Features of the Modal Analysis Add-on for RFEM 6
The dynamic analysis in RFEM 6 and RSTAB 9 is divided into several add-ons. This article will show you some of the main features of the Modal Analysis Add-on for RFEM 6 / RSTAB 9.

Modal Analysis | Visualization and Standardization of Mode Shapes
As already mentioned, the results of a Modal Analysis load case are displayed in the program after a successful calculation. Hence, you can immediately see the first mode shape graphically or as an animation. The representation of the mode shape standardization can be easily adjusted. You can do this directly in the Results navigator, where you should select one of the three options for the visualization of the mode shapes: scale the value of the mode shape vector uj to 1 (considers only the translation components); select the maximum translational component of the eigenvector and set it to 1; or consider the entire eigenvector (including the rotation components), select the maximum, and set it to 1.- 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?
- Is the German National Annex 2021‑07 to Eurocode 8 available in RFEM 5 / RSTAB 8?
- 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?
