Hardening and Rehabilitation of Concrete Structures Using Carbon Fiber Reinforced Plastics (CFRP).

Abstract

Carbon Fiber Reinforced Plastic (CFRP) panels were externally bonded to conventionally reinforced steel concrete beams. The CFRP beams were statically tested to their maximum load in a third-point loading device. Elastic-plastic section analyses and a numerical Finite Element Method (FEM) analysis were performed on the beams. Good agreement between the section analysis and the experiment was obtained. Considerable strength enhancement was obtained when the CFRP was added to the bottom of concrete beams with tensile steel reinforcement of less than one percent. For beams with less than one percent steel and CFRP, the failure was by delamination between the CFRP and the adhesive. Improvements in bond strength between the CFRP and adhesive is needed to increase the strength enhancement. jg p3
