| 摘 要： | 选择合理的单元类型、材料本构关系,利用非线性有限元分析程序ABAQUS对内隔板外伸式钢管混凝土柱-钢梁节点进行了三维有限元分析,在试验研究的基础上进一步探讨了节点的受力性能和传力机理.分析结果表明,该类节点传力路径清晰,有较好的强度和刚度,满足"强节点,弱构件"的抗震设计原则;建立的三维有限元模型能够比较准确地模拟节点的实际工作状态.

| Abstract: | Choosing the appropriate element type and material constitutive model,nonlinear finite element analysis software ABAQUS is used to analyze the type of inner-through diaphragm connection which is composed by the concrete-filled square steel tubular column-steel beam.The capacity and mechanism of this type connection are discussed further based on the results of experiment.The numerical results show that the load transfer pathway is clear and the strength and stiffness are well.The aseismic principle strong c... |
