Is it possible to consider the second-order theory in a dynamic analysis in RSTAB?


There is a detailed technical article for considering the second-order theory in a dynamic analysis in RFEM (see the link at the end of the FAQ). This article describes primarily the usage of the RF‑DYNAM Pro - Equivalent Loads add-on module. This add-on module does not allow for any consideration in RSTAB.

In order to correctly display the second-order theory in RSTAB, it is necessary to use the DYNAM Pro - Forced Vibrations add-on module. In this add-on module, the results are fully calculated within the add-on module. If you wanted to export the load cases first, the internal forces could not be calculated with regard to the modified stiffness matrix.
