How does RF‑PUNCH Pro calculate the VEd values of the punching load?


RF-PUNCH Pro does not determine the punching load by adding support loads, but directly from shear forces of a plate in the critical perimeter.

When comparing with a control calculation, there might be discrepancy in the results as the punching load is influenced by the FE mesh and possibly also by singularity effects in the FE calculation.

A detailed description of the method used in RF‑PUNCH Pro can be found in the technical article in our Knowledge Base, which you can find under Links below.
