Seismic Analysis in RFEM 6 is possible by using the modal analysis and the response spectrum analysis add-ons. As a matter of fact, the general concept of the earthquake analysis in RFEM 6 is based on the creation of a load case for the modal analysis and the response spectrum analysis, respectively. The standard group for these analyses are set in the Standards II tab of the model’s Base Data.

Compared to the RF-/DYNAM Pro - Natural Vibrations add-on module (RFEM 5 / RSTAB 8), the following new features have been added to the Modal Analysis add-on for RFEM 6 / RSTAB 9:
- Preset combination coefficients for various standards (EC 8, ASCE, etc.)
- Optional neglect of masses (e.g. mass of foundations)
- Methods for determining the number of mode shapes (user-defined, automatic - to reach effective modal mass factors, automatic - to reach the maximum natural frequency)
- Output of modal masses, effective modal masses, modal mass factors, and participation factors
- Tabular and graphical output of masses in mesh points
- Various scaling options for mode shapes in the result navigator
- How can I analyze the failure of an object, such as a column, in my modal analysis?
- Where can I adjust the standardization of a mode shape in RFEM 6 / RSTAB 9?
- How can I perform an earthquake analysis in RFEM 6 and RSTAB 9?
- Can I export a response spectrum from RFEM 6 and use it in RFEM 5, for example?
- How can I neglect masses in my modal analysis in RFEM 6 / RSTAB 9?
- Why do the results in a modal analysis differ between the initial prestress and the surface load?
- How can I display mode shapes in RFEM 6 and RSTAB 9?
- What is the meaning of the superposition according to the CQC rule in a dynamic analysis??
- There are two different add-on modules for a response spectrum analysis in RF‑/DYNAM Pro. What can be the reasons for the different results of both add-on modules?
- RF‑/DYNAM Pro - Forced Vibrations and RF‑/DYNAM Pro - Equivalent Loads perform the multi-modal response spectrum analysis. What are the differences?
