This work deals with the development of a computational code that realizes the dimensioning of structures of automatically reinforced concrete, be it of beams, rectangular section and section T, submitted to the efforts of flexion, shear and torsion or also of massive slabs and ribbed to the flexion , Making the necessary checks to the shear. The code also includes the calculation of bending reinforcement of slabs in balance. At the end of the calculation, either beams or slabs, it presents a detailed suggestion of the calculated reinforcement, informing the user of the diameters of the reinforcements used and horizontal and vertical spacing between steel bars, always respecting the standard code of NBR 6118/2014. The calculation process adopted is iterative due to the very nature of the equation of the dimensioning problem. The tests bring a comparison of the results obtained by the iterative method of the program with the manual dimensioning with the adoption of an armature gauge. Results of steel areas are also presented when the concrete class used and the variation of the angles of the connecting rods and stirrups in relation to the shear stress, which prove results found in the literature, are presented.
