What Is Slab?
The slab is a crucial structural component, which is used to form smooth or horizontal surfaces, like floors, roofs decks, ceilings, and decks.
A slab typically has a certain thickness and is supported by various structural elements such as RCC columns RCC beams and walls or the surface of the ground.
The slab is composed of cement concrete. The the top and bottom surfaces being close to each other or nearly so. The thickness of a concrete slab is tiny in comparison to its span or length.
There are two main kinds of slabs utilized in construction: 2-way and one-way slabs. In this post, we'll examine the differences between One Way Slab and Two Way Slab.

What Is a One-Way Slab?
In accordance with IS 456:2000 the slab is known as a one-way slab when the ratio of the longer span(L) and shorter span(B) that is (L/B) higher than 2. In the general practice One-way slabs are supported by two walls or beams.
A flat, evenly loaded slab is deformed into the form of a circular surface, where the curvature and consequently the bending moment is developed within a single direction. this type of slab is referred to for its one-way slab.
One-way slabs function as a beam that is shallow with a wide length. The slabs supporting on all four sides act as one-way slabs when the ratio of longer span (ly) relative to the smaller width (lx) is higher than.
Verandah is the most apt example of a one-way slab. The slab is traversing in a shorter direction, with the main reinforcement and reinforcement is distributed to the reverse direction.
What Is Two Way Slab?
Two-way slabs are supported by all four sides. In this slab the load will be transferred in both directions, resulting in the main reinforcement will be available in both directions for slabs.
The two-way slab the ratio of the longer span to shorter spans is less than two, which is able to carry the weight by flexing in 2 perpendicular directions.
in the case of the two-way slab, the shorter span and the longer span deflects into the shape of a dish or saucer.
In this type of slab shear forces as well as large moments are created near the column. Thus, the thicknesses and slabs' thicknesses are closer to the column.
These slabs are mostly used for the floors of multistoried structures.

What Is Flat Slab?
The flat Slab is a cost-effective slab that is supported by concrete columns instead of using a beam.
Flat slabs can be used for a broad array of possibilities. Many hotels, industrial structures and parking garages, warehouses and ramps and tall buildings are the main components that can be utilized.
It's purpose is providing a lot of light to pass through beams' depth by raising the floor's height.
One Way Vs Two Way Slab
The primary distinction in One Way and Two Way Slabs in that the bending is only present in one direction i.e. it is the direction that's shorter in One Way Slab however the Two Way Slab the bending moment is present throughout both directions i.e. shorter and more.
The deflected shape is cylindrical in one direction and the country form of the deflected structure looks similar to a saucer or dish in the Two Way Slab.
