What is difference between one way slab and two way slab and know about one way slab and two way slab,in this topic we know about difference between one way slab and two way slab.
Let us discuss what is one way slab and two way slab. In structural system slab have heavy structure made of concrete resist generally gravity load acting on brick wall and beam ,from the beam to the column and from column to the footing of foundation and foundation to the bed of soil.
In civil construction work slab is given over roof of building, Bridge ,floor, reck chhaja and baramada. Slab is horizontal flat surface which is supported by brick wall and beam and column.
What is one way slab?
● one way slab :- the slab which is supported by beams on two opposite sides only in single direction that is one way slab. That’s why one way slab bend in one direction and load acting on it that is dead load and live load distributed only in two opposite sides in single direction.
If the ratio of longer span and shorter span is equal or greater than 2 then we should adopted one way slab. And it will bend in one direction that is shorter direction of Span.
Mostly one way slab have two parallel beam which carry load acting on it by the slab.
reinforcement used in one way slab
As we know there is a two types of bar used in slab one is main bar that is also known as crank bar and second one is distribution bar.
In one way slab main bar that is crank bar used only in one direction of shorter span in bottom of slab and cross bar that is distribution bar is straight bar putting over main bar in longer span.
What is two way rcc slab?
● two way slab :- in two way slab it is supported by beam on all four sides and load carried in both direction. And distribute the load in all four sides in equal manner.
That’s why in two way slab it’s bend in both direction and resistance is provided from all four sides of beam to withstand with gravitational load acting on it by load and live load.
In two way slab ratio of longer span and shorter span is less than 2 then we adopted two way slab.
reinforcement used in one way slab
As we know there is a two types of bar used in slab one is main bar that is also known as crank bar and second one is distribution bar.
In one way slab main bar that is crank bar used only in one direction of shorter span in bottom of slab and cross bar that is distribution bar is straight bar putting over main bar in longer span.
reinforcement used in two way rcc slab
In two way slab main bar that is crank bar used in bottom of slab in both direction of longer span as well as shorter span. And that is cross bar used in top of slab that is straight bar used over main bar.

What is difference between one way slab and two way slab
1) one way slab supported by beam on the two opposite sides only
In two way slab it is supported by beam on all four sides
2) in one way slab main bar that is crank bar used only in shorter span in single direction
In two way slab main bar that is crank bar used in both longer and shorter span of slab in both direction.
3) in one way slab load are carried into one opposite direction only
But in two way slab load are carry into all four sides
4) in one way slab ratio of longer span and shorter span is equal or greater than 2
in two way slab ratio of longer span and shorter span is less than 2
