I measured a wall with RF-BETON surfaces. On the outside and inside I get the same amount of reinforcement [cm² / m]. Do I have to insert A s, top + A s, below ? Or just one value (either above or below)?

Answer

In RF-CONCRETE Surfaces, the "top" or "bottom" position is controlled by the orientation of the area's local coordinate system.

See also the FAQ000740

This means for a wall that As, below or As, above can either be the reinforcement on the outside or inside depending on the orientation of the local z-axis.

Both values must be taken into account for the reinforcement planning.
So the sum of A s, below + A s, above .
