AnswerRF-PUNCH Pro uses the support forces only for the punch supports for nodal supports.For the punching shear design on wall corners and ends, the member behavior is not used as the support force from the line supports but as the shear force in the critical perimeter. This has the advantage that a punching load can also 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 determining the punching load for wall corners and wall ends in an article on our homepage that you can open by clicking 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.
