As per IS 456 -2000 criteria for effective depth:
| Type of beam |
Span/depth When Span < 10 m |
|---|---|
| Cantilever beam | 7 |
| Simply supported | 20 |
| continuous beam | 26 |
When span > 10 m, multiply the span/depth coefficient with, \(10 \over Effective \ span\) but this factor is not multiplied for the cantilever beam.
Given that, L= 2.5 m = 2500 mm
For cantilever beam span to depth ratio = 7
then,
effective depth (d) \(= \frac{L}{\text{span to depth ratio}} \)
d= 2500/7
effective depth (d) = 357.14 mm
