Different Stresses in Static Analysis and Stress-Strain Analysis
Why are the stresses of the structural analysis different from those calculated with the Stress-Strain Analysis add-on?
Stability Analysis of Structural Components with Asymmetric Cross-Section
Is it possible to use the general method according to EN 1993‑1‑1, 6.3.4 to design structural components with an asymmetric cross-section in the Steel Design add-on for RFEM 6 or RSTAB 9?
Structure Below Ground Level
Why does the integration/support of my building in the ground below the ground level not work?
Design Cases
Can I use design cases in RFEM 6 in the same way as in RFEM 5?

Programs for Steel Structures
Which programs and add-ons are suitable for the structural analysis and design of steel structures?
CSA S16 Class 4 Sections
Can I design members with Class 4 sections according to CSA S16 in the Steel Design add-on?
Setting Deformations to 0
How can I set the deformations from an LC/CO or a construction stage to 0?
Standardized Sections for AISI Design
Which standardized sections are valid for AISI cold-formed steel design in RFEM 6?
Custom Sections for AISI Design
Can I design user-defined (parametric) sections according to AISI S100 or CSA S136?
AISI Table B4.1-1 Applicability Limits
Does RFEM check the applicability limits of AISI Table B4.1‑1?
Geotechnical Analysis and Load Cases
I want to consider the soil-structure interaction using one of the nonlinear soil material models. Why is it not reasonable to calculate the individual load cases with this model?
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?
Overstrength Factors
How do I include the overstrength factor(s) Ωo in the ASCE 7 load combinations?
Redundancy Factors
How do I include the redundancy factor(s) ρ in the ASCE 7 load combinations?
Implausible Results – Torsional Warping
My results of the calculation with Torsional Warping are implausible. What could be the reason?
Small Cohesion for Non-Cohesive Soils
What value can I use for cohesion in order to avoid singularities?
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?
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?
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?
Effective Lengths for Steel Stability Design
How do I define effective lengths when designing steel members in RFEM 6?
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?
Unsymmetrical Cross-Section (UPE)
I am having trouble with the design of a steel structure. For a singly symmetric cross-section (UPE), the program cannot perform the stability analysis. It reports that the Equivalent Member Method 6.3.3 is not applicable for an unsymmetrical cross-section. Is it possible to design such cross-sections in the program?
Adapted Method (Enable Double Bending)
I cannot analyze a UPN cross-section subjected to double bending in the program. Is it possible to do this in the program?
Design of Member Sets
I have activated Steel Design in my model and defined design types for the members. Why can I not design the superordinate member set?
Analyse de déformation
Is it possible to display the deformation analysis of a surface (limit 0.5‰)?
