摘　　要：在合理选择单元类型、材料的本构关系、破坏准则以及裂缝处理的基础上,利用非线性有限元分析程序AN-SYS,对节点区柱钢管不全贯通式钢管混凝土柱-梁节点的受力机理进行三维非线性有限元分析,进一步研究该节点的裂缝形态和受力性能等.分析结果表明,有限元模型计算结果与已有试验结果吻合较好.Based on the appropriate type of the element, material constitutive model, failure cracking and crushing, nonlinear FEA software ANSYS is used to analyse the nonlinear finite ing mechanism of the concrete filled steel tubular column-beam joint zone. The crack form and mechanical properties of the joint are studied between the experimental and analytical results. criterion and model of elements on the work-with the column tube discontinuous in joint The calculation results show good agreement
