Maintenance of concrete structures, damage evaluation is now in agent demand. In this study, damaged concrete samples were examined based on the mechanical properties and X-ray CT images. In the experiments, concrete damage was evaluated by X-ray CT and acoustic emission (AE). Then, concrete damage is evaluated based on AE parameters due to fracture under compression. It is demonstrated that the decrease in mechanical parameters could be evaluated by comparing CT number and AE rate. A relation between AE and damage parameter is correlated.","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"162491","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yamagishi, Shuntaro"}]},{"nameIdentifiers":[{"nameIdentifier":"162492","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Suzuki, Tetsuya"}]},{"nameIdentifiers":[{"nameIdentifier":"162493","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Morii, Yoshihiro"}]}]},"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":"山岸, 俊太朗"}],"nameIdentifiers":[{"nameIdentifier":"162488","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鈴木, 哲也"}],"nameIdentifiers":[{"nameIdentifier":"162489","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森井, 俊広"}],"nameIdentifiers":[{"nameIdentifier":"162490","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":"67(1)_77-82.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"67(1)_77-82.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/28281/files/67(1)_77-82.pdf"},"version_id":"eaaa538e-b55a-449a-9483-53b88d23a05f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"X線CT法","subitem_subject_scheme":"Other"},{"subitem_subject":"コンクリート","subitem_subject_scheme":"Other"},{"subitem_subject":"ひび割れ","subitem_subject_scheme":"Other"},{"subitem_subject":"AE（Acoustic Emission)","subitem_subject_scheme":"Other"},{"subitem_subject":"圧縮強度試験","subitem_subject_scheme":"Other"},{"subitem_subject":"X-ray computed tomography","subitem_subject_scheme":"Other"},{"subitem_subject":"Concrete","subitem_subject_scheme":"Other"},{"subitem_subject":"Crack","subitem_subject_scheme":"Other"},{"subitem_subject":"Acoustic emission","subitem_subject_scheme":"Other"},{"subitem_subject":"Compression test","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":"X 線CT の空間統計処理に基づく損傷コンクリートの特性評価","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"X 線CT の空間統計処理に基づく損傷コンクリートの特性評価"},{"subitem_title":"X 線CT の空間統計処理に基づく損傷コンクリートの特性評価","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","1588"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-10-06"},"publish_date":"2014-10-06","publish_status":"0","recid":"28281","relation_version_is_last":true,"title":["X 線CT の空間統計処理に基づく損傷コンクリートの特性評価"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:58:16.164662+00:00"}
