摘　　要：本文对钢管高强混凝土柱进行低周反复水平荷载作用的试验,得到了不同轴压比情况下的滞回曲线及骨架曲线,讨论了钢管高强混凝土柱压弯承载力计算公式的适用性。结果表明,钢管高强混凝土柱具有很高的承载力及良好的抗震性能。Tests of high strength concrete filled steel tube (CFST) columns under low-reversed cyclic horizontal loads are carried out to study the looping curves and skeleton curves under different axial compression ratios. Meanwhile the effectiveness of the formulation of compression-bending capacity of high strength CFST columns is studied and analyzed. The tests prove that high strength CFST columns can provide great capacity and good seismic behaviors.
