Instability
My model is unstable. What could be the reason?
Question
What are the stiffness reduction factors k33 and k88 in the Multilayer Surfaces Add-on?
Instability
My model is unstable. What could be the reason?
Member Design Supports for Deflection Checks
How do I define a member as a cantilever and not as supported at both ends for serviceability or deflection design?
Supports and Loads for Calculation with Warping Torsion
At which point on a cross-section are the supports and loads assumed for the calculation with warping torsion?
Stress Ratio
The limit stress is activated, but my stress ratio is “non-designable” in the Stress-Strain Analysis add-on. What could be the reason?
Cross-Section Warping
How can I display the cross-section warping?
Warping Spring and Warping Restraint
How can I define a warping spring or a warping restraint?

Materials of National Annexes
Where can I find the materials for the corresponding National Annexes in RFEM 6 and RSTAB 9?
Analyse de déformation
Is it possible to display the deformation analysis of a surface (limit 0.5‰)?
Deactivating 7th Degree of Freedom by Member
How can I deactivate the 7th degree of freedom for only certain members or cross-sections?
Implausible Results – Torsional Warping
My results of the calculation with Torsional Warping are implausible. What could be the reason?
Equivalent Round Section Dimension
How is the dimension for an equivalent round section calculated in the Timber Design add-on?
Orthotropy Direction for Layers
Why cannot I define a rotation when defining layers?
Stability Analysis with Incrementally Increasing Loading
Can I incrementally increase the load in RFEM 6 or RSTAB 9?
Setting of I-Beam Flange Support for Design in Structure Stability Add-on
In the Steel Design add-on, I have set the boundary conditions in such a way that the I-beam flange is restrained against the horizontal displacement. I then calculated the critical load factors using the Structure Stability add-on, but with no effect on the critical load factor value. What is the reason for this?
