language":"en","subitem_text_value":"Hitachi, Ltd."}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"須田, 健太郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松田, 一俊"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"加藤, 九州男"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"玉井, 佑典"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Suda, Kentaro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsuda, Kazutoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kato, Kusuo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tamai, Yusuke","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-15"}],"displaytype":"detail","filename":"AA1630046072.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1630046072.pdf","url":"https://jaxa.repo.nii.ac.jp/record/3465/files/AA1630046072.pdf"},"version_id":"0de8b702-aae6-4e5b-bcff-c306605aa08f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"bracing member","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"rectangular cross section","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"motion-induced vortex excitation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Karman vortex-induced excitation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"spring supported test","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"flow visualization","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Study on aerodynamic vibrations of a bracing member with a rectangular cross section of a long-spanned truss bridge","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Study on aerodynamic vibrations of a bracing member with a rectangular cross section of a long-spanned truss bridge","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["824","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-05-01"},"publish_date":"2017-05-01","publish_status":"0","recid":"3465","relation_version_is_last":true,"title":["Study on aerodynamic vibrations of a bracing member with a rectangular cross section of a long-spanned truss bridge"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T09:01:34.926174+00:00"}
