| dc.title | Development of a macroelement based design model for offshore suction bucket foundation in clay | en_US |
| dcterms.abstract | In this master's thesis, the behaviour of a suction bucket foundation in clay for an offshore wind turbine under combined monotonic load is studied. Firstly, the failure process and failure envelope of a suction bucket foundation under combined monotonic load are numerically investigated via finite element analysis using the modified Cam-clay and hardening soil constitutive models, respectively. Then the hardening soil constitutive model is selected to conduct finite element numerical simulations for suction bucket foundations in clay under complex monotonic loads, based on which an analytical function is presented to describe the 3D failure surface. On this basis, a macro-element model of a suction bucket foundation for both monotonic and cyclic loading conditions is proposed. Compared with experimental results, the effectiveness and efficiency of this method are verified. | en_US |
