The test research work of CFST(concrete-filled steel tubular) joints is focused on the following factors: bending moment transferred way of beam
loading mode
the influence of thickness of steel tube
and the deflection property of beam.The result shows that deformation of steel tube nearing joint increases with the increment of beam end’s moment.The deformation of steel tube also increases with the increment of initial axial compression when the moment is applied.But the influence is limited to a local zone.The axial bearing capacity of joint is not influenced basically by the above factors.
