How to calculate the weight of the steel bar, how to calculate the weight of the steel bar

The theoretical weight of a rebar with a diameter d is d 2 100*

2 is squared, which is the theoretical weight of 10 steel bars with a diameter, you only need to remember the theoretical weight of 10 steel bars!

Diameter 12 and below retains three decimal places; Two decimal places are kept for diameters above 12; Rounding up to 6 at the time of reservation!

Here are the diameters per meter of kilogram weight 6 = 8 = 10 = 12 = 14 = 18 = 16 = 20 = 22 = etc. (there are others, if you don't count, you multiply the base area by the total length and then multiply by the ton, the specific gravity of the iron.

The weight of the bars per meter is equal to the square of the diameter of the bars multiplied by the square.

The unit of diameter is millimeters.

The weight is measured in kilograms.

If possible, you can check the reinforcement weight table directly.

The weight per meter of rebar with diameter * diameter * 8mm is 8*8* =. The quality of the country has regulations that can be checked.

In parentheses are the diameter of the reinforcement: (6): 8 ): ).

22):: Method 2: d is the diameter of the steel bar.

Weigh the weight of the meter.

Multiply by the square of the diameter (the unit of diameter is millimeters, but the result is kg m).

According to the specific gravity of the reinforcement.

The specific gravity of the reinforcement cross-sectional area * 7850

The length is multiplied by the theoretical weight of the rebar.

How to calculate the weight of steel bars! Hello, I am glad to answer for you<> the calculation method of the weight of the rebar is: in fact, the calculation of the weight of the rebar is very easy to remember, just remember it.

The weight of one meter of steel bar (kg) = the size of the steel bar (mm cm) The size of the steel bar (mm inside) The size of the steel bar The size of the steel bar = The weight of the steel bar one meter No matter what steel bar, round steel rebar, such as slag Qing is the size of the steel bar The size of the steel bar is universal. Although round steel and rebar look different, the theoretical total amount is the same, both of which contain 12) or less and 28 (including 28) steel bars are generally taken to three decimal places, and 14 to 25 steel bars are taken to two decimal places after the same beam book. Hope mine can help you <>

Do you have any other questions?

The diameter of the rebar is 8 per meter of weight; The diameter of the rebar is 10 per meter of weight; The diameter of the rebar is 12 per meter of weight; The diameter of the rebar is 16 per meter of weight; The diameter of the rebar is 18 per meter of weight; The diameter of the rebar is 20 per meter of weight; The diameter of the rebar is 22 per meter of weight; The diameter of the rebar is 25 per meter of weight.

The weight of the reinforcement per meter (kg) = the diameter of the reinforcement (mm) The diameter of the reinforcement (mm), that is, the weight of the reinforcement is proportional to the square of the diameter. At the same time, the theoretical weight of the reinforcement (kg) cross-sectional area.

Reinforcement performance: 1. The process performance of reinforcement includes many items, and different requirements can be put forward for the characteristics of different products, such as bending and reverse bending (reverse bending) tests for ordinary steel bars, and repeated bending, torsion and winding tests for some prestressed steels.

2. The form of all these tests simulates the processing method that may be involved in the actual use of the material to varying degrees, such as ordinary steel bars need to be hooked or bent to form, and prestressed steel wires sometimes need to be wound, etc., and the purpose is to assess the ultimate bearing capacity of the materials for these specific plastic deformations.

3. Therefore, the process performance is also a plasticity requirement for the material, and the key beat Chang is the same as the above ductility (elongation) requirements.

4. However, compared with the unidirectional stress state during tensile, the stress state of the process performance test is much more complex, and the deformation type and size of the sample are different in all directions (axial and radial), and the microstructure, grain size, and content of harmful residual elements of the steel, especially any defects such as cracks and inclusions that affect the continuous deformation inside and on the surface may affect and lead to the failure of the test.

5. So in a sense, for the assessment of the quality of steel, it can be said that the process performance test is more stringent.

6. In addition, the reverse bending test of steel bar is essentially a strain aging sensitivity test, which is because molten steel generally contains a certain amount of free nitrogen (N), also known as residual nitrogen, and when the content is too high, it can lead to embrittlement of steel at room temperature after plastic deformation.

Weight of rebar per meter (kg) Diameter of rebar (mm) Diameter of rebar (mm).

The weight of the rebar in kg

First, find the theoretical weight (specific gravity) of the reinforcement = in kg m

The weight of the reinforcement kg = l (m) * specific gravity (kg m).

Theoretical weight table of rebar:

Angle steel: weight per meter = side width + side width - side thickness) * edge thickness.

Round bar: weight per meter = diameter * diameter (rebar and round bar are the same) flat bar: weight per meter = thickness * side width.

Pipe: weight per meter = wall thickness * (outer diameter - wall thickness).

Plates: weight per meter = thickness * area.

Brass tube: weight per meter = wall thickness * (outer diameter - wall thickness).

Copper tube: weight per meter = wall thickness * (outer diameter - wall thickness).

Aluminum pattern plate: weight per square meter = thickness.

Specific gravity of non-ferrous metals: copper plate, brass plate, zinc plate, lead plate.

The calculation formula for non-ferrous metal sheet is: weight per square meter = specific gravity * thickness.

How to calculate the weight of various specifications of rebar, and is there a standard? How much?

It is a round 10 rebar per meter weight. The weight of the rebar is proportional to the square of the diameter (radius).

g m = weight per meter (kg) diameter of steel bar (mm) diameter of steel bar (mm) In fact, it is very simple to remember the weight of steel bars commonly used in construction projects: 6 kg 8 10 12 14 16 18 24

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

18=2kg

20=22=3kg

40 = Simplified formula for calculating the theoretical weight of steel.

Flat bars, steel plates, steel strips w width and thickness.

Square steel w side length 2

Round steel, wire rod, steel wire w straight and sharp state diameter Qiao Kuan Jing 2

Steel pipe w wall thickness (outer diameter - wall thickness).

Equilateral angle steel w side filial piety (2 sides wide - side thickness).

Unequal angle steel w side thickness (long side width + short side width - side thickness) I-beam w waist thickness [height + f (leg width - waist thickness)].

Channel w waist thickness [height + e (leg width - waist thickness)].

Weight per metre (kg) of any isometric balance trouser grade reinforcement = square of diameter.

For example: 25 steel bars 5 meters weight silver Jane.

You can use the formula, rebar diameter * rebar diameter = weight per meter of rebar for that diameter.

The weight of the rebar = the length of the rebar (in meters) multiplied by the weight of the rebar per meter Weight per meter = unit kg m

Expanded Yu Xinzhan Information:1. The weight of the steel bar = the length of the steel bar (in meters) multiplied by the weight of the steel bar per meter. The length of the steel bar can be obtained by turning the sample, and the weight of the steel bar per meter can be destroyed to check the relevant information.

2. The weight of the steel bar per meter = diameter * diameter.

3. You can check the construction manual, which has a detailed **, and you can also check the hardware manual.

4. For commonly used, there are the following data, which should be memorized: 6 = 8 = 10 = 12 = 14 = 16 = 18 = 20 = 22 = 25 = 28 =
