Abstract:
A numerical model was developed to investigate
the flexural performance of Carbon Fibre Reinforced Polymer
(CFRP) strengthened concrete curved beams subjected to outof-
plane bending. In this study, near surface mounted (NSM)
technique has been used to strengthen the curved beams due to
easy of application in curved beams subjected to out-of-plane
bending. A commercially available finite element analysis
software was used to simulate a numerical model and a nonlinear
analysis was carried out. Alternative bonding
arrangements were considered. The results indicate the highest
strength performance in the curved beams with CFRP strip
bonded in the radial direction of the beams. Further, it was
revealed that the CFRP thickness, Elastic Modulus of CFRP,
Concrete Grade, and the beam curvature affect the strength
enhancement.
