Question
What is the formula used to calculate the ASCE 7 wind velocity profile?
Question
I would like to connect a column rigidly to a girder flange. However, in the RF‑/JOINTS Steel - Rigid add-on module, beams are always connected to a column flange. How can I create a continuous beam?
Question
How do I create a frame joint with taper in JOINTS Steel - Rigid?
Question
How do you perform a lateral-torsional buckling analysis for asymmetric steel cross-sections?
Question
Is the Gust-effect (G or Gf) from the ASCE 7‑16 Sect. 26.11 considered in RWIND Simulation?
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)?
Frame Joint
Is it possible to use one of the RFEM 5 / RSTAB 8 add-on modules to design a frame joint with a docked beam, stiffeners, and any number of bolt rows?
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?
Question
Is it possible to generate wind loads according to DIN EN 13782 with this program?
Splice Connection
How do I create a splice connection in the Steel Joints add-on?
Question
What does the load application point in RF‑/STEEL EC3 Warping Torsion refer to?
Question
When calculating a connection using the FRAME‑JOINT Pro add-on module, a message appears saying that the value is out of the valid range (existing value: 108, minimum value 100, maximum value 100). What does this message mean?
Question
When entering data in the RF‑/STEEL EC3 add-on module, I get the error message "Incorrect location of the intermediate lateral restraint". Why?
Question
The welds of a column head plate are very small. What is the reason?
Question
What is the meaning of the abbreviations for the crane loads in the CRANEWAY add-on module?
Question
In RF‑/JOINTS Steel - DSTV, I get the notes "Wrong geometry" and "Invalid material". Which entries do I have to adjust?
Question
How can I optimize the calculation time in CRANEWAY?
Question
I am performing a stability analysis according to the second-order analysis. Why is the partial safety factor γM1 used for the stress analysis here?
Question
Why do I obtain different results for the same end plate joint in RF‑/JOINTS Steel - DSTV and RF‑/JOINTS Steel - Rigid?
Boundary Moments in Warping Torsion
I use RF-/STEEL Warping Torsion to design an eccentrically modeled wall beam, which is loaded transversely with a distributed load. While the bending moments in the main program are zero at the member start and member end due to the hinges, RF‑/STEEL Warping Torsion outputs moments there. Thus, the span moment is reduced incorrectly. How do I get the boundary moments to zero?
Question
For design in FRAME‑JOINT Pro, I get Error No. 30011 "The selected nodes have different geometry [...]." How can I design my connection?
Question
I designed a steel connection using RF‑JOINTS, then created a model to compare it in RFEM. Why are the results not identical?
Question
When modeling a beam connection to a continuous column, I have the problem that the column flange fails under bending. If I add backing plates in the FRAME‑JOINT Pro add-on module, nothing changes for all design ratios. Why?
Question
Can I consider the normal force when designing a rigid end plate connection according to the DSTV guideline?
Question
Which result combinations can I design with the RF‑/JOINTS Pro program, and what should I pay attention to?
Question
Is it also possible to design individual hollow sections using the HSS add‑on module?
