How do you usually call each set of extra bars when doing curtailment of reinforcement?

[asiga]

When extra bars from curtailed reinforcements are cut-off at different points, how do you usually call each "set" of extra bars that have the same length?

"Set"? "Family"? "Bundle"?

For example, at the picture above, would you say that there are three (sets/families/bundles/or what?) of extra bars both for the negative and for the positive bending moment.

Thanks a lot in advance!!
