Keywords: soil-structure interaction analysis, shallow foundation, cone models, time domain, rocking, layered half-space.

Summary

As an alternative to the rigorous approaches, it is convenient to idealize soil by the semi-finite truncated cone models representing the infinite nature of supporting soil. The one-dimensional wave equation for cones can be solved directly in the time domain. The formulation directly in the time domain has been obtained for the translational degree of freedom for a shallow foundation on a layered half-space, while the wave pattern in the time domain is not studied for a rocking degree of freedom. The concept of echoes converts the response of the footing on a homogenous half-space to that of the footing on layered soil. It is also applicable when the layered system is excited by rocking moments. The purpose of this paper is to provide equations for the direct analysis of the interaction of soil-structure for the rocking degrees of freedom in the time domain using the theory of cones. The results obtained exclusively in the time domain, are in good agreement with the frequency domain analysis results.
