外文摘要：The accurate calculation and evaluation of wave loads are crucial in the design of offshore monopile foundations. To address this challenge, this study develops a fully nonlinear time-domain model based on potential flow theory to study nonlinear wave loads and the corresponding ringing effects on deformable monopile foundations. The incident potential is precomputed using a spectral wave model, while the scattered field is solved with a higher-order boundary element method. Fluid-structure interaction is modeled by mapping the pressure-induced forces onto the structural nodes, and the dynamic response is computed via a finite-element scheme and velocities are time-stepped accordingly. Validation against experimental measurements and published numerical results demonstrates the reliability and precision in forecasting wave run-up and wave loading. The analyses highlight the excitation of resonant ringing responses, particularly at triple-frequency conditions, under varying damping ratios, incident-wave steepness and frequencies. These results offer new insights into wave-structure interaction mechanisms. They enhance the accuracy and practicality of offshore engineering design methodologies, particularly by highlighting the critical role of hydroelastic effects in the design and life-cycle assessment of monopile foundations.
