Abstract

Abstract

It is important to estimate the influence of layered soil in soil-structure interaction analysis.Although a great number of investigations have been carried out on this subject,there are very few practical methods that do not require complex calculations.A simple and practical method for estimating the impedance functions of a block foundation resting on layered soil is proposed.In this method,waves propagating in the soil are traced using the conception of the cone model.
