What is the bar bending schedule and how do you prepare it?
Table of bar bending schedule summarizes all the needed particulars of bars – diameter, shape of bending, length of each bent and straight portions, angles of bending, total length of each bar, and number of each type of bar. This information is a great help in preparing an estimate of quantities.
What is the formula for straight bar in bar bending schedule?
(ii) Bend Length calculation when bars are bent at corners:-
| Bar Shapes | Total Length of Hooks | Total Length of Bar |
|---|---|---|
| Double Bent up Bar | Two Hooks = 9d + 9d = 18d | l + 18D + 0.42D + 0.42D =l+18D+0.84D |
| Overlap of bars | Two Hooks = 9d + 9d = 18d | Overlap Length =(40d to 45d)+18d |

How is bar bending calculated?
Bar Bending Schedule for Reinforced Concrete Beam
- Length of B1 = clear distance between walls + 2 x width of walls – 2 x bar cover + 2 x bend length.
- Length of bar B2: A + B + C = 4000 + 2 x 230 – 2 x 40 + (1.414xH – H)
- B2 = 4000 + 2 x 230 – 2 x 40 + (1.414×334 – 334) = 4518.3 = 4520mm.

How do you calculate water tank load?
Capacity Calculation Formula
- Total Water Requirement = Number of persons X Minimum Water requirement = 10 X 135 Litres = 1350 Litres.
- We know, 1 m3 = 1000 litres of water.
- So the required storage volume for 1350 Litres = 1.35 Cubic Metre.
- Now we have calculated the volume of water requirement.
