In this report a macro-element model for bucket foundations is formulated and validated against small-scale experimental results. The topics investigated are the response of the foundation under general monotonic loading and the long-term accumulated displacements under cyclic loading. The macro-model for shallow foundations proposed by Nova and Montrasio (1991) is modified to comply with the response of skirted foundations for offshore wind turbines under general loading. On the base of di Prisco et al. (2003a), the constitutive relationship is modified to account for cyclic loading. The validation of the macro-model against the physical experiments shows promising results.
