本文提出了位移法多级子结构模式分析中处理位移约束的一个新的有效方法。此 方法在单元和超级的元中，而不是在子绍构模式门施加节点位移之间的主从关系约 束，以及满足指定零位移的刚性边界条件，并作好满足指定非零位移的刚性边界条件 的准备。在任意一级子结构模式总变位向量中皆不包含指定非零位移。 水文的方法还便于在程序中自动地处理复杂结构分析中各种约束，并且节省计算 机内存和计算工作量以及僻免不必要的方程病态。本文的方法已在ＪＩＧＦＥＸ系统中 实现．
This paper presents a new and effective method for dealing with displacement constraints in multilevel substructure analysis of displacement methods. This method does not impose the master-slave relationship constraint between node and super element in the element and super element, and satisfies the rigid boundary conditions for the specified zero displacement, and satisfies the rigid boundary for the specified non-zero displacement. Preparation of conditions. None of the specified non-zero displacements are included in any of the primary sub-mode total displacement vectors. The hydrological method also facilitates the automatic handling of various constraints in complex structural analysis in the program, as well as saving computer memory and computational workload and avoiding unnecessary equation ills. The method of this paper has been implemented in the JIGFEX system.
