(1 China Academy of Building Research, Beijing 100013, China; 2 Beijing Jiaotong University, Beijing 100044, China)Abstract: A comparison of RC beams strengthened by CFRP flexural design codes of China, American and British was introduced, including the general restrictions, assumptions, design principles, existing strain of beam bottom before strengthening and failure modes of CFRP flexural strengthening for RC beams. In addition, an example to check the different of these codes was given.
Keywords: CFRP; flexural capacity; China,American and British; failure modes; existing strain
