Please check if there is no mistake in units in the model when entering the width t of the "Wall in Z." The entry must be in "mm" at this location in the program.
If the width t is specified in cm instead of mm, RF‑PUNCH Pro does not recognize the wall end or wall corner.
As soon as the entry has been corrected, the node can be selected again for the design in RF‑PUNCH Pro.
AnswerRF-PUNCH Pro only uses the support forces in the case of punching shear designs of nodal supports.For the punching shear design on wall corners and ends, the shear force in the critical perimeter is used instead of the support force of the line supports. This has the advantage that it is also possible to determine the punching load even if a wall has been entered in a 3D model instead of a line support. Thus, this approach in the add-on module is more general and can be applied regardless of the modeling type.Further information about determining the punching load on wall corners and wall ends can be found in the technical article on our homepage, which you can open by using the following link.
The line support type "wall" is actually intended for ceiling slabs that, for example, rest on a masonry wall with elastic foundations. Therefore, this tool is only allowed for horizontal surfaces. Spring stiffness of the wall is calculated and applied in the calculation.
If the surfaces are not in a horizontal position, the spring must be entered manually.
In order to use the spring stiffnesses of a wall as a reference point for your own entry, you can first define the wall and then unselect the "Wall" option: the determined spring properties stay in the text boxes and can be modified.

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. ”
