| Abstract: | Based on analyzing the law of the rigidity change of reinforced concrete beam strengthened with carbon fiber sheet(CFS),it is systematically set up the simplified formulas of the rigidity of reinforced concrete beam strengthened with CFS with various loadsby the analytic method.Meanwhile,these formulas arerelated to "The Technical Code of Strengthening Reinforced Concrete with Carbon Fiber Sheet" which are convenient to perfect the design of strengthening projects. |
