What is the effective depth in beams or slabs? How is it calculated?

Effective depth is the distance between extreme compression fiber to the centroid of tension reinforcement in a section under flexure. If h is the total depth of section, c the clear cover to outer reinforcement, d” and d’ be the diameters of tension bar and shear links respectively, the effective depth of section for flexure design of the section can be calculated as h – c – d’ – (d”/2), which will be the C.G of tension reinforcement.
