Behaviour under static loading of metallic beams reinforced with a bonded CFRP plate
Behaviour under static loading of metallic beams reinforced with a bonded CFRP plate
CFRP plates have been employed widely in the repair and upgrading of bridges and building in recent years. When they are used in the upgrading of metallic beams, the weakest link is the adhesive bonding, and plate peel is the most important failure mode due to the high stress concentration at the end of the plates. This paper presents the results of a study on the influencing factors on the strengthen of the metallic beams reinforced by different types of CFRP plates, the effects of the tapers at the plate ends and of the spew fillets beyond the plate ends. The test results also validate the theoretical results of stress analysis. The use of longer and tapered plates is suggested as a solution for improvement.

Abstract
CFRP plates have been employed widely in the repair and upgrading of bridges and building in recent years. When they are used in the upgrading of metallic beams, the weakest link is the adhesive bonding, and plate peel is the most important failure mode due to the high stress concentration at the end of the plates. This paper presents the results of a study on the influencing factors on the strengthen of the metallic beams reinforced by different types of CFRP plates, the effects of the tapers at the plate ends and of the spew fillets beyond the plate ends. The test results also validate the theoretical results of stress analysis. The use of longer and tapered plates is suggested as a solution for improvement.
