To study the axial compression performance of high strength concrete-filled steel tube composite columns,the test data of several concrete-filled steel tube composite columns are calibrated using the finite element software ABAQUS for numerical simulations with parametric analysis.The results show that the selected parameters can effectively simulate the axial compression performance of high strength concrete-filled steel tube composite columns.The influences of stirrup spacing,confinement index,steel ratio and concrete strength on the axial compression performance of composite column are given for the design reference.
