摘　　要：从双剪统一强度理论出发,推导出钢骨-钢管混凝土中核心混凝土抗压强度的计算公式,从而得出钢骨-钢管混凝土轴压短柱承载力理论计算公式,并与文献的试验结果和已有的计算公式进行比较,所得结果吻合较好,说明双剪统一强度理论对于钢骨-钢管混凝土承载力的理论计算具有很好的适用性,为钢骨-钢管混凝土的分析计算提供了又一有效的方法。New design formulae of axial compressive circular steel tube column filled with steel-reinforced concrete were presented based on the twin shear unified strength theory.Predictions from the derived formulae were compared with test results and existed formulae and satisfactory agreements were reached.It is concluded that the twin shear unified strength theory is versatile in theoretical analyses of the composite column.

关 键 词：双剪统一强度 钢骨-钢管混凝土柱 承载力
