Two‐Parameter Layer Model for Analysis of Slab on Elastic Foundation

Abstract

A foundation medium is divided into a number of horizontal layers, Each layer is idealized by a system of multiple one‐dimensional vertical columns interconnected by shear springs. The model is defined by two parameters, which are found to be uniquely defined by the material properties of the layer only. Formulations are proposed to obtain the model parameters from the elastic constants of the layer medium. Using the model, the responses of the elastic slab resting on an elastic foundation are formulated. Good agreement is found between the responses computed by the present formulation and a finite element method.
