摘　　要：采用非线性全过程数值仿真算法确定不等肢T型、L型、十字型柱截面曲率延性比。再根据异形柱框架结构受地震作用时应具有的柱截面曲率延性水准确定不等肢T形、L形、十字形柱轴压比限值,为不等肢异形柱设计提供了必须的依据。The curvature ductility ratio of cross-section for inequal-leg T-shaped, L-shaped and cross-shaped columns are computed by the numerical method. On the basis of the calculation results, the ultimute axial compression ratio for the inequal-leg T-shaped, L-shaped and cross-shaped columns is presented.

关 键 词：不等肢异形柱 轴压比限值 曲率延性比
