Bearing Damage Detection of a Bridge under the Uncertain Conditions Based on the Bayesian Framework and Matrix Perturbation Method

Table 1

The damage cases of the continuous beam structure.

Noise level (%)	Temperature variation (reference temperature is 0 (°C))	Case	Damage severity @ element number	Damage severity @ bearing number	Detection goal
3	20	1	50% @ 1	/	E
			30% @ 48
		2	50% @ 1	30% @ 1#	E
		3			E
		4			B and E
		5	50% @ 26	30% @ 1#	B
		6			E
		7			B and E

Note: E and B denote the element damage and bearing damage, respectively.
