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
For the settlement calculation in the RF‑SOILIN add-on module, the specific weight gamma and gamma,sat are required for the soil. What do I need the value gamma,sat for, and how is it assumed in the calculation?
AISC 360-16 Shear Plane in Thread Option
Can I exclude bolt threads from the shear planes according to AISC 360-16 in the Steel Joints Add-on?
Overstrength Factors
How do I include the overstrength factor(s) Ωo in the ASCE 7 load combinations?
Splice Connection
How do I create a splice connection in the Steel Joints add-on?
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
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?
Opening RWIND in RFEM 6 or RSTAB 9
How can I open RWIND using the load wizard in RFEM and RSTAB?
Question
Is it possible to import effective lengths from RF‑STABILITY or RSBUCK in RF‑/TIMBER Pro?
Question
I need to define different types of lateral intermediate restrains for a single element in RF-/STEEL EC3. Is this possible?
Question
What happens if I activate the "Soil failure" function in RF‑SOILIN?
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 have used the RF‑/DYNAM Pro add-on module to generate the governing result combinations of seismic loads. What is the next procedure to perform the design of the individual structural components?
Question
Red values are displayed in the intermediate results of RF‑SOILIN. Why?
Question
I have performed a buckling analysis in RF‑ALUMINUM. Where can I find the parameters used for the design in the add-on module?
RF-/STEEL Warping Torsion
For which programs is the STEEL Warping Torsion add-on module available?
Orthotropy Direction for Layers
Why cannot I define a rotation when defining layers?
Question
Can I rotate a foundation about the Z-axis in the RF‑FOUNDATION Pro add-on module?
AISC 341 Limit State Types
Which Limit State Types are applicable for the AISC 341 seismic design?
Question
Is there a way to prepare an EC3 buckling check without setting the intermediate support manually, or is there a workaround that can speed this up?
Cable and Tensile Structures
I would like to analyze cable and tensile structures. Is it possible to use RFEM or RSTAB for this?
