STOCHASTIC DYNAMIC RESPONSE ANALYSIS OF OFFSHORE WIND TURBINES CONSIDERING SOIL-PILE INTERACTION

摘要

Soil-pile interaction may have obvious effects on the response and reliability of the offshore wind turbines.In the present paper,the integrated model of offshore wind turbines is extended to include the soil-pile interaction,and is validated by comparing the results with the commercial software.Further,the responses with and without considering the soil-pile interaction is studied.Based on the investigations,the probability density evolution method is employed to evaluate the first-passage reliability of the offshore wind turbines involving soil-pile interaction.
