title = "Effect of stiffness degradation of clay in the dynamic response of monopile-supported offshore wind turbines",
abstract = "Stiffness degradation studies for monopile-supported offshore wind turbines (OWTs) are usually limited to the geotechnical domain, largely ignoring the dynamic loads from the wind and the waves. This paper makes use of a time-domain approach, coupling aerodynamic and hydrodynamic loads, to investigate the influence of stiffness degradation in clay on the response of a monopile-supported OWT in a water depth of 20 m. p-y curves are used to represent the soil–structure interaction (SSI) in the lateral direction and a suitable degradation method is applied to consider the effects of cyclic loading. It is observed that the influence of stiffness degradation wanes with increasing number of load cycles. OWT{\textquoteright}s being highly dynamic structures; the debilitating effects of stiffness degradation cannot be entirely discounted.",
