Simulation Calculation Analysis of RC Beam Strengthened with Carbon-Fiber by Reverse-Arch Method
Using utilities equipment to make the reinforced concrete girder to generate a kind of reverse-arch radian, then paste CFRP on the under-part of the girder, after the CFRP was maintained, unload, at this time, the CFRP is working together with the primary reinforced concrete girder. Using analysis software ANSYS to simulate this process, comparing with the RC beam strengthened with carbon-fiber directed, a conclusion was got that is the deflection of a RC beam strengthened with carbon-fiber by reverse-arch method is much smaller and the CFRP to bear much loads than the ordinary method. The conclusion can be a reference to the similar projects.
