Consolidation problems associated with foundations for off‐shore structures are described and analysed using the finite element method. The structure itself and the soft underlying soil are modelled by finite elements with different constitutive relationships for each. Interfacial behaviour between the two is simulated by six‐noded elements, with a hyperbolic stress–strain relationship. Having modelled the soil–structure system behaviour during the consolidation stage, a soil–structure interaction analysis is then carried out for both shallow and deep foundations. Other important factors, such as the redistribution of stresses in the structure itself which have resulted from differential settlements, will also be investigated.
