中文摘要：
利用有限元软件ABAQUS建模，并对圆中空夹层钢管混凝土轴心受压时的荷载-变形全过程关系曲线进行计算，计算结果与试验结果符合良好。同时，对轴压时荷载-变形全过程中内外钢管和混凝土所承担的荷载及其相互作用力进行分析，并对空心率、名义含钢率和材料强度等因素对相互作用力的影响进行分析。
英文摘要：
Load-deformation relationship curves of concrete filled double-skin steel tubes （CFDST） subjected to axial compression are analyzed by finite element analysis （using ABAQUS software ）. The outer steel tubes and the inner steel tubes are circular hollow sections （CHS）. The predicted load versus deformation relationship curves are in good agreement with those of tests. Based on the finite element analysis, loads carried by the inner steel tubes, outer steel tubes and concrete respectively during the loading process, as well as interactions between them are analyzed. Finally, influences of hollow section ratio, nominal steel ratio and strength of the materials on the interactions between steel tubes and concrete are investigated.
