Steel is the most important material for any structural construction. So we are going to calculate how much steel quantity required for 1 cubic meter concrete. Only Concrete not used in any structural construction because the compressive strength of concrete is very good. But the tensile strength of concrete is very less and steel used in concrete to increase the tensile strength of concrete.
Steel used in concrete in the form of steel bar. Steel bar is also commonly know as rebar, rod, or reinforcement bar.
You cannot even imagine the construction of a structural member like column, beam, slab and footing without steel bar. Because even if you get these structures constructed without steel, then they are of no use, and such a structure can cause loss of life anytime.
How to Calculate Quantity of Steel in Footing, column, slab, and beam
Since columns, beams, slabs, and footing are the supporting structures of any building. Therefore steel should be used in all these structures along with concrete. Because all these structures handle the weight of the building, and through them, the entire weight of the building is transferred to the ground.
Steel must be used in columns, slabs, beams, and footings and the same is determined by the Thumb rule. So in this article, we will learn how to calculate steel quantity in Slab/ footing/ column/ beam.
As a thumb rule, different amounts of steel required for columns, slabs, beams, and footings.
- According to the thumb rule, 2.5% steel is required for the total weight of the concrete for the column.
- According to the thumb rule, 1% steel is required for the total weight of the concrete for the slab.
- According to the thumb rule, 0.5% steel is required for the total weight of the concrete for the footing.
- According to the thumb rule, 2% steel is required for the total weight of the concrete for the beam.
How to calculate the quantity of steel in column
How much steel required for the column: To calculate the amount of steel in the column, we need to know the length, width, and thickness of the column. And we should know the density of steel.
The density of Steel = 7850 kg/m3.
According to the thumb rule, 2.5% steel required for the total weight of the concrete for the column.
Assume the length of the column = 5 m.
width of the column = 0.609 m.
The thickness of the column = 0.609 m.
Now, first of all, we have to calculate the volume of concrete = length × width × thickness.
= 5 × 0.609 × 0.609 = 1.854 m3.
Required steel quantity = steel quantity percentage × density of steel × volume of concrete
= (2.5/100) × 7850 × 1.854
= 363.847 kg.
How to calculate the quantity of steel in Slab
Steel calculation for the slab: To calculate the amount of steel in the slab, we need to know the length, width, and thickness of the column. And we should know the density of steel.
The density of Steel = 7850 kg/m3.
According to the thumb rule, 1% steel required for the total weight of the concrete for the slab.
Assume the length of the slab = 8 m.
width of the slab = 5 m.
The thickness of the slab = 0.10 m.
Now, first of all, we have to calculate the volume of concrete = length × width × thickness.
= 8 × 5 × 0.10 = 4 m3.
Steel quantity for slab = steel quantity percentage × density of steel × volume of concrete
= (1/100) × 7850 × 4
= 314 kg.
How to calculate the quantity of steel in footing
Steel calculation for the footing: To calculate the amount of steel in the footing, we need to know the length, width, and thickness of the column. And we should know the density of steel.
The density of Steel = 7850 kg/m3.
According to the thumb rule, 0.5% steel required for the total weight of the concrete for the slab.
Assume the length of the footig = 2 m.
width of the footing = 2 m.
The thickness of the footing = 0.30 m.
Now, first of all, we have to calculate the volume of concrete = length × width × thickness.
= 2 × 2 × 0.30 = 1.2 m3.
Steel quantity for footing = steel quantity percentage × density of steel × volume of concrete
= (0.5/100) × 7850 × 1.2
= 47.1 kg.
How to calculate the quantity of steel in beam
Steel calculation for the beam: To calculate the amount of steel in the beam, we need to know the length, width, and thickness of the column. And we should know the density of steel.
The density of Steel = 7850 kg/m3.
According to the thumb rule, 2% steel required for the total weight of the concrete for the slab.
Assume the length of the beam = 5 m.
width of the beam = 0.30m.
The thickness of the beam = 0.30 m.
Now, first of all, we have to calculate the volume of concrete = length × width × thickness.
= 5 × 0.30 × 0.30 = 0.45 m3.
Steel quantity for beam = steel quantity percentage × density of steel × volume of concrete
= (2/100) × 7850 × 0.45
= 70.65 kg.
