Bar Bending Schedule For The Duct Bank
The duct bank is also called the conduit bank. duct bank is construction on that location where the electrical cable is passing under any road. in the duct bank, we use PVC conduit or pipe and also use rebar in construction duct bank.

Bar Bending Schedule For The Duct Bank
Bar bending schedule means we find the rebar by using the duct bank cutting length of rebar diameter of the rebar and weight of the rebar. we find also the fixing of the rebar location and spacing of the rebar in the duct bank.
Now we calculate the bar bending schedule for the duct bank with the help of the given data. given data is only, for example, to explain the all steps, and this example to get very easy all steps and correct information.
Given Data
length of the duct bank=8m
width of The duct bank = 1870mm=1.870m
height of duct bank=480mm
diameter of main bar=16mm
diameter of distribution bar=16mm
dia meter of sidebar =12mm
Spacing of all bar=150mm
Concrete Cover of all bar=75mm
Solution
Length of the main bar/bottom bar
weight of the main bar/bottom bar
length of distribution bar/top bar/long bar
Weight of distribution bar/top bar/long bar
length of sidebar
weight of sidebar
Length of the main bar
Cutting length of main bar= total width of duct bank2C.C+2 bends
Cutting length of main bar=18702(75)+2(20d)
Cutting length of main bar/bottom bar=1870150+2(20×16)=2360mm=2.360m
Number of bars
Number of bar=total length /spacing +1
Number of bar=8000/150+1=54.33=55nos
The total length of the main bar
Total length of main bar=Numbers of bar × cutting length
Total length of main bar= 55 × 2.360=129.8m
Weight of the main bar
Weight of main bar=d²/162.62×total length
Weight of main bar=16²/162.62×129.3=203.546kg=204kg
Same length and the same weight as the main bottom bar and main top bar
Total weight =Main bar bottom+Main bar top
Total weight =204kg+204kg=408KG
Length of distribution bar /long bar
Cutting length of distribution bar=total length of duct bank 2C.C+2 bends
Cutting length of distribution bar=80002(75) +2(20d)
Cutting length of distribution bar=8000150 +2(20×16)=8490m=8.490m
Number of distribution bar
Number of distribution bar=total width /spacing +1
Number of distribution bar=1870/150+1=13.466=14nos
Total length of distribution bar
Total Length of distribution bar=Number of bar × cutting length
Total Length of distribution bar=14 × 8.490=118.86m
Weight of distribution bar
Weight of distribution bar=d²/162.62×total length
Weight of distribution bar= 16²/162.62×118.86=187.112kg=188kg
Same length and the same weight as the distribution bar bottom and top bar
Total weight =distribution bar bottom+distribution bar top
Total weight =188+188=376kg
Total weight of 16mm bar=408+376=784kg
Length of sidebar/straight bar
Cutting length of sidebar=total length of duct bank 2C.C
Cutting length of sidebar=80002(75)=7850mm=7.850m
Number of sidebars
Number of sidebar=2
The total length of the Sidebar
The total length of Sidebar=Number of bars × cutting length
The total length of the Sidebar=2 × 7.850=15700mm=15.700m
Weight of sidebar
Weight of sidebar=d²/162.62×total length
Weight of sidebar=12²/162.62×15.700=13.902kg=14kg
