Question
How do I determine the stiffness center of my structural system?
Question
Why do the results of members and sets of members differ in the design?
Geo-zone tool
I noticed deviations from the map of DIN EN 1998‑1 or DIN 4149 in the online service "Geo-Zone Tool: Snow Load, Wind Speed, and Seismic Load Maps". Can you tell me which map is current and thus governing?
Elastic critical moment for lateral-torsional buckling
What are the options in RFEM 5 or RSTAB 8 for determining the ideal elastic critical moment for lateral-torsional buckling for any cross-sections and systems/loads? Is it also possible to design flat steel (brackets, flat steel stringers of staircases)?
Consideration of Heat Affected Zone for Aluminum
Is it possible to consider the reduction of strength in the heat affected zone (HAZ) in the RF‑/ALUMINUM add-on module?
Question
How can I display nodal masses?
Question
How can I change the shear correction factor kcr in RF‑JOINTS Timber - Timber to Timber?
Question
I would like to design the connection of the diagonals of a truss with a steel lower flange and timber diagonals. Is this possible?
Overstrength Factors
How do I include the overstrength factor(s) Ωo in the ASCE 7 load combinations?
Question
It is not possible to design a SHAPE‑THIN cross-section due to invalid symmetry. What is the cause and how can I fix it?
Redundancy Factors
How do I include the redundancy factor(s) ρ in the ASCE 7 load combinations?
Question
Which formula is used in the RF‑/TOWER Loading add-on module to calculate the first natural frequency for the determination of the structure coefficient?
Question
I am trying to design an open, unsymmetric aluminum cross-section in RF‑/ALUMINUM and I am get the warning "Non-designable - 1022) General cross-section — Check of stability is not available". What is the reason?
Question
When performing the fire resistance design with TIMBER Pro, I get Error 10001. How can I fix the error?
Question
Is it possible to design the support pressure or the compression perpendicular to the grain in RX‑TIMBER?
Question
Is it possible to import effective lengths from RF‑STABILITY or RSBUCK in RF‑/TIMBER Pro?
Imperfection from Mode Shape
How do I create an imperfection based on a mode shape in RFEM 6?
Question
I need to define different types of lateral intermediate restrains for a single element in RF-/STEEL EC3. Is this possible?
Question
Is it possible to automatically consider the rigidity of fasteners in the RF‑/JOINTS Timber - Steel to Timber add-on module when determining internal forces?
Question
I have a question about the results of the serviceability limit state design: How is the increment of the dead load by the factor of 1.8 and the imposed load by 1.48 explained in the result combinations for the SLS design?
Question
I get an implausible result with the expression "1.#J" in the RF‑/ALUMINUM add-on module.
How can I fix this?
Question
I cannot calculate members with double rectangular cross-sections and linearly variable cross-section height in TIMBER Pro. What is the reason?
AISI Table B4.1-1 Applicability Limits
Does RFEM check the applicability limits of AISI Table B4.1‑1?
Standardized Sections for AISI Design
Which standardized sections are valid for AISI cold-formed steel design in RFEM 6?
