Answer 1

Area of steel reinforcement is regulated by the following norms:

i) Minimum area of steel \(\left( {{A_{s{t_{min}}}}} \right) = \frac{{0.85}}{{{f_y}}} \times b \times d\)

Minimum area of steel is to prevent any sudden failure and to provide minimum required ductility to the section.

ii) Maximum area of steel \(\left( {{A_{s{t_{max}}}}} \right) = 4\%\) of gross area

Maximum area of steel is restricted, so as to avoid the problem of compaction while concreting.
