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。 This article suggests a simple one-dimensional transition unit. The unit can be used to connect rods and linear solid elements for analysis of structural-foundation-foundation systems and composite structures. The selected element displacement function can satisfy the coordination condition between the transition unit and the adjacent solid element. A typical example in the paper shows that the proposed transition unit is very effective for the stress and stability analysis of the combined structure and the elastic foundation.
