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, numerical simulations of the wind loads effects are first performed using FAST. Then, nonlinear time-history analyses of the tower structures are carried out using OpenSEES in order to evaluate the dynamic response in terms of the base moment. Finally, the probabilistic assessment of the peak response under multi-hazard is evaluated for different seismic and wind load intensities by means of Monte Carlo simulations.

Abstract
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, numerical simulations of the wind loads effects are first performed using FAST. Then, nonlinear time-history analyses of the tower structures are carried out using OpenSEES in order to evaluate the dynamic response in terms of the base moment. Finally, the probabilistic assessment of the peak response under multi-hazard is evaluated for different seismic and wind load intensities by means of Monte Carlo simulations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
