✦ Synopsis

A 2-D analysis of the soil-structure interaction for a jack-up platform is presented. The special features of the analysis are." --soil behaviour modelling under cyclic loading uses elasto-plastic equations with a multiple yieM surface and kinematical hardening." --the study is not executed on a single isolated spud-can, but on a more comprehensive structural model including the soil and a 2-D reduction of a complete jack-up structure," --the loading history consists of some one-hundred cycles representing two storm sea states separated by small set-up cycles.

The main result is that the bottom fixity displayed during the first storm is not significantly degraded during the second storm, even though irrecoverable displacements and rotations occur.
