Research on Mechanical Behavior of Reinforced RC Beams Strengthened with Anti-Arch Method
We analyze the mechanical property of strengthening RC beam by using the method of arch pasting with carbon fiber and directly pasting CFRP through numerical simulation and model test. It explains that strengthening RC girder by using the method of arch can solve the influence of beam's loading by the second time which exists in the method of pasting CFRP in strengthening reinforced concrete beams and it can improve the girder's load when it cracks and the carrying capacity; decreasing the deflection deformation and crack width and gap when the girder carries load; It can make the most use of the character of carbon fiber's high strength. The results play very important role of guiding to engineering.
