In RF-PUNCH Pro, you can perform the punching shear design on wall corners and wall ends. The basis for the design is the punching load, which is automatically determined from the RFEM internal forces in the connected surface. Since the surface internal forces from the RFEM calculation can be subject to the influence of singularities, this can also have a negative effect on the determined punching load at the wall corner/end. This article describes possible optimization options that you can use to minimize this unfavorable effect.
