Materials of National Annexes
Where can I find the materials for the corresponding National Annexes in RFEM 6 and RSTAB 9?
Modal Analysis
How can I display mode shapes in RFEM 6 and RSTAB 9?
Response Spectrum Analysis
How can I perform an earthquake analysis in RFEM 6 and RSTAB 9?
Modal Analysis - Minimum Initial Strain
Why do the results in a modal analysis differ between the initial prestress and the surface load?
Neglecting Masses in RFEM 6 / RSTAB 9
How can I neglect masses in my modal analysis in RFEM 6 / RSTAB 9?
Normalization of Mode Shape
Where can I adjust the normalization of a mode shape in RFEM 6 / RSTAB 9?
Column Failure Modal Analysis
How can I analyze the failure of an object, such as a column, in my modal analysis?
Analyse de déformation
Is it possible to display the deformation analysis of a surface (limit 0.5‰)?
Export of Response Spectrum
Can I export a response spectrum from RFEM 6 and use it in RFEM 5, for example?
Unstable Model - Troubleshooting
My model in RFEM 6 / RSTAB 9 is unstable. How can I fix it?
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?
Construction Stages - Modifying Properties
Is it possible to change the properties of members or surfaces, such as their location, in the individual construction stages?
Cross-Section Warping
How can I display the cross-section warping?
Deactivating 7th Degree of Freedom by Member
How can I deactivate the 7th degree of freedom for only certain members or cross-sections?
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?
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?
Warping Spring and Warping Restraint
How can I define a warping spring or a warping restraint?
Warping Release
How do I set a release for warping?
Implausible Results – Torsional Warping
My results of the calculation with Torsional Warping are implausible. What could be the reason?
Case-Related Design with Different Load Situations
How can I carry out case-related design for different load situations?
Strength of Weld-Affected Zone for Aluminum
How do I consider the strength of weld-affected zone for aluminum?
Creating Response Spectrum ASCE 7-22
How can I create a response spectrum according to ASCE 7‑22?
Surface Type Error
I received an error message “Surface of incompatible type... (Surface in upper plane of building story must be of ‘Load transfer’ type)” when running the calculation. What is the reason?
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?
Instability
My model is unstable. What could be the reason?
Instability when Using Building Model with "Rigid Diaphragm"
I have a 3D model and try to split it up into "walls" and "surfaces" with the Building Model and to calculate them separately. However, my structural system becomes unstable then. What can be the reason?
Stability Analysis with Incrementally Increasing Loading
Can I incrementally increase the load in RFEM 6 or RSTAB 9?
