This model is for a student tutorial where it is used as an example for how to enter the input data needed to design steel members in the RF-STEEL AISC module.
Model Used in
Utilizing the RF-STEEL AISC add-on module, steel member design is possible according to the AISC 360-16 standard. The following article will compare the results between calculating lateral torsional buckling according to Chapter F and eigenvalue analysis.
SHAPE-THIN determines the effective cross-sections according to EN 1993-1-3 and EN 1993-1-5 for cold-formed sections. You can optionally check the geometric conditions for the applicability of the standard specified in EN 1993‑1‑3, Section 5.2.
The effects of local plate buckling are considered according to the method of reduced widths and the possible buckling of stiffeners (instability) is considered for stiffened sections according to EN 1993-1-3, Section 5.5.
As an option, you can perform an iterative calculation to optimize the effective cross-section.
You can display the effective cross-sections graphically.

Why are my steel members not being designed for stability in RF-STEEL AISC?
- Can RF-STEEL AISC optimize cross-sections for Serviceabillity?
- 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?
- Does RF-STEEL AISC perform torsion design per Design Guide No. 9?
- 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?
- How is the automatic creation of c/t-parts carried out?
- I design a set of members by using the equivalent member method in RF‑/STEEL EC3, but the calculation fails. The system is unstable, delivering the message "Non-designable - ER055) Zero value of the critical moment on the segment."What could be the reason?
- My aim is to mesh a circular hole plate in a mapped way. Is such a meshing possible in RFEM?
- The design ratio of the cross-section check is different for the RF‑/STEEL and RF‑/STEEL EC3 add-on module. What is the reason?
- What is the meaning of the warning message ER061) Minimum amplifier of design loads <1?
