There are two kinds of depth which can be considered in a design
1 Clear depth = D – d
2 Effective depth
In general case the effective depth will be D – d – (phi/2).
where D = total depth
d= clear cover (just exposing main rebars)
phi= diameter of main bar.
Because of the small value sometimes designer ignore phi for small rebar dia. But if the dia of the phi is more (>10mm) then it should be taken into consideration .
