Answer:
With the Equivalent Loads and Forced Vibrations add-on modules, you can create result combinations that contain the governing combinations of seismic loads. To perform the design using them, they have to be combined further on the basis of the accidental combination. This combination is defined, for example, in EN 1990, Section 6.4.3.4:
This accidental combination has to be defined manually in RFEM. Make sure that (for a direction combination with the 100/30% rule), both created result combinations from RF‑/DYNAM Pro have to be added with the "OR" condition. Such a combination is displayed in Image 02.
This accidental combination can then be used for further design. It is possible to evaluate the governing internal forces as well as to import and calculate this combination in the design modules.
