Resumo: A new method for fracture analysis of reinforced concrete structures in proposed. The concrete is modeled as an assembly of distinct elements made by dividing the concrete virtually. These elements are connected by distributed springs in both normal and tangential directions. The reinforcement bars are modeled as continuos springs connecting elements together. Local failure of concrete is modeled by failure stress. In element formulation and the computer code were developed and the accuracy of the method were verified by comparing many experimental results. In these experiments, the results showed good agreement in determining the failure load-deflection relations the prediction od crack initiation, crack location and crack propagation. The formulation used to develop this method are simple and efficient in modeling the mechanical behavior of RC structures (AU)
