Title: Concrete Repair with CFRP
Author(s): Nabil F. Grace
Publication: Concrete International
Appears on pages(s): 45-51
Keywords: Durability; external-bond; freezing and thawing; retrofit.
Abstract:Carbon fiber-reinforced polymers (CFRP) are currently used worldwide to retrofit and repair structurally deficient infrastructure such as bridges and buildings. When reinforced concrete (RC) members are strengthened with externally bonded CFRP, the bond between the CFRP and RC substrate significantly affects the member’s load-carrying capacity. This article presents the effects of adverse environmental conditions on the deflections and ultimate load-carrying capacities of beams strengthened with externally-bonded CFRP. The author proposes strength reduction factors associated with various independent environmental conditions.
