摘　　要：考虑钢材强度、混凝土强度、轴压比等参数,进行了18个钢管高性能混凝土试件的试验,分析在往复荷载作用下钢管高性能混凝土荷载-位移关系曲线的特点、构件的轴向变形和抗弯刚度退化情况,并初步探讨往复荷载作用下的钢管高性能混凝土压弯构件承载力。The flexural force-deformation behavior of eight concrete-filled steel tubular beam-columns was experimentally investigated and the results are presented in this paper.The parameters in the study are the axial load ratio and strengths of steel and concrete strength. The characteristics of load versus deformation hysteretic curve and the rule of rigidity degradation were analyzed. Methods to calculate the bearing capacity for high-performance concrete-filled steel tubular beam-columns are discussed.
