The study of slender structures in mechanical or civil/industrial constructions represents a continuous challenge from the view point of the risk factors identifying and offering sustainable solutions and methods to extend their life span. One of the most common and dangerous sources for the lifetime limitation of this type of structure is the buckling. The use of numerical algorithms in the applications for analyzing the structures, algorithms based on the finite element method, is a frequent solution in approaching the problem. Today, there are various software applications that have as their starting point the classic approach to the problem according to the Strength of Materials. The purpose of this article is to compare the classical approach with the output of running the working environments/platforms to establish the obtained solution convergence, highlighting the dispersion degree as well. The analyzed subject is the double joint section. Regardless the used software, the high degree of complexity of the problem requires a two steps algorithm: a buckling analysis in the linear domain followed by a nonlinear analysis. In addition, compared to other similar approached of the phenomenon, the use of the finite element with full options regarding the structure discretization (meshing) will be considered.
