摘　　要：为了解空心率对圆中空夹层钢管自密实混凝土短柱力学性能的影响,对9根试件进行了轴压试验。试验结果表明:在一定范围内,随着空心率的增加,短柱的承载力呈非线性降低;空心率对短柱的纵向位移影响不明显。In order to understand the influence of hollow ratio on the mechanical properties of self-compacting concrete-filled double skin steel tube stub column, 9 specimens were tested for axial compression.The experimental results show that the bearing capacity of the short columns decreases nonlinearly with the increase of the hollow ratio, and the hollow ratio has no Obvious effect on the longitudinal displacement of the stub columns.

关 键 词：圆中空夹层钢管 自密实混凝土 空心率 轴压性能
