In the analysis of the mechanical state in frame constructions using the finite element method (FEM), frame geometric models and related frame finite element formulations are most often used. As with any numerical modeling formulation or technique, the frame structure model has its strengths and weaknesses. The shortcoming appears mainly in the detailed analysis of the joints and the calculation of the mechanical state in them. Therefore, it will be compared with the analysis of welded frame joints in the construction of a terrace canopy with shell and volume numerical model.
