Este estudio analiza el comportamiento de torres de telecomunicaciones atirantadas bajo la acción del viento, estructuras caracterizadas por su alta esbeltez y flexibilidad. La metodología consistió en un análisis estático basado en la norma NBR 6123 y un análisis dinámico utilizando la formulación de Monte Carlo para simular la componente fluctuante del viento. En la modelación estructural, se emplearon elementos finitos de cables y celosías con comportamiento lineal elástico, comparando dos modelos matemáticos (lineal y no lineal) para el pretensado de los cables. El equilibrio estático se obtuvo mediante el algoritmo Quasi-Newton. Los resultados demuestran que la consideración conjunta de las acciones estáticas y dinámicas es indispensable para la determinación precisa de los esfuerzos axiales máximos en los componentes de la torre.
