Dear Fried,

I want ot clarify the above one

Let us assume 8 mm dia of bar for 1 running metre lenth ok, pls convert the dia of bar  into metre

Formula will be  (22 x 0.008 x 0.008 x 7850 x 1)/4 = 0.394 kg/m3

Short method  = d x d / 162

8 x  8 = 64/162 = 0.395 kg/m3

is this ok

wt of steel bars used RCC will be = dxd /162     as per johnsi rani
weight of steel per meter length=d x d 162.2      as per diljit singh chaudhary

out of above both which is wrong ?

normally we can used a rule to find out wt of steel is = Area x thickness x density of Steel
If it is RHS means Area x thichness and multiplied by 7850 kg/m3
The short method to find the wt of steel bars used RCC will be = dxd /162

Hope this ok for you,

weight of steel per meter length=d x d 162.2   where d=dia. of steel in mm .....and weight will be in kg....

HI,
I can only answer your first question i.e how to calculate the weight of steel

. For this you must know the dimensions of steel bar. then you can easily find out the volume of the steel bar by π* r2h,if it is circular. the density of steel is 7850 kg/m^3.

as  density = mass/ volume
so mass = density * volume
by putting the values, we get the mass of steel.

Regards,
