摘　　要：文章对方形钢管混凝土轴压柱局部屈曲性能进行了分析,推导了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了比较,提出了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 analyzed, and the expressions of the local buckling coefficient, local buckling half-wavelengths and the local buckling stress are derived from the analysis. The calculation results are compared with the results of experiment,and more reasonable calculation formulas are put forward, which lay a foundation for the follow-up further research.
