摘要
本文给出了求结构各层刚度中心的一种迭代计算方法。该方法便于有限元计算程序的实现，适用于各种复杂结构。根据本文建议的计算方法，我们在多、高层建筑空间有限元分析与设计软件ＳＡＴＷＥ和ＴＡＴ中，增加了计算结构各层刚度中心的功能。这项功能将有助于设计人员更好地把握设计方案。
A kind of iterative method for calculating the stiffness centers of various stories of a building structure is proposed in this paper. The suggested method is convenient for programming and can be used to any kind of complex building structures. The new feature for calculating the stiffness center of steel structure has been added in the softwares of SATWE and TAT,which may aid the designers to optimize the design scheme of building structures.
