As per IS 456 : 2000,
a) Minimum % tension reinforcement:
\({{\rm{p}}_{{\rm{min}}}} = \frac{{0.85}}{{{{\rm{f}}_{\rm{y}}}}} \times 100\% \)
b) Maximum % tension reinforcement:
pmax = 4%of gross area
Calculation:
Minimum percentage of steel (for Fe500)
\({{\rm{p}}_{{\rm{min}}}} = \frac{{0.85}}{{415}} \times 100\%\)
= 0.2%
∴ Minimum percentage of steel (for Fe415) is 0.2Last updated on May 28, 2025
