Question

I would like to perform the fire resistance design using the EC3 add-on module. Is it possible to intervene in the program in such a way that I can use my own temperature curve instead of the standard one?


Answer:
The method according to EC 3 can only be used for the temperature curves from EN 1990‑1‑2. With the simplified calculation of the steel temperature in EC 3‑1‑2, it is only possible to consider increasing temperature gradients; a decrease of the temperature is not available in this simplified calculation. However, it is also possible to use the direct steel temperatures in the program (see Image 01).
