Bars that very in only one bend dimension can be easily described as "varies" bars instead of describing each bar individually.
Consider the vertical reinforcement in an abutment wall with a sloping top. Every vertical bar along the face of the wall is a Type 54 (there is 9 in all) and each bar has a different length ranging from 8''-0" to 10''-0" (U dimension).
In the No. Required field, enter 9 because there are 9 bars in all. Check the Varies box and enter 1 in the No. Each field. This means there is one bar at each length (8ft, 8.25ft, 8.50ft, 8.75ft, 9,ft, 9.25ft, 9.50ft, 9.75ft, 10ft)
An alternative bar configuration would be to use 9 bars, with 3 bars at each length (3@8ft, 3@9ft, and 3@10ft). In this case enter 3 in the No. Each field because there are three bars at each length.
