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

Table 2

Beam example: norm values for different damage scenarios and 1 to 4 known modes (noise 5%).

Known modes	Damage scenario
	1	2	3	4
1 mode	0.137	0.370	0.425	0.307
2 modes	0.137	0.087	0.093	0.313
3 modes	0.000	0.000	0.025	0.128
4 modes	0.000	0.000	0.000	0.098
