摘　　要： 通过双钢管高强混凝土柱、单钢管高强混凝土柱、钢管芯钢筋高强混凝土柱以及型钢芯钢筋高强混凝土4种组合柱轴压静载试验,得出了各种组合柱的荷载-位移曲线,分析了组合柱的工作及破坏机理,比较了组合柱的轴压承载力并对其轴压性能作了试验对比分析,对相关研究和设计具有一定的参考价值. According to experiments of static axial compressive bearing capacity of four kind of composite columns,the double high-strength concrete filled steel tube column,high-strength concrete filled steel tube column,high-strength concrete column with steel tube core and that with shaped steel cord,load-displacement curves of composite columns under axial loads are obtained. Mechanisms of operating and fracture of composite columns are analyzed, the ultimate axial compressive bearing capacity of composite columns are contrasted, and experiments of axial compressive performance are studied, which can be use for reference of related studies and design.
