Question

What is the meaning of a "positive" and a "negative" surface side?


Answer:

The "+" and "-" signs for 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 my,D+ is, for example, the governing bending moment for the reinforcement on the positive surface side.
