（安徽建筑大学土木工程学院，合肥 230022）［摘要］介绍了计算圆钢管混凝土短柱轴压承载力的8种国内外规程，依据各规程计算公式，对21根圆钢管混凝土短柱试件的轴压承载力进行理论计算，并将理论计算结果与试验结果进行对比分析。结果表明：虽然各规程在计算公式的表达上各不相同，但所考虑的因素基本一致，其计算结果大多偏于保守。并对基于统一理论的我国规程和基于叠加理论的国外规程的计算值与试验值进行了对比，《钢管混凝土结构技术规程》（DBJ 13-51—2003）偏差程度最小，计算结果相对较为准确。［关键词］圆钢管混凝土; 短柱; 轴心受压; 理论计算; 对比分析中图分类号：TU398+.9 文献标识码：A 文章编号：1002-848X(2015)05-0059-04Comparative analysis of axial compression bearing capacity of circular concrete filled steel tube short columns calculated by codes at home and abroadHe Xiping, Liu Shen, Zhang Dawei（College of Civil Engineering, Anhui Jianzhu University, Hefei 230022, China）Abstract: Eight kinds of domestic and foreign codes of circular concrete filled steel tube short columns for calculatiug axial compression bearing capacity were introduced. According to the calculation formulas of each code, theoretical calculation of axial compression bearing capacity of 21 circular concrete filled steel tube short columns was given, and the theory calculated results were compared with the experimental results. The results show that although there are differences in form among these calculation formulas of the codes, but the factors considered in these codes have little difference and most of the calculated results are conservative. The calculation values of our country codes based on the unified theory and abroad codes based on superposition theory were compared with the experimental values. The deviation degree of Technical specification for concrete-filled steel tubular structures(DBJ 13-51—2003) is the smallest and the calculation result derived by this code is relatively accurate.Keywords: circular concrete filled steel tube; short column; axial compression; theoretical calculation; comparative analysis*国家科技支撑计划课题资助（2011BAJ03B04），安徽省教育厅高等教育振兴计划课题资助（2013zdjy121）。作者简介：何夕平，硕士，教授，注册造价工程师，注册监理工程师，Email：1047080558@qq.com。参考文献［1］钟善桐.钢管混凝土结构［M］.哈尔滨:黑龙江科学技术出版社,2002.［2］何夕平，张大伟，许前程，等.国内外规程对方钢管混凝土短柱轴压承载力计算对比分析［J］.青岛理工大学学报，2013,34（1）:33-38.［3］ACI 318-99 Building code requirements for structural concrete and commentary［S］.
