摘　　要：通过8根钢骨-钢管混凝土组合柱的轴压承载力试验,研究了组合柱的工作机理、延性和极限承载力.结果表明,由于钢管、钢骨和混凝土的协同工作,可有效地提高柱子的承载力,延缓或抑制混凝土中剪切斜裂缝的开展,提高柱子的延性.另外,利用有限元软件ANSYS对组合柱轴压试验的全过程进行了数值模拟,得出的荷载-位移曲线与试验曲线吻合较好.The working mechanisms, ductility and ultimate bearing capacity were studied through bearing capoacity experimentation of 8 axially loaded composite columns. Results show that the load-bearing capacity and ductility of the composite column are improved, and the propagation of crack in concrete is mitigated effectively as concrete and steel work together. Composite columns under axial loading were amalyzed by using finite elment software ANSYS and their loading-displacement curves were obtained, which agree well with experimental curves.
