Multiobjective Optimization Approach for Robust Bridge Damage Identification against Sensor Noise

Damage scenarios.

Scenario	Case	Locations	Damage scenarios
DS1	Single	Node 7	Damage in connection between longitudinal and transverse beams by removing connection plates and bolts at joint, in order to simulate the local loss of stiffness at the connection
	Multiple	Nodes 7, 26
DS2	Single	Node 19	Damage in boundary of deck by adding bolts at connection between pier and deck, in order to simulate the support locking at the top of the bridge pier
	Multiple	Nodes 19, 38
