Is the punching load in RF-PUNCH Pro taken from the support forces of the line supports for the check on a wall corner? Which lengths are decisive for applying the support forces?


RF-PUNCH Pro uses the support forces only for the 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 even a punching load can be determined if a wall was 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 type of modeling.

You can also find additional information about determination of the punching load for wall corners and wall ends in an article on our homepage that you can open by clicking the following link.
