FAQ 004443 | What is the meaning of a "main load" and "secondary load" in RF‑PUNCH Pro, and where does this load come from?

Question:
What is the meaning of a "main load" and "secondary load" in RF‑PUNCH Pro, and where does this load come from?

Answer:
In RF‑PUNCH Pro, a primary and secondary load are determined when introducing a compression and tensile force at a point of punching shear (for example, a column). For example, this may be the case when calculating a result combination (RC) that results from a previous dynamic analysis with RF‑/DYNAM Pro.

In this case, the tensile and compressive forces may occur at the connection of a column to a slab. The add-on module analyzes both "punching directions" individually and displays them as "primary load" and "secondary load".
