Método de Analogía de la Fuerza, Análisis no lineal, bilinealResumen
El Método de Analogía de la Fuerza, FAM, (Force Analogy Method) es una herramienta innovadora que permite realizar el análisis estático y dinámico de una estructura considerando la no linealidad del material. El FAM puede usarse considerando historias de tiempo aplicadas en la base o en la masa de cualquier sistema; el FAM es una herramienta que permite hacer análisis con precisión y rapidez, con una gran eficiencia computacional. La metodología puede emplearse en sistemas con control pasivo y activo, además de considerar modelos de comportamiento a flexión, carga axial, cortante y efectos no lineales debido a la geometría del elemento. En este artículo, se presenta en detalle el FAM, proporcionando sus bases teóricas y una guía para su implantación práctica. Se muestran ejemplos prácticos que abarcan desde sistemas de un grado de libertad hasta estructuras de varios niveles, considerando no linealidad debida a la flexión utilizando el modelo bilineal. Los resultados se comparan con los obtenidos por los métodos tradicionales de análisis, obteniéndose resultados similares.
