摘　　要：对方形钢管混凝土钢管壁局部屈曲行为进行弹性分析,推导钢管壁发生局部屈曲时的屈曲系数、屈曲半波长及临界屈曲应力表达式,并与局部屈曲试验研究成果进行比较,提出更为合理的计算公式,为后续的进一步研究打下基础。The local buckling of the steel plates in thin-walled concrete-filled steel box columns is analysed. The local buckling coefficient,local buckling half-wavelenghs and the formula of the critical buckling stress derived from the analysis are compared with the results of the experiments, and the more reasonable calculation formula is also proposed, which provides the foundation for the follow-up further research.
