In the preparation of structural projects, one of the most important steps is the calculation of the slabs, these being the first structures calculated and, from them, the dimensioning of all other structural elements occurs. In order to design such projects, structural calculation programs have been gaining more space in the market for structural engineering, but manual calculation is still the most widespread model, although it is not very suitable when it comes to agility. Analyzing this, the present work presents a study related to the comparative analysis between two distinct methods for the design of massive slabs, in order to obtain the most reliable way to calculate these elements. The comparison was made through the manual calculation and through the computational software Eberick, where were verified the values of bending moments and the steel area of the slabs of a residence. The verification showed that the results found through the software, in general, resulted in larger values for the bending moments compared to those calculated manually. There was also discrepancy in the calculation of the areas of steel, but the comparative showed, for most of the slabs, very similar. With the analysis of the variations, it was concluded that the methods were efficient in the calculation of the longitudinal reinforcement of the slabs, however the most recommended method for the design of the massive slabs is the computational software, since it better simulates the real behavior of the structures.
