Answer:
Many webinars and online videos explain the automatic load combination, for example, for Eurocode. An example of this can be found on YouTube.
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 in RFEM 5 or RSTAB 8 just as easily and flexibly as the combination for the ultimate limit state (ULS) or the serviceability limit state (SLS). This generation is shown in the attached video.
In summary, the following steps are necessary (the structure and load cases are already defined):
- Activating the automatic generation of the combination in the General Data (Image 01)
- In the "Combination Expressions" tab, select the accidental combination with psi1 or psi2 as leading (Image 02).
- Ideally, create the combinations with an enveloping result combination.
- Select the created result combination for design in the add-on module, for example RF‑/TIMBER Pro, under the "Fire Resistance" tab.
