To determine the quantity of steel rebars in a raft foundation with a volume of 18,370 m³, a common approach is to consider the reinforcement ratio, which typically ranges from 0.5% to 2% of the concrete volume. For example, at a 1% reinforcement ratio, the quantity of steel rebars would be approximately 183.7 m³ (1% of 18,370 m³). However, the exact amount can vary based on design specifications and structural requirements. Always consult with a structural engineer for precise calculations.
C 11 specification
Quantity of steel in building is calculated in many method. many engineer use to quantify the quantity of steel in a building by referring to detailed planned so they can compute the approximate weight of steel needed.
The placement of steel reinforcing is dependent on the requirements of the strength and load-bearing of the concrete. A structural engineer should be contacted in this regard.
You should see the catalog company from out of steel alloys used in steel.
The address of the Youngstown Steel Heritage Foundation is: 2261 Hubbard Rd, Youngstown, OH 44505-3156
Steel pole barns provide a strong, versatile storage or workplace. You will need a flat concrete foundation to support your pole barn.
I think that the maximum percentage of stell reinforcement in foundation is 4%
For a raft foundation, the amount of steel required is in RCC per square meter. This can be calculated using the value of 18 kilograms steel per square meter.
Steel Cannot be calculated based on cft. Load bearing capacity is required to calculate steel.
That depends on what the foundation is for and what local law says about. Technically, you don't need any steel, since there are other ways to reinforce concrete.
Bec. the steel percentage in the concrete is very low therefor we dont deduct the steel qty. from the concrete qty.the Cocrete qty. vastage is more than used steel qty.
The unit weight of rebars is typically around 7.85 kg/m³. In a reinforced concrete mix with a compressive strength of 60 MPa, the amount of reinforcement steel used is usually between 1-2% of the total volume of concrete. Therefore, the weight of rebars per cubic meter of reinforced concrete at 60 MPa would be approximately 78.5 kg/m³ to 157 kg/m³.
