Question:
Can I also use the automatic generation of accidental combinations for fire resistance, for example?
Answer:
Many webinars and online videos explain the automatic load combination, for example, for Eurocode. An example of this can be found directly on YouTube here.
However, due to time reasons, these webinars and videos often do not include any accidental combinations, such as those necessary for a fire situation or earthquake.
Such a combination can be generated just as easily and flexibly as the combination for the ultimate limit state (ULS) or the serviceability limit state (SLS).
The generation of the combination is shown in the attached video.
In summary, the following steps are necessary (the structure and load cases are already defined):
1.
Activating the automatic generation of the combination in the General Data (Image 01)
2.
In the Combination Expressions tab, select the accidental combination with psi-1 or psi-2 as leading (Image 02).
3.
Ideally, create the combinations with an enveloping result combination.
4.
Select the created result combination for design in the add-on module, for example RF‑/TIMBER Pro, under the "Fire Resistance" tab.
