| 摘 要： | 基于平截面假设和大小偏压界限理论,采用截面高斯积分法,对L形柱当肢长厚比小于2.5时不同荷载角、不同肢长厚比情况下的轴压比限值进行数值分析,得出以下主要结论:不同荷载角作用时轴压比限值不同;肢长厚比越大,轴压比限值越小。设计L形柱时应满足最不利荷载角时的轴压比限值要求,且肢长厚比不宜过大。

| Abstract: | Based on plane assumption and large and small eccentric compression limitation,the ultimate axial compression ratio of reinforced concrete L-shaped columns is computed when the ratio of length to thickness of section is less than 2.5,by the section Gauss numerical integration method.The following main conclusions can be drawn: the ultimate axial compression ratio of L-shaped columns is affected by different loading angles.The ultimate axial compression ratio reduces with the increasing of the ratio of length to thickness of sections.The ultimate axial compression ratio at the worst loading angle should be satisfied,and the ratio of length to thickness of sections should not be too large in practice design. |
