Rectangle With Inward-formed Sections Center Line Length Equation and Calculator
If 14 d > 150
L = 2 A + 3 B + 14 d
If 150 ≥ 14 d
L = 2 A + 3 B + 150
Where:
L = Center line length (mm)
A = Leg length (mm)
B = Leg length (mm)
C = Leg length (mm)
D = Leg length (mm)
d = Rebar Diameter (mm)
r = Rebar radius (mm)
Note: Keep all units consistant, typical units shown.
