In this section, the DAFs based on contact pressure, soil stress and foundation settlement are examined considering four different wind speed conditions, i.e., v¯hub = 8 m/s, 11 m/s, 15 m/s and 20 m/s, which cover an extensive portion of the observed range of wind speeds in mountainous areas. The acceleration and velocity at the ground surface that are caused by dynamic wind loads are also analyzed. In the following analyses, the dimensions are normalized with respect to the external base radius of

Wind loads are random variables, which induce significantly greater responses in structures than do static loads. We develop a finite-infinite element model of a 2 MW wind turbine using ABAQUS and then verify it with in situ data. The adopted dynamic constitutive model of the soil is based on the Davidenkov skeleton curve. The results demonstrate that the dynamic amplification factors (DAFs) strongly depend on wind speed and spatial position. Considerable values of the DAFs, ground acceleration, and ground velocity are observed, suggesting that...
