Abstract

Highlights
• The rotation of tripod foundation system in dense sand due to cyclic loading was analyzed by performing 3D FE analyses.
• The HS small and the UBC3D-PLM soil models were employed to analyze the moment response of offshore foundations.
• The procedures were validated against a database of well-documented centrifuge tests.
• The resulting decreasing trend in accumulated rotation (the so called “self-healing’’ mechanism) was discussed.
