摘    要:本文建议了一种简单的一维过渡单元。该单元可用来连接杆件与线性实体单元,用于进行结构-基础-地基系统和组合结构的分析。所选择的单元位移函数能够满足过渡单元与相邻的实体单元间的协调条件。文中典型算例说明,建议的过渡单元对于组合结构和弹性基础上结构的应力和稳定分析是十分有效的。

关 键 词:有限元  过渡单元  弹性基础

Abstract:In this paper,a simple one-dimensional transitive element is proposed. The element may be used to join bars and linear solid elements in analyzing structure-foundation-soil systems and compositive structures.The displace- ment function of the element is selected to satisfy the compatibility require- meats between the element and the adjoining solid elements.Some typical examples show that the proposed transitive element is quite effective for analyses of the stress and stability of compositive structures and structures on elastic foundations.
Keywords:finite element method  transitive element  compositive structure  elastic foundation
