Amortiguamiento en estructuras de acero mediante tratamiento a cortante
Abstract
En este trabajo se evaluó la efectividad de los materiales viscoelásticos para disipar energía en edificios de acero por medio de simulaciones numéricas con elementos finitos usando el programa ABAQUS. El material viscoelástico se aplicó entre dos capas elásticas para crear un tratamiento a cortante. Las curvas de variación del factor de pérdida con respecto al parámetro de cortante para los tres primeros modos de vibración son construidas para la condición de apoyo impuesta por un edificio de corte. Se estudian diferentes combinaciones de espesores y se demuestra que aumentar el espesor de la capa del viscoelástica no implica necesariamente un aumento en la disipación de energía. Los resultados encontrados mostraron que el tratamiento a cortante no es efectivo cuando se aplica en las columnas de edificios de acero.
