Probabilistic Assessment of the peak response of horizontal axis wind turbines to wind and seismic actions

This study presents some results on the peak response assessment of a 5-MW, land-based Horizontal Axis Wind Turbines (HAWTs) support structure, under the combined effects of wind and seismic loads. Using a decoupled approach, simulations of the wind and seismic loads effects are performed separately applying a specific model to define the aerodynamic damping and then joined. Then, the probabilistic assessment of the multi-hazard peak response parameters was developed from Monte Carlo simulations of the tower structure subjected to different wind and seismic loads scenarios.
