Paul Kieloch Modeling | Loading RFEM RSTAB

Do I use the load cases or the load or result combinations for the analyzing in the add-on modules? Does the corresponding add-on module (e.g. RF-/FOUNDATION Pro) automatically create the required load combinations for me?


Basically, you should select the design load for the verification which relates to the design situation to be analyzed for the design conduct. For example “ULS” or “SLS”.

Now, it is important that the add-on modules in RFEM or RSTAB do not automatically generate these design load cases. That is, it is not sufficient to select only the load cases in the add-on modules. Before starting the design process, you have to either create or generate load combinations or result combinations in the add-on modules.

Afterward, these load or result combinations can be applied for the design in the add-on modules.

However, if you want to explicitly carry out the design in an add-on module for a specific load case, you can select it for the design. If several single load cases are selected for design, the design is performed consecutively by load cases.
