What should be considered when using a failure of columns under tension in the RF‑/DYNAM Pro – Equivalent Loads add-on module?

Answer

In order to consider the failure of certain members when using RF‑/DYNAM Pro – Equivalent Loads, proceed as follows:

1) Deactivating the corresponding members for the eigenvalue determination within the corresponding load case, see Image 01 (add-on module, tab Natural Vibration Cases, Calculation Parameters) and Image 02 (main program, Calculation Parameters, Deactivate and select).

Image 01 - Natural Vibration Cases - Stiffness Modifications

Image 02 - Deactivating Members in Original Load Case

2) Determining dynamic load cases from RF‑/DYNAM Pro by using the calculation, then deactivating the corresponding member in the main program within the global calculation parameters of the dynamic load cases, see Image 03.
