The results of the study demonstrate that under the condition of the same slendness ratio , the stability factor of axially compressed medium long concrete filled steel tube column has no relation with peak stress of the core concrete , instead , the factor will depend on peak strain of the concrete 研究结果表明,在长细比相同的情况下,钢管混凝土轴压中长柱的稳定系数与核心混凝土的峰值应力无关,而取决于核心混凝土的峰值应变。
This paper conducts a study of the influence of core concrete performance upon the stability factor of axially compressed medium long concrete - filled steel tube column on the basis of comparison of the axial compression test results of long column made up of common concrete filled steel tube and medium long column made up of lightweight aggregate concrete - filled steel tube , and in accordance with analysis of the constitutive relation curves between both the common and lightweight aggregate concrete 摘要通过对钢管普通混凝土长柱和钢管轻集料混凝土中长柱的轴压试验结果的比较,结合对普通混凝土和轻集料混凝土的本构关系曲线的分析,研究了核心混凝土性能对钢管混凝土轴压中长柱稳定系数的影响。
