Abstract
Monopod bucket foundations supporting offshore wind turbines have to resist high overturning moment due to water waves and wind currents acting laterally on the structure above the seabed level. Hence, the stability of the bucket foundation system is governed by the lateral load-displacement behaviour. In this study, the drained behaviour of monopod bucket foundation under monotonic eccentric lateral loads has been investigated using finite element analysis. The influence of bucket dimensions and wind turbine self-weight on the lateral load response of the foundation system was also studied. The ultimate lateral load capacity of the bucket foundation has been observed to decrease with the increase of load eccentricity, but it increases marginally with self-weight and noticeably with the foundation size. For a preliminary design of the bucket foundation, the permissible loading state is presented as a lateral load-overturning moment interaction diagram for different geometries.
