| 摘 要： | 在结构施工过程中,结构受力体系、边界约束条件、荷载分布在不断的改变。利用大型有限元软件ANSYS的“生死单元”,可以进行结构施工过程分析。主要介绍了“生死单元”的机理,并举例分析了仅与“杀死单元”相连接的节点的约束问题,使其能较好的模拟结构施工过程。

| Abstract: | In the process of structure construction, the structural system, boundary constraint conditions and load distribution are constantly changing. Using the birth-and-death elements of the large finite element analysis software ANSYS can facilitate the construction analysis of the structures. In this paper, the principle of the birth-and-death elements is introduced. With practical examples, nodes' constraints were illustrated, which are only connected with death elements so as to make it able to simulate the structure construction course better. |
