Abstract

For research on the strengthening and repairing technology of the concrete flexural members, mechanical properties and deflection deformation of reinforced concrete flexural members are studied by means of several experiments which are pasted the carbon fiber cloth in tension section. This article made the contrast test reinforced concrete beams and the pasted carbon fiber cloth reinforced concrete beams and conducted the static bending load experiment. This research works on the characteristic parameters of the fiber cloth and cross section area of beams had been done, then the suitable technical parameters of reinforce engineering are given. Based on the flexural experimental of reinforced concrete beam with two ways of paste fiber cloth and two the cross-sections beams, pasting fiber cloth in tensile area of reinforced concrete beam can not only improve the bending capacity of flexural member, but also improve the section flexural stiffness and the crack resistance of the components. The results showed that the bearing capacity of pasted fiber cloth reinforced concrete is obviously improved under the condition of same cross section area. Static bending test results show that the existence of fiber cloth can improve the mechanical performance index of component and slow the development of the cracks generated. The bearing capacity and ductility of the CFRP reinforced concrete beams are better than that of ordinary concrete members. Research and analysis show that the use of carbon fiber cloth can effectively reduce the cross-sectional area of the reinforced concrete beam and steel consumption.
