Study Finite Element Analysis of Monopile Foundation based on Mechanical Mechanics and Properties of Steel Structure for Offshore Wind Turbines

Statistical data shows that monopile foundation accounts for more than 65% of all foundations for offshore wind turbines,so it is of great engineering value to perform the research on the design and analysis of the monopile foundation. By its application environments and structure features,based on a design example of monopile foundation for a offshore wind farm,the paper performs the following sequence of works including the establishment of finite element model for monopile foundation, the calculation of foundation bearing capacity and deformation, modal analysis and fatigue analysis, etc. The paper gives the related design results, which is used for reference for designers.
