What is the difference between the RF‑/STEEL and RF‑/STEEL EC3 add-on modules?

Answer

Even if the description of the add-on modules is very similar, the calculations performed are different.

RF-/STEEL

This add-on module performs a general stress analysis by calculating the existing stresses and comparing them with the limit stresses. The designs are performed elastically. The designs do not depend on a standard.

RF-STEEL EC3

This add-on module, on the other hand, performs all typical designs of ultimate limit state, stability, deformation, and fire resistance for steel members according to Eurocode 3 (numerous National Annexes are available). There is a range of module extensions available within this add-on module. These include: warping torsion analysis, plasticity analysis, designs for cold-formed sections.

Comparison of Both Add-on Modules

The results of RF‑/STEEL can be compared with the results of the cross-section design of RF‑/STEEL EC3.

Why the results can differ is explained in FAQ 003489.
