Calculation RFEM RF-CONCRETE

What does "positive" and "negative" surface mean?

Answer

The "+" and "-" for the design internal forces and stresses indicate the side of the surface.

The positive side "+" is the one with the local z-axis pointing outwards.

The design internal force m-y,D+ is, for example, the governing bending moment for the reinforcement on the positive surface side.
