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?
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?
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?
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?
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?
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?
Effective Lengths for Steel Stability Design
How do I define effective lengths when designing steel members in RFEM 6?
Implausible Results – Torsional Warping
My results of the calculation with Torsional Warping are implausible. What could be the reason?
Redundancy Factors
How do I include the redundancy factor(s) ρ in the ASCE 7 load combinations?
Overstrength Factors
How do I include the overstrength factor(s) Ωo in the ASCE 7 load combinations?
Orthotropy Direction for Layers
Why cannot I define a rotation when defining layers?
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?
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?
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?
Equivalent Round Section Dimension
How is the dimension for an equivalent round section calculated in the Timber Design add-on?
CSA S16 Class 4 Sections
Can I design members with Class 4 sections according to CSA S16 in the Steel Design add-on?
