How can I perform an earthquake analysis in RFEM 6 and RSTAB 9?

Answer

To perform an earthquake analysis, you need a modal analysis and then a load case of the Response Spectrum Analysis type.

After you have performed your modal analysis, create a new load case. Here you will find the usual settings from the previous program generation.


In the Response Spectrum tab, you can define your response spectrum as usual. If you want to use a response spectrum according to the standard, make sure that the desired standard is selected in the general data of Standards II.



In the Selection of Modes tab, you can select the mode shapes and filter them, if necessary.


After the load case has been calculated, you obtain the results.
