Abstract

A method of analysis for predicting the earthquake induced response a structure on a flexible foundation soil is presented. The foundation soil is represented by a bed of elasticplastic springs allowing both the strength of the soil and its stiffness to be incorporated in the analysis. Application of the method indicates: (1) the vertical component of the earthquake has a negligible effect on the response of the structure (2) the maximum induced overturning moment depends primarily on the strength of the soil and whether the foundation is free to lift from the soil (3) overturning of tall buildings is unlikely to occur unless the foundation soil suffers a strength loss due to the shaking.
