Resumo (PT): The use of finite-element packages by practitioners as a design tool for reinforced concrete struc-tures has increased considerably in the last few decades. All structural codes of practice recognise the as-sumption of linear elastic behavior as a design stage. However. the problem remains of calculating the required reinforcement in plates and shells. The amount of reinforcement is determined locally. i.e.. for each sampling point from the equilibrium between applied and internal forces. The formulation of the method includes biaxial behavior of concrete and different lever arms for all the internal forces. Ideal plastic behaviour is assumed for both materials. A reference is made to the absence of universally accepted solutions for the design of those structures and therefore, scarcity of provisions in the structural concrete codes. To uppraise the validiity of the method, a comparison is made with experimental tests on slab and shell elements. Additional numerical results for practical structures are also given.
