| Abstract: | To affix the CFRP is a new kind of technique to reinforce concrete construction. This paper testifies that the beam strengthened with CFRP can enhance the bearing capacity, stiffness and the final deflection of beam and can limit developing of cracks of the beam with increment of layers of CFRP, contrasted beam strengthened with different layers of CFRP. The method of stick CFRP got up great effect of reinforce. |

| Keywords: | carbon fiber reinforced polymer laminate (CFRP) beams under flexure strengthen bearing capacity stiffness ductility fracture |
