| Abstract: | The static test is carried out on four RC beams strengthened by BFRP sheets and one common RC beam for comparison by the way of two-point symmetric localized loading.It observed and analyzed the whole failure process,the distributed characteristic of strains,carrying capacity and ductility,and analyzed the influence of the layer number of the BF and the way of gluing.Experiments showed reinforced concrete beam strengthened with BFRP can satisty reinforced design standards. |

| Keywords: | BFRP reinforced concrete beam the way of gluing ultimate flexural-capacity |
