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?
Cross-Section Warping
How can I display the cross-section warping?
Results of Punching | Concrete design in RFEM 6
Where can I find the graphical results of punching shear in the concrete design? Especially the distribution of shear forces at the critical perimeter or the punching loads.
Stiffness Modulus Method
Is it possible to perform an analysis according to the stiffness modulus method in RFEM or RSTAB?
Warping Spring and Warping Restraint
How can I define a warping spring or a warping restraint?
Unstable Model - Troubleshooting
My model in RFEM 6 / RSTAB 9 is unstable. How can I fix it?

Why are the members not valid for the Concrete Design add-on?
Why are the members not valid for the Concrete Design add-on?
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?
Modal Analysis
How can I display mode shapes in RFEM 6 and RSTAB 9?
Normalization of Mode Shape
Where can I adjust the normalization of a mode shape in RFEM 6 / RSTAB 9?
Warping Release
How do I set a release for warping?

Is it possible to design single-layer reinforced surfaces with RFEM 6?
Not Covered Reinforcement on Members | Concrete Design in RFEM 6 and RSTAB 9
Although all the member design checks have been fulfilled, I get the "Not Covered Reinforcement" result. What is the reason?
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?
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?
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?
Nominal Reinforcement Bar Size
Can I define a different bar size in the RFEM 6 Concrete Design add-on other than the default bar sizes available in the drop-down?
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?
Punching
I would like to perform punching design of a floor slab. I have selected nodes for the design, but they are marked as invalid. Where did I make a mistake?
Creep and Shrinkage of Concrete
Where can I activate creep or shrinkage for concrete design?
