This work presents a method to design membrane concrete elements with orthogonal mesh of reinforcement which are subjected to compression stress. A literature review was carried of and it shows the evolution of membrane elements research, pointing the design analytic methods proposed. These methods, in general, define a way to quantify the reinforcement necessary to support the tension stress and verify if the compression in concrete respects the strength limit. In case which the compression in membrane is excessive, it is possible use reinforcements subject to compression. However, there is no much information in literature about how design reinforcement for these cases. Thus, this paper presents a procedure with this objective which it use the model based on Baumann’s criteria as basis. In this paper, it are used as limits of strength those recommended by CEB (1990), however, it is proposed a model which this limit vary according to tension deformation which occurs perpendicular to compression. This model of strength is based on concepts proposed by Vecchio e Collins (1986).
