A Combined Modal Correlation Criterion for Structural Damage Identification with Noisy Modal Data

Figure 13

Frame example: damage prediction of the criterion for the four damage scenarios (no noise). Again, the results using the individual criterion are not good, even with four known eigenmodes, let alone cases with less known eigenmodes (1 to 3). (a) Scenario 1, (b) scenario 2, (c) scenario 3, and (d) scenario 4.
