0.6 17 is the reinforcement weight per meter of circle 10. The weight of steel bars is proportional to the square of the diameter (radius).

G=0.6 17*D*D/ 100

Weight per meter (kg) = rebar diameter (mm)× rebar diameter (mm)×0.006 17.

In fact, it is very simple to remember the weight of steel bars commonly used in construction projects: φ 6 = 0.222kgφ 6.5 = 0.26kgφ 8 = 0.395kg φ10 = 0.617 kgφ12 = 0.888kgφ14 =/kloc. 438+08 = 2.0kgφ24 = 2.47kgφ22 = 2.98kgφ25 = 3.85kgφ28 = 4.837kg ............

Steel bars below φ 12 (including 12) and φ 28 (including 28) generally take three decimal places, and steel bars from φ 14 to φ 25 generally take two decimal places.

φ 6 = 0.222kg.

φ8 = 0.395kg

φ 10 = 0.6 17kg

φ12 = 0.888kg.

φ 14 = 1.2 1kg

φ 16 = 1.58kg

φ 18 = 2kg

φ 20 = 2.47kg.

22 = 3Kg

φ 25 = 3.86kg.

I have an empirical formula. Just calculate your own table. You can also buy a book with a watch, which is also very convenient to use.

A simple formula for calculating the theoretical weight of steel

Material Name Theoretical Weight W (kg/m)

Flat steel, steel plate and steel strip w = 0.00785× width× thickness

Square steel w = 0.00785× side length 2

Round steel, steel wire and steel wire w = 0.006 17× diameter 2.

Steel pipe w = 0.02466× wall thickness (outside diameter-wall thickness)

Equiangular W = 0.00785× side thickness (2 side width-side thickness)

Unequal angle steel w = 0.00785× side thickness (long side width+short side width-side thickness)

I-beam w = 0.00785× waist thickness [height +f (leg width-waist thickness)]

Channel steel w = 0.00785× waist thickness [height +e (leg width-waist thickness)]

comment

The exact calculation formulas of 1, angle steel, I-beam and channel steel are very complicated, so the approximate values are calculated by table simplification.

2.f value: 3.34 for general model and A model, 2.65 for B model and 2.26 for C model. ..

3.e value: 3.26 for general model and A model, 2.44 for B model and 2.24 for C model. ..
