First Steps with RFEM
Description
Pay particular attention to connection points of members and surfaces when you deal with mixed systems because not all internal forces can always be transferred without difficulty at the coupling location.

Manual adjustment of the buckling curve according to EN 1993-1-1
The RF-/STEEL EC3 add-on module automatically transfers the buckling line to be used for the flexural buckling analysis for a cross-section from the cross-section properties. In particular for general cross -sections, but also for special cases, the assignment of the buckling line can be adjusted manually in the module input.
Material Model Orthotropic Masonry 2D
The material model Orthotropic Masonry 2D is an elastoplastic model that additionally allows softening of the material, which can be different in the local x- and y-direction of a surface. The material model is suitable for (unreinforced) masonry walls with in-plane loads.
- When creating a material, there are no nonlinear material models available for surfaces or solids. Why?
- How can I connect surfaces to other surfaces or members in a hinged/semi-rigid way?
- The calculation of my model results in unrealistically high stresses at many locations. What is the reason?
- Can I use surface releases to separate two overlapping surfaces?
- Why do I get high differences when designing a longitudinally stiffened buckling panel compared to the German and Austrian National Annexes?
- How can I perform the stability analysis for an edgewise supported flat steel, for example 100/5, in RF-/STEEL EC3? Although the cross-section is rotated by 90 ° in RFEM/RSTAB, it is displayed lying flat in RF-/STEEL EC3.
- How can I create a curved or curved section?
- How are the signs to be interpreted for the release results of the line release and line hinges?
- How is the rotational stiffness of a buckling stiffener determined in FE-BUCKLING?
- How are hot -dip galvanized components considered for fire protection in the Steel EC 3 add -on module?
