Question
What is the formula used to calculate the ASCE 7 wind velocity profile?
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)?
Effective Lengths for Steel Stability Design
How do I define effective lengths when designing steel members in RFEM 6?
ASCE 7 Seismic Load Combinations
I do not see the seismic load cases in my generated ASCE 7 load combinations (COs). How do I add them?
ASCE 7 Orthogonal Directional Combination Procedure
How do I apply the ASCE 7 Orthogonal Directional Combination procedure (100% + 30% rule) to my seismic load in a static analysis?
Question
I would like to calculate a hall frame with loads from a crane runway. It is not quite clear to me what the various action categories denote. Can you explain it to me?
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
How can I determine loads at particular geographic coordinates in the online service "Snow Load, Wind Speed, and Seismic Load Maps"?
Question
Is it possible to perform automatic live load reduction in RFEM or RSTAB per the ASCE, IBC, or NBCC?
Question
How are the location-specific Geo-Zone Tool data queries calculated for the determination of various building loads?
Question
RF‑STEEL AISC add-module shows non-designable results for general cross-sections because of shear buckling checks according to Chapter G. How do I solve this?
Question
After running the design in RF‑STEEL AISC, I receive error message 1002 - Invalid cross-section of type "Channel" according to F2. What does this error mean?
Question
Is it possible to generate wind loads according to DIN EN 13782 with this program?
Overstrength Factors
How do I include the overstrength factor(s) Ωo in the ASCE 7 load combinations?
Question
Why is the load value displayed in the online service "Geo-Zone Tool: Snow Load, Wind Speed, and Seismic Load Maps" different from the value in the corresponding standard in some cases?
Splice Connection
How do I create a splice connection in the Steel Joints add-on?
Redundancy Factors
How do I include the redundancy factor(s) ρ in the ASCE 7 load combinations?
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?
ASCE 7 Reduced Live Load Factor
My live load is less than or equal to 100 psf. How do I consider the reduced load factor in the ASCE 7 load combinations?
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?
Question
Does RF‑STEEL AISC perform torsion design per Design Guide No. 9?
Question
When designing seismic equivalent loads with a Response Spectra Analysis (RSA) in RFEM, how can I apply the modal response parameters Ie/R according to Sect. 12.9.1.2 in the ASCE‑7‑16 to my results?
Question
Is it also possible to integrate the online service "Snow Load, Wind Speed, and Seismic Load Maps" into external applications?
Question
I am performing a design in RF‑/STEEL AISC for result combinations from RF‑/DYNAM Pro and get the error message "Not designable - Null value of the critical moment on the segment". What should I do?
