| 摘 要： | 本文在钢骨-钢管混凝土组合柱压弯试验的基础上,讨论了轴压比对组合柱延性影响的原因、试验轴压比与设计轴压比的换算关系以及组合柱轴压比限值问题.根据试验结果和分析可知,对钢骨-钢管混凝土组合柱,设计时可不必限制轴压比,这可以满足组合柱延性的要求.

| Abstract: | Based on the experiment of pressure and bending loaded circular steel tube columns filled with steel-reinforced concrete, the essay discusses the reasons of the effect of axial load ratio on the ductility of composite column, the conversion relation between experiment axial load ratio and design axial load ratio and the axial load ratio limits of composite column. According to the experimental result and analysis, the axial load ratio of circular steel tube columns filled with steel- reinforced concrete is not limited in design ,which can meet the requirement of the ductility of composite column. |
