I would like to perform seismic design of an irregular structure. Does RFEM automatically carry out the modal analysis (consideration of multiple vibration modes) on the spatial system, or do I have to use special settings for this?
In the RF‑/DYNAM Pro - Equivalent Loads add-on module, it is possible to consider accidental torsional actions. Which calculation approach is behind the calculation? Which values have to be entered for the eccentricities eX and eY?
