Bar Bending schedule For Footing :-
FOOTING
Details Obtained from
Structural Drawing
Following details are obtained from the drawings and
specifications:
- Length
of Footing = X
- The
breadth of Footing = Y
- The
height of the footing (Thickness) = h
- The diameter of the Main
reinforcement bars = dm
- The diameter of Distribution
Reinforcement Bars = dd
- The
spacing of reinforcement bars = s
- Cover for reinforcement = c
Formulas for Calculation
From the figure-1, the following parameters are determined:
- Number
of Main Reinforcement Bars ( X-Bars)
- Number
of Distribution Reinforcement Bars ( Y-Bars)
- Cutting
Length of Main Reinforcement Bars (Cm)
- Cutting
Length of Distribution Reinforcement Bars (Cd)
- Steel Quantity Required
Footing:-
1. Cutting Length of Main Reinforcement
(X-Bars) Cm1 = [Length of Footing
– 2(cover)] +2[ Thickness of footing -2(cover)] - 2[Bend] From the figure,
Cm1 = [X-2C] +2[h-2C]-2[2dm]
2. Cutting Length of Distribution Reinforcement (Y-Bars) Cd= [Breadth of Footing – 2(cover)] +2[ Thickness of footing -2(cover)] - 2[Bend] From the figure,
Cd1
= [Y-2C] +2[h-2C]-2[2dm]
