摘　　要：为研究小直径灌浆薄壁钢管短柱轴压承载力,制作了6个试件进行轴压试验,对其轴压承载力进行了研究。结果表明,小直径灌浆薄壁钢管短柱承载力较高,具有良好的延性,可采用现行规范公式进行计算。用有限元模拟软件对其进行数值模拟,模拟数值与试验数值结果基本吻合。To research the axial pressure bearing capacity of short filling steel pipe column with small diameter and thin wall,six testing samples were made for axial pressure bearing capacity test.The test result showed that short filling steel pipe column with small diameter and thin wall has relatively high bearing capacity,and favorable ductibility,and that formula in current specifications could be used for calculation.Finite element software was used for numerical simulation and the simulation value is basically same with the test result.
