"What is the main Difference Between ONE Way and Two Way Slab in Civil Engineering"

  

One Way Slab

One way Slab under load

One way slab is supported on two opposite side only thus Bending in One direction. Total load is carried in the direction perpendicular to the supporting beam. If a slab is supported on all the four sides but the ratio of longer span (l) to shorten span (b)  is greater than 2, then the slab will be considered as one way slab. Because due to the huge difference in lengths, load is not transferred to the shorter beams. Main reinforcement is provided in only one direction for one way slabs. 

Ly/Lx > 2 

or 

Ly/Lx > 0.5

above both criteria are  Slandered

Two Way Slab

Two way slab

Two way slabs are the slabs that are supported on four sides and the ratio of longer span (l) to shorter span (b) is less than 2. In two way slabs, load will be carried in both the directions. So, main reinforcement is provided in both direction for two way slabs.Bending is also in Both Direction.

Ly/Lx < 2 

or 

Ly/Lx < 0.5
