Simple way
to find the weight of reinforcing bar:
The density of steel is 7850 kg/m³.
Now let say you want weight per m. then what will be the formulation? Check this
out.
6165.375 (kg/m³) x d² (m²)
= mass per m. (eq.

to find the weight of reinforcing bar:
The density of steel is 7850 kg/m³.
Now let say you want weight per m. then what will be the formulation? Check this
out.
7850(kg/m³) x [pi()/4 x d² ](m²)=
mass of the bar per m. (eq. 1)
Now resolving this we get 7850 x pi()/4 = 6165.375 right? Putting this
into eq. 1
6165.375 (kg/m³) x d² (m²)
= mass per m. (eq.
2)
What can be bar diameter? Let say
10mm, 12mm. . . we are used to mm format bar diameters, right? So, let us make
formulation to eq. 2 for inputting bar dia as mm.
10mm, 12mm. . . we are used to mm format bar diameters, right? So, let us make
formulation to eq. 2 for inputting bar dia as mm.
1m = 1000mm. => 6165.375 x 10^-6
= 1/162.196
= 1/162.196
Hence, mass
per m of bar = d² (mm²)/162.196.
per m of bar = d² (mm²)/162.196.
Now if you
want to get mass per feet, then use this relation 1m = 3.281 feet
want to get mass per feet, then use this relation 1m = 3.281 feet
Therefore mass
of bar per feet = d² (mm²)/(162.196 x 3.281) = d² (mm²)/532.139.
of bar per feet = d² (mm²)/(162.196 x 3.281) = d² (mm²)/532.139.
So now
onwards, please don’t bother to use d²/162.2 for finding mass of reinforcement.
Enjoy.
