摘要
利用数值分析方法对高强钢管混凝土核心短柱 (L/D <4)在轴心受压时的荷载 变形关系曲线进行了全过程分析。用以往试验结果进行验证 ,吻合良好。并分析了钢管套箍指标 ,钢管强度和混凝土强度对轴压承载力的影响。最后提出了高强混凝土核心短柱轴心受压强度承载力的简化计算公式。
In this paper, a numerical method is applied for the all course analysis of complete curves of load deformation and behaviors of short core column with high strength concrete filled steel tube subjected to axial compression The results of theoretical analysis are proved to be fitting with those of the former test And the effect of main parameters on bearing capacity of axially compressed are studied Finally,the simplified calculating formula of strength of core column with HSCFST is suggested
