If the % age of tension steel is more than 4 than the failure of concrete occur early than the failure of steel. Thus if this happens the failure occurs immediately as the concrete has no yield point it collapse immediately which is not safe. Thus Ast should not be more than 4%.

@Mukesh.
You can calculate minimum tension requirement in fe500 by the formula given by the code (Cl.26.5.1).
i.e; (Ast)min.= .85bd/fy.

Because it's uneconomical.

According is 456:2000 maximum area of tension reinforcement in beams shall not exceed 4% of total gross cross sectional area.

Minimum area of steel 0.17 and max 4 per.

According to ACI the minimum reinforcement should 18% for 60 grade steel and 0.2 for 40 grade steel.

According to the clause 26.5.1.1 b) maximum reinforcement-the maximum area of tension reinforcement shall not exceeds 0.04 bD.
So, 0.04 bD/bD*100 = 4%.
So, 0.04 bD/bD*100 = 4%.

Area of steel- m time of concrete.

If tensile reinforcement of beam should exceed 4% of total gross area then some crack will be developed in concrete.
