What Is The Duct Bank?
Duck band is the Reinforcement concrete members like the horizontal under the road crossing. the basic uses of the duck bank is crossing cable under the road with the conduit. this is also called cable conduit bank. duck bank is the different sizes as par requirements. one conduit layers of the duck bank two conduit layers of the duck bank. For The Construction of the duck bank is must be know the bar bending schedule. how to calculate the bar bending schedule for the duck bank. In the bar bending schedule is mentioned dia of the bar length of the bar and weight of the bar and how to fixing the bar in the duck bank. this all details is mention in the bar bending schedule.
Calculate the bar bending schedule for the bank
Calculate the bar bending schedule for the bank is bellow mentioned all step and detail.as par given detail.
Given Die mention
Lenght =7.5m
Width=1.870m
Thicknes/Height=480mm
Dia of the main bar=16mm
Dia of the Distribution bar=16mm
Dia of the side bar=12mm
Spacing between all bar=150mm
Concrete covery (C.C)=75mm
Now calculate the Solution
Steps of calculation
1- Length of bottom bar /main bar
2- Weight of bottom bar/main bar
3- Length of top long bar/distribution bar
4- Weight of the top long bar/distribution bar
5- Length of the side bar
6- Weight of the side bar
Calculation
Length of bottom bar /main bar/Short Bar
Cutting length of the bottom =width – 2 C.C+2Bends
Cutting length of the bottom =1.870-2 (75)+2(20d)
Cutting length of the bottom =1.870-150+2(20×16)=2.360m
Number of the bottom bar
Number of the bottom bar=length/total spacing+1
Number of the bottom bar=7500/150+1=51nos
Total Length
Total Length=Numbers of the bar × Cutting Length of one bar
Total Length=51 × 2.360=1203.6m
Weight
Weight = D²/162×Total Length
Weight = 16²/162 × 1203.6=1901.98kg=1902kg
NOTE
(length of main short bar and weight of main short bar bottom and top both same)
Total weight =short bottom bar + short top bar
Total weight bottom and top bar =1902+1902=3804kg
Length of the long bar
Cutting length of the long bar= length – 2 C.C +2 bends
Cutting length of the long bar=7500-2(150)+2(20d)
Cutting length of the long bar=7500-300+2(20×16)=6.560m
Numbers of the long bar
Numbers of the long bar = width/spacing+1
Numbers of the long bar=1870/150+1=13.46=14nos
Total Length
Total Length=Numbers of the bar × Cutting Length of the one bar
Total Length= 14 × 6.560 =91.84m
Weight
Weigth of long bar=D²/162 ×Total length of the long bar
Weigth of long bar=16²/162 × 91.84=145.13=146kg
NOTE
(length of long bar and weight of long bar bottom and top both same)
Total weight of the long bar=long bar bottom + long bar top
Total weight of the long bar= 146+146=292kg
Total weight of 16mm bar in duct bank=292+1902=2194kg
Length of the side bar
Cutting Length of the side bar=length of the duct bank side -2C.C
Cutting Length of the side bar =7500-2(150)=7200=7.200m
Numbers of the side bars
Numbers of the side bars=1 left side and 1 right side=2
Total length
Total length=Number × cutting length of the one bar
Total length=2 × 7200=14400=14.400m
Weigth
Weight of the side bar = D²/162 × total length of the side bar
Weight of the side bar =12²/162 × 14.400=12.799=13KG
