Resumen

El objetivo de este trabajo es simular el agrietamiento en estructuras de concreto mediante dos enfoques: enfoque de grieta distribuida y enfoque de grieta discreta. Se analizaron dos casos de estudio: una viga con refuerzo ordinario y un extremo recortado de viga modelados mediante elementos finitos tridimensionales. Primeramente, se utilizó el enfoque de grieta distribuida para localizar la zona de agrietamiento en ambos casos de estudio. Posteriormente, para simular el ancho de la grieta se utilizó el enfoque de grieta discreta aplicando un modelo de zona cohesiva haciendo uso de una función que representa la abertura de la grieta. Los resultados obtenidos se validaron con resultados experimentales. Esta investigación proporciona la eficiencia y la aplicación de los dos enfoques para estimar la aparición y el ancho de grieta para estructuras de concreto reforzado.
