In RF‑PUNCH Pro, the '1.4 Longitudinal Reinforcement' dialog box shows all surfaces connected to the nodes selected for design. So in the case of punching shear design on a wall corner, for example, it shows the surfaces that actually represent the walls. I can also define longitudinal reinforcement for these surfaces. Is this somehow recognized? Why do I see these surfaces in the dialog box 1.4?


You are right. In the '1.4 Longitudinal Reinforcement' dialog box, all surfaces connected to the nodes selected node for design are displayed first. This also includes the walls in the wall corner that you have mentioned.

However, the definition of the position of the longitudinal reinforcement for these walls is not relevant for the punching design in the floor slab.

As of the RFEM version 5.19.01, a filter has been installed, which you can use to only display the surfaces for which the definition of the position of the longitudinal reinforcement is relevant.

You can find the filter button in the input dialog box 1.4 on the bottom right. See Figure 01.
