| 摘 要： | 上部结构、基础与地基土为一整体系统,在地震作用下考虑系统的共同作用是结构精确分析的基础.本文以ANSYS有限元软件为工具,进行了框架结构、基础及地基的动力时程分析.通过比较,考虑共同作用和非共同工作系统的动力响应,分析了结构动力特性、结构的侧移、底层柱的内力和基底反力分布图,得出了一些有价值的结论,对工程设计有一定的参考意义.

| Abstract: | Superstructure, foundation and soil is a whole system, the consideration of interaction of system is the basis to analyze earthquake response of structure accurately.Aimed by the finite element software ANSYS, this paper carries out a dynamical and time-history analysis of a frame structure. Comparing the dynamical response under interaction with non-interaction of the system, it is analyzed for the dynamical characteristic, the lateral displacement, the bottom column's internal force and the distributive curve of the foundation reaction. Some conclusions are made, which are valuable for engineering design. |
