基础设计中上部结构刚度贡献解决方案探讨

Research on Function of Superstructure Stiffness in Design of Foundations

地基、基础、上部结构是相互作用、共同工作的统一体系中的三个部分。在目前上部结构与下部结构分别设计计算的状况下,本文利用位移法及子结构的概念,解决了上部结构荷载及刚度的传递,使上下部共同作用计算定量化,可以应用于任意复杂结构的计算。

Soil, foundation and superstructure are three parts of a structural system.They interact each other and work together. At the present time, superstructure and foundation are designed separately.This paper uses displacement method and substructure concept to solve a transfer of the superstructure loads and stiffness. So the interaction of superstructure and foundation can be calculate quantitatively. The method can be used to calculated any complicated buildings foundation.
