A Universal Fast Algorithm for Sensitivity-Based Structural Damage Detection

Table 5

Comparisons of the estimated damage parameters by the original generalized flexibility sensitivity method and the fast algorithm (Example 3).

Element no.	True damage reduction	Damage parameters obtained in [17]	Damage parameters computed by the universal fast algorithm
2	0.15	0.1777 (18%)	0.1509 (0.6%)↓
11	0.2	0.2564 (28.2%)	0.2041 (2.1%)↓
19	0.1	0.1120 (12%)	0.1120 (12%)

∗The value in bracket denotes the comparative error between the calculated value and the true value. “↓” denotes the decrease in error.
