Question

When calculating a case of RF‑/JOINTS Steel - Column Base, I get Message No. 48335 saying that the bending moment Mz exceeds 5% of the plastic moment resistance. What does it mean?


Answer:
The analysis of a rigid column base is performed according to EN 1993‑1‑8 in the RF‑/JOINTS Steel - Column Base add-on module. The standard only provides simple bending in the design format. The design can be performed for pure compression, tension, simple bending, or a combination of bending and tension, or bending and compression. If you click "Yes" to confirm the message, the add-on module performs all designs without taking into account the unsupported internal force Mz.
