Different Moments in RF-/STEEL EC3 Due to Maximum Moments

When analyzing a member in RF‑/STEEL EC3, the result windows show a difference between the moments listed in the design internal forces and the moments used in the design. What has caused this difference?

Answer:

If this difference occurs in the design of Bending and compression according to 6.3.3, you can find the explanation in Eurocode 1993‑1‑1 6.3.3. (4). The following is written in the explanations of the variables: "the design values of the nominal compressive force and the applied maximum moments." The emphasis should be on "maximum". Consequently, in the case of a design by x-location, the corresponding axial force is applied in each case, but the maximum moments are applied to the member or member set.
