What is the procedure for performing an earthquake analysis in RFEM/RSTAB?

Answer

For an earthquake analysis, the RF-/DYNAM Pro - Natural Vibrations and RF-/DYNAM Pro - Equivalent Loads add-on modules are available. Thus, it is possible 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.

In addition, you can evaluate the projectile displacement and the horizontal shear of the building. These and other features are described in detail in the webinar "Seismic Analysis in RFEM ".
