Definition of one way and two way slab

In this construction video tutorial, you will be familiar with the concept of one way and two way slab.

ONE WAY SLAB

In one way slab, the following properties are included :-

Support is provided by beams to one way slab in only two sides.

Primary reinforcement is arranged in only one direction toward one way slabs.

The proportion of longer span panel (L) to shorter span panel (B) is identical or more than 2. Therefore, L/B>=2

Usually all the Cantilever slabs belong to one Way slab. Chajjas and verandahs are the real instance of one way slab. In verandah the slab is stretching in the shorter direction with primary reinforcement and the allocation of reinforcement in the transverse direction.

TWO WAY SLAB

A two way slab offers the following properties :-

Support is provided by beams to the slabs in all four sides.

Primary reinforcement is set in both the direction toward two way slab.

The proportion of longer span panel (L) to shorter span panel (B) is below 2. Therefore, L/B<2.

Go through the following video presented by renowned Sami Ullah to get more details as well as sample drawing of both the slabs.
