ANALYSIS OF GRAVITY OFFSHORE STRUCTURE FOUNDATIONS.

This paper shows that the interaction of an offshore structure with its soil foundation when subjected to complicated wave loading paths can be analyzed in a rigorous manner by taking into account the real three-dimensional, nonlinear, anisotropic, elastoplastic, path-dependent, stress-strain-strength properties of the material. A brief summary of a soil model's basic principles is presented, along with an outline of its main features and capabilities. The model's extreme versatility and accuracy are demonstrated by applying it to represent the behavior of a particular soil under both monotonic and cyclic loading conditions.
