Abstract:	This work presents an Euclidian Minimum Norm criterion for Limit Plastic Synthesis of floors, in reinforced concrete buildings, as an altemative to Limit Plastic Synthesis of slabs by Linear Programming. Both the techniques discretize the continuum using a triangular rigid-plastic finite element of the Plastic Limit Analisys, in accordance with the Yield Line Theory, for case of slabs with usual boundary conditions. It is shown that the Limit Plastic Synthesis algorithm using the Euclidian Minimum Norm criterion is the similar to the Stiffiiess Method algorithm, allowing the simulation of the behavior of the material of both combined floor models; that is: (a) Plastic slabs with elastic grid, and, (b) Plastic slabs with plastic grid. An automatic linear-elastic computation of reinforced concrete, under Service load, was carried out and compared with the plastic calculation for the determination the ortotropy index and verification of the floor system slabs in Service. To formulate the algorithm to solve the elastic slabs model, the DKT triangular finite element for bending of thin plates was implemented. The examples presented ilustrate the validity and efficiency of the elastic slab analisys models and plastic synthesis for floor Systems, in reinforced concrete, formulated here. As a complementary criterion for the Euclidian Minimum Norm, the fundamental theorems of plastic theory for structures, limit plastic analisys and yield line theory, in the plastic analisys of slabs over rigid bases, are outlined.
