摘要

摘要: 利用极限平衡理论对圆形截面钢管膨胀混凝土轴压短柱的极限承载能力进行分析,得出圆形截面钢管膨胀混凝土短柱的极限承载能力的计算式。对钢管膨胀混凝土的膨胀模式以及由于核心混凝土的膨胀引起的钢管与核心混凝土界面间的初始接触压力的大小、影响钢管膨胀混凝土短柱的极限承载能力的因素进行讨论,极限承载力计算结果与试验结果吻合较好。

Abstract: The ultimate bearing capacity of axially compressed expansive concrete-filled steel tube(CFT) short columns with circular section is analyzed using the limit analysis theory.The formula for the ultimate strength of expansive CFT short columns is proposed.Meanwhile,the expansive model of expansive CFT and the initial contact pressure between the tube and the core concrete caused by the expansion of concrete core are investigated.The factors influencing the ultimate bearing capacity of expansive CFT short columns are discussed.The calculated results obtained by the proposed formula are in good agreement with the experimental ones.
