中文摘要	用试验与数值计算方法研究了普通方钢管混凝土柱的轴压承载能力。设计了2种复合截面方钢管混凝土短柱,与普通方钢管混凝土短柱做了对比轴压试验。试验结果表明,在受压柱变形的过程中,加劲肋有效地抵抗了管壁的屈曲,加肋复合方钢管混凝土柱的轴压承载力有明显提高。用数值方法对加肋复合方钢管混凝土柱的轴力应变全过程进行了计算。计算结果和试验结果吻合较好。提出了轴压承载力的简化计算方法。加劲肋是提高方钢管混凝土柱承载力的有效途径。; The enhancement of the axial bearing capacity of ordinary square concrete-filled steel tubes was investigated experimentally and numerically.Two kinds of composite-sectioned tubes were designed with their axial bearing capacities compared to that of common concrete-filled steel tubes.The results show that the reinforced ribs effectively prevent the tube plates from buckling during the deformation process under compression,so that the axial bearing capacity of the composite-sectioned tubes with ribs is much higher.The numerical results of the whole axial load-strain process for these tubes agree well with the experimental results.A simplified computing method is given to estimate the bearing capacity of the reinforced tubes.The design of these ribbed steel tubes is recommended for axial bearing elements.; 国家教育振兴计划项目(JC2002005)
