Export of Response Spectrum
Answer
Yes, you can also export the response spectra from RFEM 6 and import them into RFEM 5 as a user-defined response spectrum. Please note that the export and import via Excel may also have different columns/descriptions due to the different versions.
Export your data in RFEM 6 to Excel.
If you want to import this table directly, you will get an error message. RFEM 5 expects a different worksheet description and two columns only.
As soon as you adjust the name in Excel and delete the column with the frequency results, you will be able to edit the response spectrum in RFEM 5.

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 | Neglecting Masses
It is often necessary to neglect masses, especially when the output of the modal analysis is to be used by the seismic analysis, where 90% of the effective modal mass in each direction is required for the calculation. Thus, you can neglect masses in all fixed nodal and line supports so that the program will automatically deactivate the masses associated with them, but you can also manually select the objects for which the masses should be neglected in the modal analysis. The latter is shown in the image, where a user-defined selection is preferred, and the objects as well as their associated mass components are selected to neglect the masses.
