| Abstract: | This article presents the carrying-out of the numerical simulation of the enhanced flexural performance of the concrete beams prestressed carbon fiber sheet of large commercial finite dement software ANSYS/Civil. It analyzes the mechanics properties of ordinary RC beam, carbon fiber enhanced RE beam, the bending proof carrying capacity of prestressed carbon fiber enhanced RC beam, the stress course of reinforced steel, the deflection proof course of RC beam. The finding reveals that bonding prestressed carbon fiber sheet is more capable to relax the stress on the steel concrete and enhance the stress of RC beams. |
