Abstract:
Eighteen self-compacting high-performance concrete-filled steel tubular columns were tested under axial compressive loads. The main parameters varied in the tests were mixture ratios of self-compacting concrete and loading modes. Based on the relationship between stress and strain of self-compacting concrete-filled steel tubular and concrete, a practical calculation method for theoretical analysis was applied by using axial strength bearing capacity of steel tubular columns. The finite element program ANSYS was applied to the analysis of axial compressive column load-strain relationship. It shows that the testvalues are higher than the theoretical values and are in good agreement with the finite element analysis. The test results have some practical references for relevant engineering application.
