| The effective depth in a singly reinforced concrete beam is defined as the distance between the compression edge.
A. To the centre of compression steel
B. To the centre of tension steel
C. To the bottom edge of the beam
D. To the neutral axis of the beam

Right Answer is: B
SOLUTION
Concept:
- Effective depth (d): It is the distance between extreme compression fibres to the centroid of tension reinforcement of the beam section.
- Effective cover for compression face (d’): It is the distance between extreme compression fibres to the centroid of compression reinforcement of the beam section. It is applicable for doubly reinforced beam or columns.
- Actual or total depth (D): It is the distance between extreme compression fiber to the bottom edge of the beam section (or soffit of beam).
- Depth of neutral axis (xu): It is the distance between extreme compression fibres to the depth of neutral axis of the beam section.
- A diagram indicating all the different depths is shown below:
