Abstract: This study deals with the deformation and failure behavior of concrete-filled CFRP box beams under four point bending and axial load. Various parameters such as fiber volume proportion, concrete strength and ratio of bending moment to axial load were examined in the past experiment. A finite element analysis is carried out to confirm the deformation and failure behavior. It is shown that the deformation is affected by the interface and confined effect of CFRP, and the failure is caused by a combination stress. Based on the results of the analysis, a deformation and a failure load caluculation method are developed. Finally, the results of the methods are compared with the experimental results.
