Complex Square and Rectangle Formed Rebar Center Line Length Equation and Calculator

 

L = A + B + C + 2 D + E + F - 3 r - 6 d

Where:

L = Center line length (in, mm)
A = Leg length (in, mm)
B = Leg length (in, mm)
C = Leg length (in, mm)
D = Leg length (in, mm)
E = Leg length (in, mm)
F = Leg length (in, mm)
d = Rebar Diameter (in, mm)
r = Rebar radius (in, mm)

Note: Keep all units consistant, typical units shown.
