In the present study an idea of combination of fracture mechanics and Limit State Analysis is presented. The model of the “plastic hinges” is made by using theory of fracture mechanics. Analysis of a simple RC (reinforced concrete) structure by means of fracture mechanics is performed by taking into account crack development. Reinforcement plastification and nonlinear behavior of concrete are considered in the numerical model. Comparisons with a simple Limit State Analysis plastic hinge model are made. The numerical analysis is made by using ANSYS software product. This research is part of a project aimed at determining the maximum bending moment in a beam subjected to bending with the methods of fracture mechanics and the definition of a simplified formula specifying the one obtained by the Limit State Analysis.
