Carbon Fiber Sheet Reinforcement Of Rc Beams Strengthened With

The rehabilitation of understrengthened reinforced concrete bridges with CFRP laminates is a new technique received considerable attention, and is still in unformed phase. In this paper, the flexural behavior of reinforced concrete T beams strengthened with CFRP laminates was discussed. Based on the experiment of five model T beams, the ultimate flexural capacity of reinforced concrete T beams strengthened with different quantities of CFRP laminates was evaluated, and corresponding design method was formulated, In the experiment and theory analysis, initial loads were considered. Additionally, crack width, midspan deflection and flexural stiffness were investigated and analysised.This paper made a foundation to deeper research the reinforced concrete bridges with CFRP laminates, and provided references to practical bridge rehabilitation project.
