L/d ratio.

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

Why its is 12?

Ram said:   9 years ago
Its the case of span more than 10 m.

Venkat Ramana said:   9 years ago
For span more than 10 m it has to be less than 7.

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.

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.

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.

@Kirti.

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

@Sanju.

It's for slab.
