| 摘 要： | 根据大小偏心受压界限破坏原理 ,分析和讨论了异形柱轴压比限值问题 ,得出了异形柱轴压比限值随截面含钢特征值变化的规律。指出对于T形和L形柱按《混凝土结构设计规范》或其他规程规定的轴压比限值进行异形柱抗震设计有时是不安全的 ;根据计算分析结果 ,提出了异形柱轴压比限值的建议值。

| Abstract: | The ultimate axial compression ratio for the specially-shaped columns is computed by the numerical method.The following conclusions can be drawn:For T-,L-shaped columns,it is not safe to design according to the ultimate axial compression ratio of the present Design Code For Concrete Structures or the other criterions.Some suggestions about the ultimate axial compression ratio for specially-shaped columns are given. |
