| Abstract: | The effect of the layers and the way of gluing of CFRP to the RC beams strengthened with CFRP sheets on flexural performance and mechanical performance is studied. The character of destroy and the course of crack of the RC beams strengthened with CFRP sheets are analyzed. And the changes of carrying capacity, flexibility and rigidity are analyzed. The results show the bonded CFRP can effectively increase the flexural rigidity and enhance the flexural performance and durability of the members. |
