Abstract: To calculate the static-stiffness matrix of the unbounded soil for use in a time-domain analysis of soil-structure interaction, the consistent infinitesimal finite-element cell method is developed. Its derivation is based ...

Abstract: For dynamic excitation, it is convenient to idealize homogeneous soil under a base mat by a semi‐infinite truncated cone. It is easy to analyze the cone model for vertical and horizontal translation, as well as for rocking ...

Abstract: It is quite difficult to compute rigorously the dynamic response of a footing or base mat on a soil layer resting on rigid rock. As an alternative to the rigorous approach, the semi‐finite truncated cone models appropriate ...

Abstract: In a strength‐of‐materials approach to foundation dynamics, approximate Green's functions are employed in lieu of rigorous fundamental solutions. For a vertical point load on the elastic half‐space, the form of the Green's ...

Abstract: The dynamic analysis of surface footings may be performed approximately, but quite accurately, by idealizing the soil as a truncated cone instead of an elastic half‐space. In this paper, cone models are extended to represent ...

Abstract: An isotropic plasticity model for soil is presented that introduces a number of significant modifications into an existing bounding‐surface model for clay to extend the range of application to sand, offering a simple unified ...
