Question

Why do I get the message 28) in RF‑CONCRETE Members, saying that I have to make a "calculation without second order effect" with the internal forces according to the gemetrically linear analysis?

Answer

RF-CONCRETE Columns determines the equivalent moment M0e from the moment M02 at the column head and M01 at the column base according to EN 1992‑1‑1, 5.8.8.2 (2), and performs the design according to the model column method with this equivalent moment M0e.

Now, it may happen, for example, that a computationally larger required reinforcement area would result from the cross-section design with the moment M01 at the column head.

To ensure this, message 28) is displayed, according to which the user should perform a standard design with the internal forces according to the linear static analysis. To do this, simply open the RF‑CONCRETE Members add-on module and perform pure design of the internal forces according to the linear static analysis for the member designed in RF‑CONCRETE Columns.
