Evaluation of sand p–y curves by predicting both monopile lateral response and OWT natural frequency

open access: yesStudia Geotechnica et Mechanica, 2022
Extending the use of the p–y curves included in the regulation codes API and DNV to design large-diameter monopiles supporting offshore wind turbines (OWTs) was unsuccessful as it resulted in an inaccurate estimation of the monopile behavior.
