The projection plane and the load direction are different parameters and independent of each other.
While the load direction represents the actual direction of the acting load, the projection plane, together with the corresponding coordinates of the load position, describes the plane from which the load's position is projected onto the surfaces subjected to the load.
In the "Edit Free Rectangular Load" dialog box, the graphic to the right is used for information purposes, see Figure 01.
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 an arrangement of the loads by span (chessboard-like), it is necessary to create a separate load for each span that is to be loaded (see the figure).
All possible load positions are then considered for the automatic combinations of the actions, which can be specified in "General Data" of the model.

Wind Simulation & Wind Load Generation
With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
“Thank you for the valuable information.
I would like to pay a compliment to your support team. I am always impressed how quickly and professionally the questions are answered. I have used a lot of software with a support contract in the field of structural analysis, but your support is by far the best. ”
