AB  - Concrete-filled CFRP steel tube (CF-CFRP-ST) structures often suffer from shear 
      loading in practical engineering, such as joints with diagonal braces. To study 
      the shear properties of CF-CFRP-ST, we take the concrete strength and the 
      longitudinal CFRP layers as the main parameters, and static shear tests of 
      overall 9 circular concrete-filled CFRP-steel tube (C-CF-CFRP-ST) and 3 circular 
      concrete-filled steel tube (C-CFST) are carried out. The research is carried out 
      from two aspects: experiment and finite element. The experimental results show 
      that the shear loading-displacement curves of the specimens can be divided into 
      elastic stage, strengthening stage, and softening stage. The increases of the 
      strength of the concrete and the layers of the transverse CFRP can both enhance 
      the shearing load carrying capacity of the specimen. With the increase of 
      concrete strength, there is no obvious change in the shape of the shear 
      stress-shear strain curves of the specimens, and the shear stress and the 
      stiffness of the curve in the elastic stage of the specimen are slightly 
      increased. The shear loading-displacement curves of the specimens are simulated 
      by using finite element software ABAQUS and it is found that the predicted 
      results agree reasonably well with the test results. Then, the whole process of 
      loading and the parameters of the main influencing factors are analyzed. Finally, 
      the calculation equation of CFRP concrete-filled steel tubular shear capacity is 
      established.
