Abstract

The finite element model of the round-ended concrete-filled steel tube compression-bending shear member was established by ABAQUS finite element software, and the accuracy of the model was verified. The working mechanism of the round-end concrete-filled steel tube compression-bending shear member was analyzed by using the model, including the lateral bearing capacity, axial force development, and interaction force of the component. The effects of shear-span ratio, axial compression ratio, long and short axes, concrete strength, and steel yield strength on the bearing capacity of the compression-bending shear component were discussed. The results show that the long and short axis loading significantly affect the mechanical performance of the round-end concrete-filled steel tube compression-bending shear components, and the long axis loading components show higher bearing capacity and better ductility, and the ultimate bearing capacity is reduced by 49% on average when the short axis and long axes are loaded. When the shear-span ratio is between 1.0 and 3.0, the compression-bending shear failure of the long-axis loaded member is obvious. The bearing capacity and ductility of the component gradually decrease with the increase of the axial compression ratio, but when the axial compression ratio does not exceed 0.4, the change has little effect on the ultimate bearing capacity.
