中文摘要	该文对12个圆锥形中空钢管混凝土叠合短柱进行了轴压试验,探讨了锥度、截面直径及是否内置钢管对圆锥形中空钢管混凝土叠合短柱轴压力学性能的影响,建议了圆锥形中空钢管混凝土叠合短柱轴压承载力计算式。结果表明:锥度、截面直径及是否内置钢管对圆锥形中空钢管混凝土叠合短柱轴压性能影响显著;建议的极限承载力计算式计算结果与试验结果总体上吻合较好,可用来预测圆锥形中空钢管混凝土叠合短柱的截面抗压强度。; A total of 12 circular tapered hollow sreel tube reinforced concrete stub columns subjected to axial compression were tested. The main parameters were the tapered angle, the diameter of a crossing section and with or without embedding a hollow steel tube. The influences of different parameters on the compressive mechanical properties of these specimens are discussed. Based on this, a simplified formula is put forward to calculate stub column bearing capacity. The test results show that the influence of the three parameters on the compressive specimens are very obvious, and the calculated results show a good agreement with the experimental results, and the formula can reasonably evaluate the ultimate bearing capacity of circular tapered hollow steel tubes reinforced concrete stub columns.
