框架结构-刚度在共同作用中的效应

EFFECTION OF THE INTERACTION BETWEEN FRAME TEXTURE AND STIFFNESS

本文运用有限元法，探讨了上部结构刚度变化对结构内力和位移的影响。通过算例分析，揭示出共同作用的实质，并得出对工程实际有益的结论。为计及土的非线性特性，地基采用Ｅ－μ模型。

In this paper,the finite element method is used to study the effect of the superstructure stiffness when it is changed to the inner force and displacement.A typical sample is analyzed to disclose the essence of the interaction and some useful and interesting results to practical design are obtained In order to considering the non linearly E μ model is selected.
