The contribution of foundation damping to offshore wind turbines (OWTs) is not well known, though researchers have back-calculated foundation damping from “rotor-stop” tests after estimating aerodynamic, hydrodynamic, and structural damping with numerical models. Because design guidelines do...

Considering nonlinear soil–pile interaction, seismic fragility analysis of offshore wind turbine was performed. Interface between ground soils and piles were modeled as nonlinear spring elements. Ground excitation time histories were applied to spring boundaries. Two methods of applying ground...

Understanding the response of pile foundations to seismic loads is a necessary prerequisite to properly analyze and/or design them. This objective presents the civil engineering student and teacher with a complex problem, which typically challenges and strains the traditional didactic...
