Resumen:

This paper presents results of a recent study concerning the optimum design for wind and seismic hazards in Mexico of wind turbines supports. A well establish optimum design procedure for estimating optimum base bending moment due to earthquake and wind hazards is outlined. This procedure is based on the minimization of the total cost due to the initial or construction cost and the cost of losses when structural failure occurs during its life. It is required a realistic description of the construction cost in terms of the intensity, as well as a complete and accurate description of the hazard given by excedance rates curves. Utilizing this optimum design model and characterization of wind and seismic hazards in Mexico through their ex-cedance rates of maximum gust wind speeds and peak ground accelerations, optimum base bending moments have been quantified and presented in contour maps for Mexico.
