In order to study the test performance of the concrete-filled CFRP steel tubular (CF-CFRP-ST) beam-column under hysteretic load, 12 specimens were designed. During the test loading, the effects of axial compression ratio and longitudinal CFRP reinforcement coefficient on hysteric load were studied. Based on experimental research, a finite element method for establishing CF-CFRP-ST beam-column is proposed by FE simulation, and the influence of main parameters on performance is studied by this method. The test results show that CFRP and the steel tube can work together well, and the local buckling of specimens is delayed. In addition, the simulation results are in good agreement with the experimental results. Based on the experiment and finite element method, the influence of main parameters on the hysteretic behavior of specimens is studied.
