Experimental research on the normal section flexural behavior and structural failure mode of partially reinforced CFRP reinforced concrete beams was conducted. The test of normal cross section of CFRP reinforced concrete beams partially bonded with CFRP is introduced. The effect of the unbonded length of partially bonded CFRP on the structural failure modes, structural bending resistance, the behavior of tension reinforcement and CFRP stress performance are also discussed. The results show that the method of partially affixing CFRP to reinforce the normal section of reinforced concrete beam can effectively improve the bending resistance of the structure and change the failure mode of the structure, which has a good promotion and application value.
