摘要: 本文分析了矩形钢管与混凝土之间的相互作用，借鉴Vion-Mise屈服准则和过–王混凝土破坏准则分别确定了钢管和混凝土的单轴纵向强度，提出矩形钢管混凝土轴压短柱的承载力计算公式。最后，用建议公式对21个试件进行承载力计算，计算结果与试验结果和规范计算结果吻合良好。
Abstract: In this paper, the interaction is analyzed between rectangular steel tube and concrete. The longitu-dinal strength of steel tube and concrete core is determined according to Vion-Mise yield criterion for steel and Guo-Wang failure criterion for concrete. The ultimate strength equations for rectan-gular concrete-filled steel tube stub column subjected to axial load are proposed. Finally, 19 spec-imens are calculated by the proposed equations and the calculated results agree with the experi-mental and normative ones very well.
