Table 2

Damage scenarios for single-span bridge.

Damage scenario	Damage type	Damage location	Reduction in elastic modulus	Noise
M1-1	Single	4	17%	Nil
M1-2	Multiple	2, 7	4%, 21%	Nil
M1-3	Multiple	3, 5, 6, and 8	12%, 6%, 5%, and 2%	Nil
M1-4	Random	All elements	Random damage in all elements with an average of 5%	Nil
M1-5	Random	All elements	Random damage in all elements with an average of 15%	Nil
M1-6	Estimation of undamaged state	All elements	5% reduction in all elements	Nil
