Reinforced Cement Concrete

Calculation of Area of Tensile Steel

As per IS 456...

Question

As per IS 456:2000, the minimum percentage of tension reinforcement (up to two-decimal places) required in reinforced-concrete beams of rectangular cross-section (considering effective depth in the calculation of area) using Fe500 grade steel is ______.
0.17

Open in App

Solution

The correct option is A 0.17
$\frac{A s t}{b d} = \frac{0.85}{f_{y}}$

$\frac{A s t}{b d} = \frac{0.85}{500}$

Percentage $= \frac{A_{s t}}{b d} \times 100$

$= \frac{0.85}{500} \times 100$

= 0.17
