Type of slab --------> Ratio of span to depth*
Simply supported and spanning in one direction --------> 30.
Continuous and spanning in one direction --------> 35.
Simply supported and spanning in two directions --------> 35.
Continuous and spanning in two directions --------> 40.
Cantilever slabs --------> 12.

1) Simply supported and spanning in one direction - 30
2) Continuous and spanning in one direction - 35
3) Simply supported and spanning in two directions - 35
4) Continuous and spanning in two directions - 40
5) Cantilever slabs - 12.

For One way Slab.

The maximum ratio of span to a depth of a cantilevered slab is 12.

The maximum ratio of span to a depth of a simply supported slab is 30.

The maximum ratio of span to a depth of a continuous slab is 35.

As par IS 456 cl 24.1.

For One way slab L/d ratio is as same as for beam.
For 2 way slab.
35 for simply supported slab.
40 for the continuous slab.

So when will be the values of the span to depth ratio for cantilever simply supported and continuous slab will be taken as 7, 20&26 respectively.

If span to effective depth is given then take 7, 20, 6.

And if span to overall depth is given then take 12, 30, 35.

L/d ratio.

Simply supported = 20.
Continuous slab = 26.
Cantilever slab = 7.

@Amit & @Bittu.

How you got this value?

In IS 456 it is not given.

Span up to 3.5m.

Depth of slab:
Fe-250.
SSB-35.
Continuous-40.

@Kirti.

These values are not for slab. They are for beams.
