Title: NUMERIC MODELING OF THE DAMAGE IN REINFORCED CONCRETE STRUCTURES.
Author(s): Jaime Retama Velasco, A. Gustavo Ayala Milián y J. Jesús Gutiérrez Trejo.
Appears on pages(s): 39-48
Keywords: Reinforced concrete, finite element, damage mechanics, embedded discontinuities, inelastic analysis.
Abstract:This paper presents a variational formulation and numerical implementation of a problem of interest in the study of the mechanical behavior of reinforced concrete elements based on a two dimensional displacement approximation of the finite element method in which the steel reinforcement is introduced using bar elements located within the concrete finite elements. To simulate the strain hardening effect of the reinforcement steel an elastic—plastic constitutive model is used. The damage undergone by the concrete material is modeled by an embedded discontinuity approach. The developed formulation is implemented in a finite element computer program and applied to a structural element subjected to tension; considering that the failure process initiates in mode—I, to continue in a mixed mode on its evolution to collapse. This example considers a cross section with and without two different reinforcements.
