Circular Footings on Viscoelastic Foundations.

Abstract

The interaction of a vibrating circular footing with its foundation was investigated. To account for the energy dissipation when propagating through the supporting ground, the foundation was assumed to behave as a viscoelastic medium. The response of the footing was found to depend upon its own mass and vibration frequencies and the foundation material properties. But, for the convenience of engineering applications, the response was expressed in terms of a scaled amplitude ratio and the static deflection of the footing. Curves for the scaled amplitude ratio were presented and their possible applications to design problems were illustrated. (Author)
