Do you know the calculation methods of steel and steel plate? Bian Xiao, who is building the Engineering Education Network, has collected some formulas for calculating steel and steel plates, and shared them with friends of cost, hoping to be helpful to your work and study.

First, the basic knowledge of computing

1 m =3.28 1 ft.

1 inch =25.4 mm

1 lb = 0.4536kg.

1 kg force =9.8 1 Newton

1 lbf =4.45 newtons

1 MPa = 145. 16 1 pound/square inch.

Specific gravity (density) of steel: 7.8g/cm3

Specific gravity * (density) of stainless steel: 7.78g/cm3.

Specific gravity (density) of aluminum: 2.7g/cm3.

Specific gravity (density) of zinc: 7.05g/cm3.

Second, the theoretical weight calculation formula of various steels

Third, the calculation method of steel plate weight

Note: In the formula, the unit of length is meters, the unit of area is square meters, and the rest units are millimeters.

1) steel pipe weight (kg)=0.006 17* diameter * diameter * length;

2) Square steel weight (kg)=0.00785* side width * side width * length;

3) Hexagon weight (kg)=0.0068* opposite width * opposite width * length;

4) octagonal steel weight (kg)=0.0065* opposite width * opposite width * length;

5) Steel bar weight (kg)=0.006 17* calculated diameter * calculated diameter * length.

6) Angular weight (kg)=0.00785* (width+width-thickness) * thickness * length;

7) weight of flat steel (kg)=0.0075* thickness * side width * length;

8) Steel pipe weight (kg)=0.02466* wall thickness * (outside diameter-wall thickness) * length;

9) Steel plate weight (kg)=7.85* thickness * area;

10) weight of round copper bar (kg)=0.00698* diameter * diameter * length;

1 1) weight of round brass bar (kg)=0.00668* diameter * diameter * length;

12) weight of round aluminum bar (kg)=0.0022* diameter * diameter * length;

13) weight of square copper bar (kg)=0.0089* side width * side width * length;

14) weight of square brass bar (kg)=0.0085* side width * side width * prism;

15) weight of square aluminum bar (kg)=0.0028* side width * side width * length;

16) weight of hexagonal copper bar (kg)=0.0077* opposite width * opposite width * length;

17) weight of hexagonal brass bar (kg)=0.00736* side width * opposite side width * length;

18) weight of hexagonal aluminum bar (kg)=0.00242* opposite width * opposite width * length;

19) copper plate weight (kg)=0.0089* thickness * width * length;

20) Weight of brass plate (kg)=0.0085* thickness * width * length;

2 1) aluminum plate weight (kg)=0.00 17 1* thickness * width * length;

22) weight of round copper tube (kg)=0.028* wall thickness * (outside diameter-wall thickness) * length;

23) weight of round copper tube (kg)=0.0267* wall thickness * (outer diameter-wall thickness) * length;

24) weight of round steel (kg)=0.006 17* diameter * diameter * length;

25) weight of round aluminum pipe (kg)=0.00879* wall thickness * (outside diameter-wall thickness) * length;

26) weight of stainless steel pipe (kg/m)=0.0249 1* wall thickness * (outer diameter-wall thickness)

27) Weight of angle steel per meter =0.00785* (width+width-thickness) * thickness.

There are so many calculation methods for steel and steel plates today. Have you learned everything?

Construction engineering education network 20 19 first-class cost engineer course has been opened! Based on years of successful counseling experience, starting from the actual needs of students, combined with the rules, key points and difficulties of the first-level cost engineer examination and advanced teaching concepts, the online school has newly launched a number of personalized counseling classes in the 20 19 first-level cost engineer value enhancement class, efficient forensics class, worry-free customs clearance class and 84 face-to-face training camp, each of which is carefully designed for candidates.
