Question

If X is the maximum percentage of steel that can be provided in a RC beam and Y be the minimum percentage of reinforcement that should be provided in a RC beam then value of multiplication of X and Y is ____.[Use Fe415 steel]

• A. 0.82

Answer 1

The correct option is A 0.82
$X=\text{Maximum percentage of steel}=4\%$

$Y=\text{Minimum percentage of steel}=\frac{85}{f_y}\%$

$=\frac{85}{415}=0.205\%$

So, $XY=4\times 0.205\simeq 0.82$
