### Bar bending schedule offers the reinforcement calculation for bolstered concrete beam. It offers particulars of reinforcement slicing size, kind of bends and bend size.

We are going to take one instance for reinforcement amount calculations for a concrete beam.

## Instance No. 2:  RCC Beam Reinforcement Calculation (Written Under):

Take into account a beam of clear size of 4m, 300mm large by 450mm depth. It consists of 2-12 diameter bars at high, and 2-16 diameter and 1 – 12 diameter bars on the backside. Diameter of stirrup is 8mm spaced at 180mm middle to middle. Clear cowl to reinforcement supplied is 40mm.

Now we’ll calculate the size of reinforcement primarily based on shapes of reinforcement required for bolstered concrete beam in above instance.
We are going to begin with backside reinforcement, B1.
Bar form of B1 is as proven under:
Size of B1 = clear distance between partitions + 2 x width of partitions – 2 x bar cowl + 2 x bend size
Bend size = 6 x 16 = 96 think about as 100mm
Bend size is calculated as 6 x diameter of bar for reinforcement conforming to IS: 1786-1961
Size of B1 = 4000 + 2 x 230 – 2 x 40 + 2 x100 = 4580mm
Size of bar B2 is calculated primarily based on form of this bar. This bar bends up close to the help as proven under:
Size of bar B2: A + B + C = 4000 + 2 x 230 – 2 x 40 + (1.414xH – H)
H = 450 – 2 x 40 – 2 x 12 – 2 x 12/2 = 334mm
B2 = 4000 + 2 x 230 – 2 x 40 + (1.414×334 – 334) = 4518.3 = 4520mm
Size of Bar T1 = 4000 + 2 x 230 -2 x 40 = 4380mm
Size of Stirrups S1:
Stirrups are spaced at 180mm middle to middle. Stirrups are supplied between partitions or help for a beam.No. of stirrups required for given beam = Size a = 450 – 2 x40 – 8 = 362mm
Size b = 300 – 2 x 40 – 8 = 212mm
Subsequently size of 1 stirrup S1 = 2 x (212 + 362 + 90) = 1328 mm
The place 90mm is the minimal hook size as per IS 2502 – Desk – II.
