Abstract in Portuguese
Este trabalho é uma contribuição para o estudo de modelos de representação da não linearidade física de estruturas de concreto. Nele estudou-se o Modelo de Campo Distorcido de Tensões, ou Disturbed Stress Field Model - DSFM, através da implementação no programa MATLAB®. O programa desenvolvido implementa também o Modified Compression Field Theory - MCFT, que é a base para o DSFM. Neste trabalho também foi utilizado o programa VecTor2 desenvolvido na Universidade de Toronto. Neste documento é apresentada a base teórica das formulações estudadas, o programa desenvolvido é descrito brevemente e são apresentados resultados obtidos.

Abstract in English
This research consists on the study of nonlinear behavioral models for reinforced concrete. The main focus of this study is the Disturbed Stress Field Model - DSFM. In order to study this model, it was implemented in the MATLAB® platform. The basis for the DSFM is the Modified Compression Field Theory MCFT, this model was also implemented using MATLAB®. The VecTor2 program developed at the University of Toronto was also used. This document presents the formulation for these analytical models, a description of the developed tools and the results obtained through them.
