Is it possible to apply the minimum bending moments according to DIN EN 1992‑1‑1 in RF‑PUNCH Pro?


Yes, it is possible. For this, open Window 1.5.

Figure 01 - Window "1.5 Nodes of Punching Shear" - Minimum Bending Moments - Condition Fulfilled

If there are too few nodes selected for design, so that the program cannot determine the dimensions lx or ly automatically according to DIN EN 1992‑1‑1, 6.4.5 (NA6), Figure NA 6.22.1, a message appears, saying that the conditions for determining the minimum bending moments are not fulfilled.

The program requires at least 4 nodes to determine the span lengths in the x- and y‑direction.

In this case, you can define the minimum bending moments manually.
