离心螺旋筋管混凝土中长柱小偏心受压承载力研究

Study on Load Carrying Capacity of Spiral Reinforced Concerete Tube Column with Medium-slenderness

根据对实验结果的分析，以螺旋筋体积配筋率μ、偏心距比ｅ／ｒ＿（ｈｅ）、长细比λ为控制变量，对螺旋筋管混凝土中长柱的承载能力进行了试验研究，提出了方便简单的承载力计算公式，讨论了横向钢筋体积配筋率对界限偏心率、界限长细比的影响。

This paper focuses on the experimental research of spiral reiaforced concrete tube column. Load carrying capacity and influeaces of voluma steel ratio on the limit eccentricity and slenderness ratio are studied . On the basis of analys is of test results, simple practical formulae are given by the authors.
