| 摘 要： | 采用双剪统一强度理论,考虑了箍筋和内圆钢管对核心混凝土的双层约束作用,对配有圆钢管的钢骨混凝土轴心受压柱的受力性能进行了理论分析。在厚壁圆筒统一强度理论的基础上,推导出了柱的受压承载力公式,并对影响因素进行了分析。将该公式的计算结果与文献资料的试验结果进行了比较,结果吻合较好,表明统一强度理论对配有圆钢管的钢骨混凝土的理论分析有很好的适用性。该结果为配有圆钢管的钢骨混凝土柱承载力的分析计算提供了一定的理论依据。

| Abstract: | Based on the twin shear unified strength theory,with consideration of the double restriction effect of hoop bar and steel tube on core concrete,the calculation formula of bearing capacity of the SRC columns with steel circle pipe is deduced and the influence factors are analyzed.The obtained results well agree with the test results of reference.The results indicate that unified strength theory has good applicability and the solution has an important practical value. |
