Question

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 have to enter As,top + As,bottom now? Or only one value (top or bottom)?


Answer:
In RF‑CONCRETE Surfaces, the "Top" or "Bottom" position is controlled by the orientation of the local coordinate system of the surface.

For more information, see also FAQ000740

For a wall, this means that As,bottom or As,top can be the reinforcement on the outside or inside depending on the orientation of the local z-axis.

Both values must be considered for the reinforcement design.
That is, the sum of As,bottom + As,top.
