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.

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.

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.

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.

For span more than 10 m it has to be less than 7.

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

Yovi said:   9 years ago
Why its is 12?

L/d ratio.

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