Bar Bending Schedule For Footing
What is the Footing?
Foundation is that the lowest a part of the building or the civil structure that’s in direct contact with the soil that transfers masses from the structure to the soil safely. Generally, the muse are often classified into 2, particularly shallow foundation and deep foundation. A shallow foundation transfers the load to a stratum gift during a shallow depth. The deep foundation transfers the load to a deeper depth below the bottom surface.
Given data
Length of footing = 2500mm
Width of footing= 2000mm
Height of footing =300mm
Spacing=150mm
Concrete cover bottom and top=50mm
Diameter of short bar =12mm
Diameter of long bar=12mm
Now we calculate the bar bending schedule of footing
Bottom bar
Long bar
Cutting Length of long bar=total length of footing -2 concrete cover+2 bends
Bend length of long bar=15d
Bend length of long bar=15(12) =180mm
Cutting length of long bar =2500-2(50) +2(180)
Cutting length of long bar =2500-100+360=2760mm=2.760m
Number of long bar=width of footing/spacing+1
Number of long bar=2000/150+1=14.33=15Nos
Total length of long bar=cutting length of one bar x Numbers of bar
Total length of long bar=2.760 x 15=41.40m
Weight of long bar= d2/12.25xtoal length
Weight of long bar= (12)2/162.25 x 41.40
Weight of long bar= 144/162.25 x 41.40=36.74=37kg

Short bar
Cutting length of short bar= width of footing-2 concrete cover +2 bends
Bend of short bar= 15d=15(12) =180mm
Cutting length of short bar = 2000-2(50) + 2(180)
Cutting length of short bar = 2000-100+360=2260mm=2.260m
Numbers of short bar =length of footing/spacing+1
Numbers of short bar = 2500/150+1=17.66=18Nos
Total length of short bar= length of one bar x Number of short bar
Total length of short bar= 2.260 x 18=40.68m
Weight of short bar = d2/162.25 x total length of long bar
Weight of short bar = (12)2/162.25 x 40.68
Weight of short bar =144/162.25 x 40.68=36.10=37kg
WE know
Bottom of short bar =Top of short bar
Bottom of long bar = Top of long bar
Total length of short bar bottom and top bar is same
Total length of short bar of bottom bar= total length of short bar of top bar
40.68=40.68
So total length of short bar
40.68+40.68=81.36m
Weight of short bar bottom and top bar is same
Weight of short bar of bottom bar= weight of short bar of top bar
37=37
Total weight of short bar of bottom and top bar
Total length weight short bar = 37+37=74kg
Total length of long of bottom bar and top bar is same
Total length of long bar of bottom bar = total length of long bar of top bar
41.40=41.40
Total length of long bar bottom and top
41.40+41.40=82.80m
Weight of long bar of bottom and top bar is same
37=37
Total weight of long bar of bottom and top
37+37=74kg
Diameter of bottom short bar and long bar and the diameter of top short bar and long bar is same 12mm
So
The total weight of 12mm bar is= weight of bottom short and long bar +weight of top short and long bar
The total weight of 12mm bar is= 74+74=148kg
