中文摘要：
简要介绍了钢管混凝土组合柱轴心受压承载力已有的主要计算方法。在提出组合柱轴压承载力极限状态及组合柱轴压峰值应变的基础上,建立了组合柱轴压承载力计算公式。采用该文公式计算了34个组合柱试件的轴压承载力,计算值与试验值符合良好。为使轴心受压组合柱的峰值应变大于管外箍筋约束混凝土的轴压峰值应变、小于钢管混凝土的轴压峰值应变,提出了钢管混凝土截面面积在组合柱总面积中所占比例的上限值建议。
英文摘要：
A brief introduction to the available main methods of calculating the axial compressive strength of steel tube-reinforced concrete composite columns is presented.The ultimate state of axial compressive strength of composite columns and a formula for calculating the peak compressive strain of the composite column are proposed.Based on those,formulae for calculating the axial compressive strength of composite columns are developed.The axial compressive strength of 34 composite column specimens are calculated by the developed formulae,the calculated results have good agreement with the test results.In order to make the peak compressive strain of the composite column less than the peak compressive strain of the stirrup confined concrete out of the steel tube and larger than the peak compressive strain of the steel tube confined concrete,the upper limit value of the proportion of the steel tube confined the concrete area over the overall sectional area of the composite column is suggested.
