| 摘 要： | 在统一强度理论的基础上,对圆钢管约束型钢混凝土短柱的轴心受力性能进行理论分析;采用厚壁圆筒统一强度理论计算钢管对核心型钢混凝土的约束应力,推导出圆钢管约束型钢混凝土短柱的轴压承载力公式;并对影响因素进行分析。将公式的计算结果与文献试验结果进行比较,结果吻合较好,说明统一强度理论对于圆钢管约束型钢混凝土轴压短柱的理论计算有很好的适用性,可为圆钢管约束型钢混凝土柱的分析计算提供一定的理论依据。

| Abstract: | Based on the unified strength theory,the mechanical behavior of circular tubed steel reinforced concrete(CTSRC) short columns was analyzed.The calculation formula of bearing capacity of the CTSRC short columns under axial compression was deduced with consideration of the restriction effect of steel tube on SRC by using the unified strength theory solution of thickness cylinder.Parametric studies were carried out to evaluate the effects of influence factors on the bearing capacity of the column.A reasonable match was reached by comparing the results calculated by the formulas with the test results.It was concluded that the unified strength theory was versatile in theoretical analyses of the CTSRC short columns. |
