A reinforced concrete beam having width of 250 mm and effective depth ...
Minimum and Maximum Tensile Reinforcement as per IS 456:2000
According to IS 456:2000, the minimum and maximum amount of tensile reinforcement for a reinforced concrete beam with a width of 250 mm and effective depth of 400 mm, reinforced with Fe 415 steel grade are as follows:
Minimum Tensile Reinforcement:
- The minimum amount of tensile reinforcement for a reinforced concrete beam is given by the expression:
As = 0.85 fy Ast / (0.87 fck x b)
Where,
- As = area of tensile reinforcement
- fy = characteristic strength of steel
- Ast = area of steel required
- fck = characteristic strength of concrete
- b = width of the beam
- Substituting the given values, we get:
As = (0.85 x 415 x 0.87 x 250 x 400) / (0.87 x 20 x 250)
- As = 204.78 mm²
- Therefore, the minimum amount of tensile reinforcement required is 205 mm² (rounding off to the nearest value).
Maximum Tensile Reinforcement:
- The maximum amount of tensile reinforcement for a reinforced concrete beam is given by the expression:
As = 0.04 Ag
Where,
- Ag = Gross area of concrete
- Substituting the given values, we get:
Ag = b x d = 250 x 400 = 1,00,000 mm²
As = 0.04 x 1,00,000 = 4000 mm²
- Therefore, the maximum amount of tensile reinforcement allowed is 4000 mm².
Hence, Option B is the correct answer.

A reinforced concrete beam having width of 250 mm and effective depth ...
Minimum tension steel
Where, Ast = Area of steel, b = breadth of beam or web in case of T beam, d = effective depth, fy = characteristic strength of reinforcement in N/mm2
Maximum tension steel
Ast max = 4 % × bd
Calculation:
Ast( minimum) = 0.85/415 *250*400 = 205 mm2
Ast (maximum)= = 0.04 × 250 × 400 = 4000 mm2
Where, Ast = Area of steel, b = breadth of beam or web in case of T beam, d = effective depth, fy = characteristic strength of reinforcement in N/mm2
Maximum tension steel
Ast max = 4 % × bd
Calculation:
Ast( minimum) = 0.85/415 *250*400 = 205 mm2
Ast (maximum)= = 0.04 × 250 × 400 = 4000 mm2
