The consistent experimental programs suggest that more progress creep induced by larger prestressing force or elevated temperature at early ages is likely to make the long-term prestress loss smaller. The compressive strength and Young’s modulus of concrete after the creep promotion are larger than those of concrete without creep, while the tensile strength and Young’s modulus are almost the same or decreased when large sustained stress exceeding elastic range is applied. The flexural behavior of the prestressed concrete beam with the creep promotion is not different from that of the beam without the creep at early ages, although the maximum flexural crack width is slightly increased due to the creep promotion. Since it is found that the shear crack propagation is more progressive when the creep is greatly advanced under severe conditions such as at elevated temperature, the appropriate application of the prestressing force to prestressed concrete beam at early ages is indispensible for maintaining the structural performance.","subitem_description_type":"Other"}]},"item_120_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_120_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_120_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"埼玉大学工学部広報委員会"}]},"item_120_source_id_14":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18804446","subitem_source_identifier_type":"ISSN"}]},"item_120_text_27":{"attribute_name":"版","attribute_value_mlt":[{"subitem_text_value":"[出版社版]"}]},"item_120_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"ASAMOTO, Shingo"},{"subitem_text_value":"MAKI, Takeshi"}]},"item_120_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"KY-AN00095842-44-08"}]},"item_120_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"埼玉大学工学部建設工学科"},{"subitem_text_value":"埼玉大学工学部建設工学科"}]},"item_120_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"Department of Civil and Environmental Engineering, Faculty of Engineering, Saitama University"},{"subitem_text_value":"Department of Civil and Environmental Engineering, Faculty of Engineering, Saitama University"}]},"item_120_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"2010"}]},"item_120_version_type_28":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"浅本, 晋吾"},{"creatorName":"アサモト, シンゴ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"牧, 剛史"},{"creatorName":"マキ, タケシ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-24"}],"displaytype":"detail","filename":"KY-AN00095842-44-08.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KY-AN00095842-44-08.pdf","url":"https://sucra.repo.nii.ac.jp/record/16453/files/KY-AN00095842-44-08.pdf"},"version_id":"95961a40-18d7-4058-aaa0-0617979b8a57"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Creep","subitem_subject_scheme":"Other"},{"subitem_subject":"Early ages","subitem_subject_scheme":"Other"},{"subitem_subject":"Prestressed concrete","subitem_subject_scheme":"Other"},{"subitem_subject":"Prestress loss","subitem_subject_scheme":"Other"},{"subitem_subject":"Structural response","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"若材齢時にクリープを促進したプレストレストコンクリート梁のプレストレス減少と構造性能に関する研究＜論文＞","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"若材齢時にクリープを促進したプレストレストコンクリート梁のプレストレス減少と構造性能に関する研究＜論文＞"}]},"item_type_id":"120","owner":"3","path":["523"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-02-24"},"publish_date":"2014-02-24","publish_status":"0","recid":"16453","relation_version_is_last":true,"title":["若材齢時にクリープを促進したプレストレストコンクリート梁のプレストレス減少と構造性能に関する研究＜論文＞"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T09:44:43.466396+00:00"}
