Difference bw One way Two way Slab.


One – way slabs are those slabs with an aspect ratio in plan of 2:1 or greater, in which bending is primarily about the long axis
so, the slab is one way where L/B>=2

Types of one way slab
One way slab may be…
1) Solid
2) Hollow
3) Ribbed



Two way slab is a slab supported by beams on all the four sides and the loads are carried by the supports along both directions, it is known as two way slab. In two way slab, 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.
