The application of the post-tensioned concrete in slabs has been diffused more and more, through the development of new constructive techniques and need of practical solutions in the area of the construction.Many studies were and they are being accomplished with the intention of knowing the behavior of post-tensioned slabs, in way to iclude all the advantages, with safety, of their constructive possibilities. This work consists of the comparison of two analysis methods, Method of the Finite Elements and Method of the Equivalent Porches, applied in two models of flat plane slabs different, presenting numeric results. The first part of this work tries to syntheticize the design fundamentals of the posttensioned concrete floors, without great theoretical deepnings, serving as orientation summarized, but objective, on the subject. Already second part presents numericals result and the comparison between them.
