Minimum and Maximum Reinforcement in Beam

Minimum and Maximum Reinforcement in Beam is given in IS 456 2000 

The code specifies the percentage of reinforcement to be used in Beam for both Max and Min.

But in general, there are many types of reinforcement used in beam-like

In this blog, we will focus on Min Reinforcement in Tension Reinforcement and also the max reinforcement overall.

Let us assume you have a Beam 3 m in Length with its cross-section of 200 mm x 300 mm 

As_min = 0.85 bd/fy

As we Know b=200mm  d=300- Effective Cover ( but effective cover depends on bar dia also so for simplification and for better safety we take over all depth d ≈ D=300 ) and F_y = characteristic strength of steel reinforcement = 415 )

So As_min = 0.85* 200*350 / 415 = 143.3 mm2

• Max Reinforcement in  Reinforcement

 As_max = 4%bD = 4/100*200*350 = 2800 mm2
