Unit weight of steel bars according to their diameter?
Calculation for weight of steel. Volume of Steel Rod(Vs)= (pi*d*d)/4*l.where pi= 3.14 d Diameter of bra= 8 mm in this case l length of bar = 1 m so, Volume of steel = ((3.14*0.008*0.008)/4)*1 =0.00005024 m3 Weight of steel = volume of steel * unit weight of steel Unit weight of steel = 7850 kg/m3 Weight of steel = 0.00005024* 7850 = 0.394 kg/m
The calculation of quantity of steel in a beam is steel quantity is equal to 1 percent of concrete quantity. Another way to measure it is steel quantity is found by multiplying number of bars by length of one bar by unit weight of steel where the unit weight of steel is d up to 2 divided by 162, d minus is the diameter of the bar.
The unit weight of steel is 7850kg per cubic meter, so the unit weight of different bars can be calculated by multiplying the volume of 1m length of bar with the unit weight of steel. It can also be calculated simply by dividing the square of the diameter of bar in mm by 162. Diameter of bar unit weight calculation. 8 0.395kg/m w=8x8/162 10 0.617kg/m w=10x10/162 12 0.889kg/m w=12x12/162 16 1.580kg/m w=16x16/162 20 2.469kg/m w=20x20/162…
