多层地基上框架结构计算的半解析法

Semi-analytical Method for Computing Framem on Layered Foundations

本文提出了一种分析多层地基上平面框架结构的有效方法.该法分别用有限单元法和解析法求解结构底部的单位位移和多层地基的表面沉陷系数,用混合法求解结构与地基相互作用的基底反力,最后采用叠加原理求出结构的位移和内力.

In this a paper, an effective method is presented to analyse the twodimensional frame on a layered foundation. Taking advantage of.finite element method and analytical solution to find the unit displacement of the structure and the surface settlement of the layered foundation, the mixed method is used to compute the pressure between the structure and its foundation. The displacements and interior forces are determined by use of the superposition theory.
