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":"\u30d5\u30a9\u30fc\u30de\u30c3\u30c8","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_3_full_name_183":{"attribute_name":"\u8457\u8005\u5225\u540d","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":"\u51fa\u7248\u8005","attribute_value_mlt":[{"subitem_publisher":"\u793e\u56e3\u6cd5\u4eba \u571f\u6728\u5b66\u4f1a"}]},"item_3_rights_192":{"attribute_name":"\u6a29\u5229","attribute_value_mlt":[{"subitem_rights":"\u793e\u56e3\u6cd5\u4eba \u571f\u6728\u5b66\u4f1a, S.
