Bar Bending Schedule for Reinforcement Beam
Bar Bending Schedule for Reinforced Concrete Beam
Bar bending schedule provides the RCC Calculation for reinforced concrete beam. It provides details of the reinforcement cutting length, type of bends & bend length. We will take 1 example for reinforcement QTY calculations for a Concrete Beam.
Example of the Beam Reinforcement Calculation.
Consider a beam of clear length of 4m, 300mm wide by 450mm depth. It consists of 212 diameter bars at top, & 216 diameter & 1 – 12 diameter bars at the bottom. Diameter of stirrup is 8mm spaced at 180mm center to center. Clear cover to reinforcement provided is 40mm.
Now we will calculate the length of the reinforcement based on shapes of the reinforcement required for reinforced concrete beam in above example. We will start with bottom reinforcement, B1. Bar shape of B1 is as shown below.

Length of B1 = Clear distance between walls + two x width of walls – two x bar cover + two x bend length Bend length = Six x 16 = 96 consider as 100mm Bend length is calculated as 6 x diameter of the bar for reinforcement conforming to IS: 1786 1961 Length of B1 = 4000 + two x 230 – two x 40 + 2 x100 = 4580mm Length of bar B2 is calculated based on the shape of this bar. This bar bends up near the support as shown below.
Length of bar B2: A + B + C = 4000 + two x 230 – two x 40 + (1.414xH – H) H = 450 – two x 40 – two x 12 – two x 12/2 = 334mm B2 = 4000 + 2 x 230 – two x 40 + (1.414 x 334 – 334) = 4518.3 = 4520mm Length of the Bar T1 = 4000 + two x 230 – two x 40 = 4380mm Length of Stirrups S1:
