Comparison and Numerical Modeling of Seismic Structures and Single Pile Foundations in Wind Turbines

The world today has an approach to clean and renewable energy and is moving towards the elimination of fossil fuels. Wind energy has created a competitive environment for other types of fuels, which reduces costs in renewable energy generation, shifts and prefers this energy to other types. Finally, the expansion of the industry is a technological breakthrough in achieving future goals in energy and the environment. The design of the turbines and the design of these turbines have been controversial issues in the industry and there have been various applications for use in these offshore structures, the most common of which are single piles and mono piles. Suitable,substrates for the construction of wind turbinesunder various environmental factors such aswind and waves; meanwhile many of these seas are in seismic areas affected by accidental earthquake loading. In this paper, nonlinear modeling of two single pile foundation and Payson Suction foundation models and its finite element analysis by Abacus software have attempted to study the bed and foundation response under environmental loads of wind, wave and earthquake, finally a step has taken to improve the design and optimization of wind turbines at sea
