Effective Depth (d)

Summary

The effective depth (d) of a reinforced concrete floor slab is the distance from the compression face to the centre of the tensile steel when an element is subjected to a bending moment.

Technical Information

In calculations regarding concrete slabs, the effective depth is important as it is used to calculate the required level of reinforcement for an element of a certain thickness to resist a certain bending moment.

The effective depth is also used to find the critical punching perimeter and is used in the shear capacity calculations. In this instance the effective depth of a slab with fibre reinforcement or no reinforcement should be taken as 0.75h, where h is the overall depth.
