Why Dlubal Software?
The deformations of the FE nodes are always the first result of an FE calculation. Based on these deformations and the stiffness of the elements, it is possible to calculate strains, internal forces, and stresses.
For more detailed investigations of shear/hole bearing connections or their immediate environment, the definition of the non-linear contact problem plays an important role. This article uses a solid model to search for comparable and simplified surface models.
With RF-/FRAME-JOINT Pro, it is possible to design frame joints according to DIN 18800 or Eurocode 3. When considering non-standardized joints or taking a closer look at the joint and its behavior, it is recommended to use a modeling as surface model. The following article will show how such a model is created in principle.
For the reduction of loads generated in RF‑MOVE Surfaces, it is possible to consider influence surfaces of a selected point. The influence surfaces are determined by RF‑INFLUENCE. This procedure is useful in cases where only unfavorable acting loads should be considered. Depending on the unfavorable action, you should select the positive or negative direction.
