In RF‑CONCRETE Columns, I get a design ratio > 1 for the fire resistance design. How can the design be fulfilled in the add-on module?

Answer

The add-on module determines the required reinforcement for the ultimate limit state. The fire resistance design is performed as design based on the determined reinforcement. The reinforcement will not be increased in this process. If the design is not fulfilled, you can either define a higher reinforcement manually or adjust the concrete cover to prevent the applied reinforcement from being damaged too much by the effects of fire.
