Answer:
For seismic design, the add-on modules RF‑/DYNAM Pro – Natural Vibrations and RF‑/DYNAM Pro – Equivalent Loads are available in RFEM 5 and RTSTAB 8. They allow you to perform the multimodal response spectrum analysis. After the analysis in the add-on modules, the calculated seismic loads are exported to load cases, which can be evaluated as usual.

- RF-/DYNAM Pro - Equivalent Loads Add-on Module for RFEM 5/RSTAB 8
Furthermore, you can evaluate the story drift and the horizontal shear of the building. These and other features are described in detail in the webinar "Response Spectrum Analysis in RFEM".
