| Abstract: | In this paper, a numerical method is applied for the all course analysis of complete curves of load deformation and behaviors of short core column with high strength concrete filled steel tube subjected to axial compression The results of theoretical analysis are proved to be fitting with those of the former test And the effect of main parameters on bearing capacity of axially compressed are studied Finally,the simplified calculating formula of strength of core column with HSCFST is suggested |
