| 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. |
