SECONDARY FEEDBACK RIDGE ESTIMATION METHOD FOR STRUCTURAL DAMAGE DETECTION

To overcome the ill⁃posed least square problem in sensitivity equations,a secondary feedback ridge estimation method was proposed to detect structural damages based on modal flexibility changes.Modal eigenvalues and mode shapes were utilized to assemble the modal flexibility matrix,which was used to...
