Análise numérica de vigas de concreto armado reforçadas com compósito contendo fibras de juta através do método dos elementos finitos

Abstract

The objective of this labour is present a numerical model able to investigate more realist the behavior of reinforced concrete beams strengthened in bending, considering the linearity of the materials In this context this work presents a numerical approach to fracture based on the Finite Element Method. This numeric approach fracture is the method called cohesive interfaces. Their description is given and its implementation in the analysis for the detected failure mode. Two beams were simulated the first one being a reference beam without the application of the reinforcement and the second a beam reinforced composites jute fiber base in the tensioned region of the structural element. To verify the accuracy of the numerical model developed if we compare the numerical results with experimental results. These comparisons we obtained pretty good approximations between the numerical and experimental results.
