The degree of damage, in most case, evaluated as defects of structural surface. In order to maintenance and management of concrete structures, it is desirable to evaluate not only mechanical properties but also detection of defects. In this study, detection of concrete crack in steel sheet pile – concrete composite is proposed by applying infrared thermography method and the semi-variogram analysis of geo-statistics. The semi-variogram analysis is a quantitative evaluation method of the spatial distribution of physical properties. Thus, the semi-variogram appeared different semivariance characteristics depending on the damage degree. The damage level could be reasonably quantified with the semivariogram. By evaluating the damage from the semi-variogram analysis using infrared image, the damage of concrete surface layer is quantitatively evaluated.","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"162551","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kobayashi, Shuichi"}]},{"nameIdentifiers":[{"nameIdentifier":"162552","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Suzuki, Tetsuya"}]},{"nameIdentifiers":[{"nameIdentifier":"162553","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Morii, Toshihiro"}]}]},"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":"小林, 秀一"}],"nameIdentifiers":[{"nameIdentifier":"162548","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鈴木, 哲也"}],"nameIdentifiers":[{"nameIdentifier":"162549","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森井, 俊広"}],"nameIdentifiers":[{"nameIdentifier":"162550","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":"66(2)_147-154.pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"66(2)_147-154.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/28290/files/66(2)_147-154.pdf"},"version_id":"0253884c-46ae-4556-830a-ec4208df4b8c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"空間統計学","subitem_subject_scheme":"Other"},{"subitem_subject":"鋼矢板-コンクリート複合材","subitem_subject_scheme":"Other"},{"subitem_subject":"赤外線サーモグラフィ法","subitem_subject_scheme":"Other"},{"subitem_subject":"セミバリオグラム","subitem_subject_scheme":"Other"},{"subitem_subject":"spatial statistics","subitem_subject_scheme":"Other"},{"subitem_subject":"steel sheet pile – concrete composite","subitem_subject_scheme":"Other"},{"subitem_subject":"infrared thermography method","subitem_subject_scheme":"Other"},{"subitem_subject":"semi-variogram","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":"赤外線画像を用いた鋼矢板-コンクリート複合材に発生したひび割れ検出に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"赤外線画像を用いた鋼矢板-コンクリート複合材に発生したひび割れ検出に関する研究"},{"subitem_title":"赤外線画像を用いた鋼矢板-コンクリート複合材に発生したひび割れ検出に関する研究","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","1589"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-04-07"},"publish_date":"2014-04-07","publish_status":"0","recid":"28290","relation_version_is_last":true,"title":["赤外線画像を用いた鋼矢板-コンクリート複合材に発生したひび割れ検出に関する研究"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:58:13.439132+00:00"}
