Języki publikacji
Abstrakty
W artykule przedstawiono analizę porównawczą przemieszczeń i naprężeń obliczonych przy użyciu programów opartych na metodzie elementów skończonych: ADINA oraz Autodesk ROBOT Structural Analysis. Do obliczeń numerycznych przyjęto jednostronnie utwierdzoną belkę stalową o skrzynkowym przekroju poprzecznym (kształtownik zamknięty prostokątny wg PN-EN 10210-2:2000) z zaokrąglonymi krawędziami zewnętrznymi oraz wewnętrznymi. Obliczenia zostały wykonane w przestrzeni trójwymiarowej (3D), a otrzymane wyniki omówione w podsumowaniu.
This paper through the comparative analysis of displacement and stress results broaches the subject of computer aided design software for building structures. In the analysis there were used commonly used programs like ADINA and Autodesk ROBOT Structural Analysis, which are based on finite element method. In both programs one end of cantilever beam was modeled as a steel box with rounded edges. Dimensions of the beam were 140x80x5 mm. Loads acting on the beam were: dead load, concentrated moment acting in longitudinal cutting plane and concentrated force acting in oblique direction to the cross-section cutting plane. Calculations by above-mentioned programs were done in three-dimensional space (3D). Received results showed differences, which took place by using those two programs and next in this paper causes of those differences were discussed. Selected computation model, which is box profile with rounded external and internal edges, allowed to indicate limitations of the programs. In the essential part of this paper dedicated to computer aided design an example and computation models were shown as figures. Received results were put into tables, which allows to compare differences in obtained values. In sum-up obtained results of stress and displacement were discussed. Moreover, there were discussed limitations in programs encountered at modeling, finite element method nets types and their influence on results using FEM.
