方形钢管混凝土短柱轴压承载力计算方法对比

摘要

以方形钢管混凝土短柱的轴压承载力为研究对象，总结了现有的几种计算理论及计算公式，通过各公式的计算结果与试验结果的对比表明，基于叠加原理的EC4（2004）公式较其他规范公式在计算方形钢管混凝土轴压强度时有更好的适用性。%Taking the axial compression bearing capacity of square steel tube concrete short columns as the research object,this paper summa-rized the existing centralized calculation theory and calculation formula,through the comparison showed the calculation results and experimental results of each formula,based on superposition principle EC4(2004)formula had better applicability in calculation of square steel tube concrete short columns axial compression with other specification formula.
