Area of bars in pairs

Area of bars in pairs

Hi Engineers,
Could someone clarify the statement; “area of bar in pairs”? I came across this in a steel reinforcement area table from an RC Workbook and I am wondering if this is applicable to RC Walls. Please see attached.
Any other references would be much appreciated.

RE: Area of bars in pairs

This could be referring to the effective area to consider for bond length when splicing bundled bars. Do you have a reference where you read the term?

Just the sum of two bars. I don't know why you would want the table, but it could be used wherever you have paired bars, e.g. Wall bars each side, beam stirrups.
