What makes one-way slab and two-way slab different from each other

The slab is a flat and smooth surface on the ground or over the ground supported by two-member on two or all sides is known as the slab. Slab connect almost all member like a beam, column, stairs, etc to provide a movable environment for the people on it. The slab may be of different shapes like rectangular, square, triangular, etc. but according to design it is categorized into two types, they are one-way slab and two-way slab.

Hey, guys in this article l have described the difference between slabs as many students had asked with me for a month through a comment to make an article on differences between the one-way slab and two-way slab so, l have brought this article today for you.

So let’s start,

it is supported on the column, beam, wall, etc with reinforcement or without reinforcement for safe locomotion from one place to another place.

Now let us move towards the differents between one-way slab and two-way slab

SNOne way SlabTwo way Slab
1)In one way slab two beams are only used to support slab. It means the slab are supported by four two beam.In two way slab four beams are used to support slab. It means the slab are supported by four beam.
2)In one way slab the ratio of length to width of slab is always equal or greater than two.In two way slab the ratio of length to width of slab is always less than two.
3)Main reinforcement is provided in only one direction is one way slab.
See in this picture.
Main reinforcement is provided in both direction is two way slab.
See in this picture.
4)There are distribution rod perpendicular to main rods.There are no distribution rod perpendicular to main rods.
5)Main rods has provided only in one direction of the slab.The main rods has provided in two direction of the slab.
6)Loads are transferred though two direction.Loads are transferred though all four direction of slab.
7)Bent up bars are provided in one direction.Bent up bars are provided in two direction.
8)It have high possibilities of generating cracks during earthquake.It has low possibilities of generating cracks in earthquake.

See on the left side of the picture, this is a one-way slab because there are two-beam only.

In the same way, See on the right side of the picture, this is a two-way slab because it contains four-beam.

So, I hope this article on “Different between the one-way slab and two-way slab” remains helpful for you. Further, if you have any question then please comment below.
