| Abstract: | In this paper,the experiments on right sectional bending resistance nature and structural damage pattern of the RC beams strengthened by bonding CFRP partially are studied.The the experiment methods on right section of RC beams strengthened by bonding CFRP partially are introduced,and the non-cohensive length of CFRP effect on structural damage pattern,bending resistance nature and weighted performance of tention reinforcement and CFRP are discussed.The results demonstrate that the way of using bonding CFRP partially to strengthen right section of RC beams can effectively increase structural bending resistance nature and improve structural damage pattern which has good value of popularization and application. |
