Abstract
Based on rational constitutive model of steel and concrete,load-deformation relationship curves of concrete-filled square steel tube reinforced concrete columns subjected to axial compression were calculated by the finite element method to investigate the behavior of composite column.Based on the research conclusion mentioned above,behavior analysis of concrete-filled square steel tube reinforced concrete columns subjected to axial compression was carried out,including axial compression failure mode,axial compression load vs.deformation curves,stress development rule and interaction between concrete and steel tube.These research methods and results in this paper may be referred for correlative research.
