On the Use of Singular Vectors for the Flexibility-Based Damage Detection under the Assumption of Unknown Structural Masses

Table 9

Damage indices estimated by SVD-based procedure in case of complete (on the left) and partial identification (on the right, by using only the first vector) on the shear-type frame.
