* “X” Min. Type 1 and “Y” Min. Type 1 will develop 125% of the specified yield strength of the rebar in tension and compression ( 125% fy ).
** “X” Min. Type 2 and “Y” Min. Type 2 meet Type 1 and will develop the specified tensile strength of the rebar in tension ( fu ).

To Determine Typical Cut Length of
Reinforcing Steel:
Maximum Cut Length
Gravity Condition =
[Overall Panel Height - E]
+ Sealing Mortar Height
Pump Condition =
[Overall Panel Height - E - Xmax]
+ Ymax + Sealing Mortar Height
Minimum Cut Length =
Maximum Cut Length - 1 Bar Diameter
Dowel Length =
X + Sealing Mortar Height
Y + Sealing Mortar Height
Note: For last lift, reduce cut length as
determined by design requirements.
