In this tutorial i have explained briefly how to calculate the quantity of steel for a two way slab
Before starting the procedure we must know how to identify a two way slab
If the ratio of longer span to the shorter of a slab is less than 2, the slab is considered as a two way slab slab
As i already told you that a one way slab is supported on beams on two opposite sides and the loads are carried along the shorter span
But in case of two way slab the supports are provided along all the dimensions since the loads are carried along both the directions.
I have illustrated this method with the help of an example
and at the end of this lecture i have shown you how to prepare the table for BBS of two way slab.

It should be noted that the spans are to be considered by excluding the width of beam from all the sides.
