【摘要】 深入研究方中空夹层钢管混凝土构件的力学性能是该类结构的基础.文章结合已有文献中方中空夹层钢管混凝土柱的轴压试验,采用ANSYS软件分析钢管混凝土轴压构件,混凝土采用考虑钢管约束效应的本构关系,钢材采用双线形随动强化模型,采用ANSYS(APDL)编制命令流,并结合数值方法对方中空夹层钢管混凝土轴压柱的荷载-变形关系的分析.显示AN-SYS计算结果和试验结果以及数值计算吻合较好.更多还原

【Abstract】 The analysis and research for the concrete-filled double skin steel tubular with square section is the basic of the type structural.The text combines the history data of axial compression experiment about the concrete-filled double skin steel tubular column with square section.In this dissertation,ansys command streams are edited to APDL language.The constitutive equations of the core concrete considering the restraint effect of steel tube is built,and the constitutive equations of the steel is bilinear(BKIN) model.And make use of the number procedure,the finite element analysis result is accord with the experiment result and number procedure.更多还原
