摘要:
在统一强度理论的基础上,对配有纵向钢筋和箍筋的圆钢管混凝土短柱轴心受压时的受力性能进行了分析; 考虑了钢管和箍筋对混凝土的约束作用,推导出了配筋圆钢管混凝土短柱的轴压承载力计算公式; 分析了中间主应力、钢管径厚比和体积配箍率对承载力的影响。将公式的计算结果与文献试验结果进行比较,二者吻合较好。结果表明:统一强度理论对于配筋圆钢管混凝土轴压短柱的理论计算有非常好的适用性,为配筋钢管混凝土柱的分析计算提供了一定的理论依据。
Abstract:
Based on the unified strength theory,the mechanical behavior of reinforced concrete-filled circular steel tube short columns was analyzed. The calculation formulas of axial bearing capacity of the reinforced concrete-filled circular steel tube short columns were deduced with considerations of the restriction effects of steel tube and hoop bar on concrete. Parametric studies were carried out to evaluate the effects of intermediate principal stresses,diameter-thickness ratio of steel tube and the stirrup ratio on the bearing capacity. A reasonable match was reached by comparing the results calculated by the formulas with the test results by the references. The results show that the unified strength theory has a good applicability in the theoretical calculation of the reinforced concrete-filled circular steel tube short columns, which can offer theoretical reference to analyze and calculate the reinforced concrete-filled steel tube columns.
