Creating Response Spectrum ASCE 7-22
How can I create a response spectrum according to ASCE 7‑22?
Line Hinge of Slab-Wall Connection
I would like to connect my masonry wall to a reinforced concrete slab. What is the best way to create a line hinge?
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?
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?
Warping Release
How do I set a release for warping?
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?
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?
Export of Response Spectrum
Can I export a response spectrum from RFEM 6 and use it in RFEM 5, for example?
Case-Related Design with Different Load Situations
How can I carry out case-related design for different load situations?
Construction Stages - Modifying Properties
Is it possible to change the properties of members or surfaces, such as their location, in the individual construction stages?
Implausible Results – Torsional Warping
My results of the calculation with Torsional Warping are implausible. What could be the reason?
Deactivating 7th Degree of Freedom by Member
How can I deactivate the 7th degree of freedom for only certain members or cross-sections?
Small Cohesion for Non-Cohesive Soils
What value can I use for cohesion in order to avoid singularities?
Neglecting Masses in RFEM 6 / RSTAB 9
How can I neglect masses in my modal analysis in RFEM 6 / 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?
