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_description_194":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_3_full_name_183":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"34627","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Beskhyroun, Sherif","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"34628","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Oshima, Toshiyuki","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"34629","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Mikami, Shuichi","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"34630","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yamazaki, Tomoyuki","nameLang":"en"}]}]},"item_3_publisher_212":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"社団法人 土木学会"}]},"item_3_rights_192":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"社団法人 土木学会, S.
