框架-筏基-地基相互作用的有限元分析

上部结构-基础-地基三者是一个受力整体系统,它们之间的相互作用和协调工作的问题一直是土木工程中非常重要的课题之一.常规的设计方法是将结构每个部分分隔开来然后分别进行计算.没有考虑整体结构彼此之间变形协调的因素,这与实际情况有很大的差异.本文借助ANSYS12.0有限元软件建立整体结构的有限元模型来分析各部分之间在受力过程中的相互作用,揭示了考虑相互作用对结构内力影响的规律,为实际工程结构设计方案的安全和经济提供重要的依据.

Framework-Raft-Foundation Finite Element Analysis of the Interaction

The upper structure-foundation-is a force as a whole system foundation,the interaction between them and coor dination problem have been one of the important subjects in the civil engineering. The conventional method is to structure off each section and then calculated respectively. Does not take into account the overall structure of the deformation coordination between each other,which have a great difference with the actual situation. In this paper,with the aid of ANSYS12. 0 finite element software to establish the overall structure of the finite element model to analyze in force between the parts in the process of interaction,reveals the considering interaction on the influence law of internal force of structure,design optimization for the practical engineering structure security and the economy to provide important basis.
