Effects of CFRP Strengthening on Dynamic and Fatigue Responses of Composite Bridge

Table 4

Dynamic responses of unstrengthened composite bridges.

Number of steel girders	Direction of moving trucks	Max. deflection (m)	Max. principal stress (MPa)

	Dual lane with the same directions	0.0151	78.5
	Dual lane with opposite directions	0.0151	78.5
5	Single lane	0.0093	46.5
	Dual lane with the same directions	0.0097	47.5
	Dual lane with opposite directions	0.0097	47.5
