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?
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?
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?
Stiffness Modulus Method
Is it possible to perform an analysis according to the stiffness modulus method in RFEM or RSTAB?
Unstable Model - Troubleshooting
My model in RFEM 6 / RSTAB 9 is unstable. How can I fix it?
Exclude Lateral Torsional Buckling Check
My beam has a continuous lateral support and therefore lateral torsional buckling (LTB) is not a concern. How do I define the effective length?
Uneven Terrain
The terrain surface of my soil to be analyzed is uneven. How can I edit the geometry of my soil massif for the modeling?

Materials of National Annexes
Where can I find the materials for the corresponding National Annexes in RFEM 6 and RSTAB 9?
Strength of Weld-Affected Zone for Aluminum
How do I consider the strength of weld-affected zone for aluminum?
Analyse de déformation
Is it possible to display the deformation analysis of a surface (limit 0.5‰)?
Small Cohesion for Non-Cohesive Soils
What value can I use for cohesion in order to avoid singularities?
Stability Analysis with Incrementally Increasing Loading
Can I incrementally increase the load in RFEM 6 or RSTAB 9?
Orthotropy Direction for Layers
Why cannot I define a rotation when defining layers?
Setting Deformations to 0
How can I set the deformations from an LC/CO or a construction stage to 0?
Activating Geotechnical Analysis Add-on
I have a license for the Geotechnical Analysis add-on and it appears as available to me. However, I cannot activate it. What could be the reason?
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?
Cable and Tensile Structures
I would like to analyze cable and tensile structures. Is it possible to use RFEM or RSTAB for this?
