These load positions can be generated in the RF-MOVE or RSMOVE add-on module: Model File under Downloads includes two cases of moving loads (Crane A and Crane B). There are 50 load cases resulting for the moving loads only.
The load cases are then combined automatically. In the "Actions" tab, you can specify the effect of the load cases to each other. For this, the load cases for Crane A are assigned to Group 1, the load cases for Crane B to Group 2. This means that all combinations of Crane A are mutually exclusive. The same applies to Crane B. However, the load cases of Crane A can be combined with the load cases of Crane B.
Further information on moving loads and the combination of actions can be found in our manuals.
Define several load cases to create a moving load. Each load case should correspond to a certain position of the moving load in the structure.
You can easily generate the load cases from the load positions on members in the add-on modules RF-MOVE (for RFEM) and RSMOVE (for RSTAB). Using RF-MOVE Surfaces, it is also possible to generate load cases from moving loads on surfaces in RFEM (see the figure).
For a load distribution arranged horizontally (checkerboard-like), it is necessary to create a separate load case manually for each relevant loading zone (see figure).
When automatically combining the actions that can be specified in the "General Data" of the model, all possible load positions are taken into account.
