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":"\u51fa\u7248\u8005","attribute_value_mlt":[{"subitem_publisher":"\u793e\u56e3\u6cd5\u4eba \u571f\u6728\u5b66\u4f1a"}]},"item_creator":{"attribute_name":"\u8457\u8005","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"S., Beskhyroun"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"T., Oshima"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"S., Mikami"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"T., Yamazaki"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"\u30d5\u30a1\u30a4\u30eb\u60c5\u5831","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-11-22"}],"displaytype":"detail","filename":"8669692-6.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","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":"\u30ad\u30fc\u30ef\u30fc\u30c9","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":"\u8a00\u8a9e","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"\u8cc7\u6e90\u30bf\u30a4\u30d7","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":"\u30bf\u30a4\u30c8\u30eb","attribute_value_mlt":[{"subitem_title":"A Numerical Study of Structural Damage Dectection using Changes in the Curvature of Power Spectral Density"}]},"item_type_id":"3","owner":"1","path":["1"],"pubdate":{"attribute_name":"\u516c\u958b\u65e5","attribute_value":"2007-05-09"},"publish_date":"2007-05-09","publish_status":"0","recid":"7138","relation_version_is_last":true,"title":["A Numerical Study of Structural Damage Dectection using Changes in the Curvature of Power Spectral Density"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2021-09-07T05:12:57.895769+00:00"}
