摘要
本文在方钢管混凝土柱压弯试验的基础上,探讨了轴压比影响柱延性的原因,并推导了试验轴压比与设计轴压比的换算关系公式。最后根据换算关系公式和试验数据,以层间弹塑性位移角作为延性控制指标,提出了方钢管混凝土框架柱的轴压比限值,以供设计参考。
This paper based on experiment of concrete filled square steel tubular columns under combined constant axial load and cyclic lateral loads, the reasons of the effect of axial compression ratio on the ductility of composite column are discussed in this paper .The conversion relation between experimental axial compression ratio and design axial compression ratio is deduced .Finally, the limited values of axial compression ratio of concrete filled square steel tubular columns are brought forward on the basis of the deduced result and experimental data.
