This study presents a sparse-memory-encoding framework that incorporates advanced algorithms to address these limitations in large-scale simulations.

Existing failure mechanism-based soil-pile interaction model, i.e. <em>p-y + M-θ</em> model, is specifically developed for monopiles under lateral wind loading in non-seismic areas. To date, there is still a lack of failure mechanism-based <em>p-y + M-θ</em> model considering the combined actions of wind loading and seismic loading that is transmitted upward from the pile toe. This study aims to (a) reveal the failure mechanisms of monopile with varying rigidity under combined wind and seismic loading, and (b) to develop a dynamic <em>p-y + M-θ</em> model in accordance with these mechanisms. The first objective is achieved through a series of 3D finite element analyses well-calibrated by centrifuge model tests, which reveal a new mechanism (i.e., translation-shear failure) introduced by seismic loading, as an addition to the three-zone failure mechanism typically observed for a pile solely under wind loading. A dynamic <em>p-y + M-θ</em> model is then developed in light of these failure mechanisms associated with both wind and seismic loadings, with hysteretic damping and frequency-dependent radiation damping specifically introduced to enable dynamic analyses. The new model is validated against numerical analyses on piles subjected to seismic and wind loadings. Compared to the authors’ original <em>p-y + M-θ</em> model, the newly proposed model can better describe dynamic soil-pile interaction in seismically active areas, as it poses two additional simulation capabilities: (a) amplified lateral pile displacement due to the translation-shear failure caused by the seismic movement of whole pile embedment; (b) suppressed structural response due to the radiation damping aroused from the high-frequency seismic movement.</div></div>","PeriodicalId":55217,"journal":{"name":"Computers and Geotechnics","volume":"180 ","pages":"Article 107074"},"PeriodicalIF":5.3,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143171742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the damage characteristics of rock mass, the model will degrade the tensile strength, cohesion, dilation angle, normal and shear stiffness parameters of the joint based on the fracture energy value when the joint is in tension and shear yield state, and make the model eventually degenerate into a pure friction Mohr-Coulomb model under zero cohesion.

Comparison with the results from finite element method confirms the reliability of the semi-analytical model and demonstrates the significance of incorporating the geometric nonlinearity.

The numerical results show that neglecting geometric nonlinearity tends to diminish the influences of modulus ratio, while high-frequency impulse loading leads to amplified rebound and re-impact phenomena.
