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

Figure 2

Comparison between right singular vectors, extracted by means of SVD, and modal responses of a 4-DOF share-type frame in free vibration, with reference to the example at Section 5.1.3. For an effective comparison, the vectors are both normalized to the maximum value and only the first 100 terms are plotted.
