Pri analizi mehanskega stanja v linijskih konstrukcijah po metodi končnih elementov (MKE) največkrat uporabljamo linijske geometrijske modele in z njimi povezane formulacije linijskih končnih elementov. Tako kot vsaka formulacija ali tehnika numeričnega modeliranja ima tudi linijski model konstrukcije svoje prednosti in slabosti. Pomanjkljivost se tako pojavi predvsem pri detajlni analizi spojev in izračunu mehanskega stanja v njih. Zato se ga bo primerjalo z analizo profilnih zvarnih spojev v konstrukciji terasnega nadstreška z lupinskim in volumskim numeričnim modelom. 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. |
