钢管轻骨料混凝土中长柱的极限承载力分析

The ultimate bearing capacity analysis of long column in steel pipe lightweight aggregate concrete

按照弹性模量理论推导出钢管轻骨料混凝土中长柱的稳定系数,建立了钢管轻骨料混凝土中长柱的极限承载力公式。结果表明:通过b值的改变,计算得出的承载力值也随之发生变化,并和文献中的实验数据进行了比较,吻合良好。

The long column stability coefficient of steel pipe lightweight aggregate concrete was deduced according to elastic ration theory, and the ultimate bearing capacity formula of long column in steel pipe lightweight aggregate concrete was built. The results indicated that the calculated bearing capacity changed with b value alternation, which was in good agreement with experimental data in references.
