| 摘 要： | 用三维20结点固体单元,对TT节点在支管端部承受轴向压力作用下所能承受的极限载荷进行了数值模拟.将结构有限元网格划分为不同区域,每个区域的网格独立产生,通过合并形成整个结构的有限元网格.使用ABAQUS软件分析了TT节点在支管端部承受轴向载荷的变形及与外部载荷之间的关系,得到了不同参数影响下的TT节点极限载荷.

| Abstract: | Numerical modelling is carried out for the analysis of the ultimate loading capacity of tubular TT-joints subjected to axial compression at the end of the brace.In the numerical modelling,20-node solid elements are used to model the entire structure.Sub-zone mesh generation method is used in the mesh generation procedure.The entire structure is divided into several zones and the mesh of each zone is produced separately.Thereafter,the mesh of the entire structure is obtained by merging the mesh of all the zones.The general software package ABAQUS is used to analyze the relation between the external loads and displacement for TT-joints subjected to axial compression at the end of the brace.The effects of different parameters on the ultimate loading capacity of TT-joints have been investigated. |
