The most used design methods for steel column bases present hypotheses to the stress distribution on their connection components. The goal of this work was to analyze steel column bases through a finite element computational program in order to obtain more accurately the behavior of their components and through the results of this analysis to assess the design usual methods. The study include H profile columns with base plates without shear legs. In the numerical analysis werediscussed the bases axially loaded by a compression load with or without a bending moment. To the situation that act a bending moment it has been created models using either hooked anchor bolts and thread rods with an end welded nut embedded in the concrete. It was observed in this work the influence of the thickness of a base plate in thebehavior of the components of a steel column base (column, base plate, anchor bolts and concrete block) and in the stress distribution of these components. It was still verified that the theorical results which were found through the usual design methods approximate from the numerical analysis results to specific values of the thickness of the base plate.
