Question:
How do you define the descriptions of various reinforcement results, such as the required reinforcement?

Answer:
The descriptions of the reinforcement in the Results navigator are defined as follows:

A-s,-z (top):

Upper longitudinal reinforcement; that is, all longitudinal reinforcement that is above the centroidal axis of the cross-section (see Image 01)

A-s,+z (bottom):

Bottom longitudinal reinforcement; that is, all longitudinal reinforcement that is below the centroidal axis of the cross-section

A-s,T:

Total longitudinal reinforcement of the cross-section that is required due to torsion

A-s,-z (top) + A-s,T/2:

Upper longitudinal reinforcement (see above) plus one-half of the required longitudinal reinforcement from torsion

A-s,+z (bottom) + A-s,T/2:

Bottom longitudinal reinforcement (see above) plus one-half of the required longitudinal reinforcement from torsion

a-sw,T,stirrup:

Stirrup reinforcement from torsion
Always single-leg, which means: reinforcement content from one leg on one stirrup member
Resulting from the theoretical assumption of a spiral stirrup reinforcement

a-sw,V,stirrup:

Stirrup reinforcement from shear force
Two-, three-, or four-leg, which means: reinforcement content from one leg on two, three, or four stirrup members
Setting the number of legs under stirrup parameters, Window "1.6 Reinforcement", "Stirrups" tab; see Image 02

2*a-sw,T,stirrup + a-sw,V,stirrup:

Total stirrup reinforcement from torsion and shear force
In this case, two-leg for torsion, therefore Factor 2 before a-sw,T,stirrup, shear reinforcement according to the setting from Image 02
