摘　　要：本文采用全过程非线性分析方法,编制了不等肢异形柱延性性能非线性分析程序,程序分析结果与试验结果的分析表明,二者吻合较好。应用该程序对223根不等肢十形异形柱和25根等肢十形异形柱进行了计算分析,研究了荷载角、轴压比、箍筋间距、截面肢长等因素对不等肢十形异形柱截面延性性能的影响,得到了其延性变化规律,并提出了不等肢十形异形柱的轴压比限值。275 sets of inequiaxial ＋-shaped columns and 25 sets of equiaxial ＋-shaped columns are calculated in this paper with the method of a full-range nonlinear analysis; many relevant factors including angles loading, axial force ration, spacing of lateral reinforcement and change of section for the ductility of the inequiaxial ＋-shaped columns are analyzed and its ductility performance is summarized.

关 键 词：不等肢十形异形柱 延性 曲率延性比 位移延性比 轴压比限值
