Based on changes in Power Spectral Density (PSD), this paper proposes a damage identification technique that detects damage and its location. The method is applied to a finite element model of a three span steel bridge with a concrete deck. Several damage scenarios were introduced to a main girder of the bridge. The method determined the exact damage location. In addition, the results illustrate that changes in the PSD curvature can be a useful tool for continuous monitoring of structural integrity using ambient vibration data. Furthermore, changes in the PSD curvature do not require a very fine grid of measurements to detect and locate damage effectively.", "subitem_description_type": "Abstract"}]}, "item_3_publisher_212": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "社団法人 土木学会"}]}, "item_3_select_195": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "open access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_abf2"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "S., Beskhyroun", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "36262", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "T., Oshima", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "36263", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "S., Mikami", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "36264", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "T., Yamazaki", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "36265", "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": "2016-11-22"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "8669692-6.pdf", "filesize": [{"value": "1.2 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 1200000.0, "url": {"label": "8669692-6.pdf", "url": "https://kitami-it.repo.nii.ac.jp/record/7138/files/8669692-6.pdf"}, "version_id": "b0999cc4-f87b-46ef-99bd-40b7aa977ac0"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "vibration characteristics", "subitem_subject_scheme": "Other"}, {"subitem_subject": "damage detection", "subitem_subject_scheme": "Other"}, {"subitem_subject": "modalproperties", "subitem_subject_scheme": "Other"}, {"subitem_subject": "health monitoring", "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": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "A Numerical Study of Structural Damage Dectection using Changes in the Curvature of Power Spectral Density", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "A Numerical Study of Structural Damage Dectection using Changes in the Curvature of Power Spectral Density", "subitem_title_language": "en"}, {"subitem_title": "パワースペクトル密度曲線の変化を用いた構造欠陥検出の数値解析", "subitem_title_language": "ja"}]}, "item_type_id": "3", "owner": "1", "path": ["86"], "permalink_uri": "https://kitami-it.repo.nii.ac.jp/records/7138", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2007-05-09"}, "publish_date": "2007-05-09", "publish_status": "0", "recid": "7138", "relation": {}, "relation_version_is_last": true, "title": ["A Numerical Study of Structural Damage Dectection using Changes in the Curvature of Power Spectral Density"], "weko_shared_id": -1}
