I designed a wall with RF-CONCRETE Surfaces. On the outside and inside, the program shows me the same reinforcement amount [cm² / m]. Do I now have to insert A s, top + A s, bottom ? Or only one value (top or bottom)?


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 .
