For effective conservation of irrigation system, it is necessary to be protection of degradation effects of structural materials using composite materials, such as steel sheet pile-concrete composite. In this study, evaluation of mechanical properties of steel sheet pile-concrete composite in bending test is proposed by applying acoustic emission (AE) method. The deteriorated characteristic of steel sheet pile in service was measured by ultrasonic test. The fracture process of steel sheet pile-concrete composite was analyzed by AE parameters, such as the Calm ratio. The Calm ratio derived from the AE generation behavior in load-displacement behavior in bending test. By calculating the Calm ratio from AE data, characteristics of fracture process of composite material is successfully evaluated.","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"162710","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Suzuki, Tetsuya"}]},{"nameIdentifiers":[{"nameIdentifier":"162711","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yamagishi, Shuntaro"}]},{"nameIdentifiers":[{"nameIdentifier":"162712","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Morii, Toshihiro"}]},{"nameIdentifiers":[{"nameIdentifier":"162713","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kawai, Takayuki"}]}]},"item_7_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"新潟大学農学部"}]},"item_7_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_7_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00183393","subitem_source_identifier_type":"NCID"}]},"item_7_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03858634","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"鈴木, 哲也"}],"nameIdentifiers":[{"nameIdentifier":"162706","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山岸, 俊太朗"}],"nameIdentifiers":[{"nameIdentifier":"162707","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森井, 俊広"}],"nameIdentifiers":[{"nameIdentifier":"162708","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"河合, 隆行"}],"nameIdentifiers":[{"nameIdentifier":"162709","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-08-20"}],"displaytype":"detail","filename":"65(2)_165-169.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"65(2)_165-169.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/28307/files/65(2)_165-169.pdf"},"version_id":"f19eb8f0-4321-4bad-8701-f8fe06369e1e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"鋼矢板","subitem_subject_scheme":"Other"},{"subitem_subject":"腐食","subitem_subject_scheme":"Other"},{"subitem_subject":"鋼矢板-コンクリート複合材料","subitem_subject_scheme":"Other"},{"subitem_subject":"力学特性","subitem_subject_scheme":"Other"},{"subitem_subject":"AE (Acoustic Emission)","subitem_subject_scheme":"Other"},{"subitem_subject":"Steel sheet pile","subitem_subject_scheme":"Other"},{"subitem_subject":"Corrode","subitem_subject_scheme":"Other"},{"subitem_subject":"Pile-concrete composite","subitem_subject_scheme":"Other"},{"subitem_subject":"Mechanical properties","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":"老朽化農業用排水路の鋼矢板-コンクリート複合材による保全に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"老朽化農業用排水路の鋼矢板-コンクリート複合材による保全に関する研究"},{"subitem_title":"老朽化農業用排水路の鋼矢板-コンクリート複合材による保全に関する研究","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","1591"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-05-29"},"publish_date":"2013-05-29","publish_status":"0","recid":"28307","relation_version_is_last":true,"title":["老朽化農業用排水路の鋼矢板-コンクリート複合材による保全に関する研究"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:58:20.482334+00:00"}
