# DIFFERENCE BETWEEN ONE WAY SLAB AND TWO WAY SLAB

## ONE WAY SLAB:

One way slab is a slab which is supported by beams on the two opposite sides to carry the load along one direction.

The ratio of longer span to shorter span is equal or greater than 2 , considered as One way slab because this slab will bend in one direction i.e in the direction along its shorter span

• 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.
• They are designed to transfer their general loads to the opposite support walls. The actual structural support of a one way slab is found on the shortest spans.

### Two Way Slab:

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

In two way slab, the ratio of longer span to shorter span is less than 2. In two way slabs,Â loadÂ will be carried in both the directions. So, main reinforcement is provided in both direction for two way slabs.

• The transfer of the load is on all of the walls, all four become support walls. The supports will run perpendicular to each other.
• The actual structural support of a two way slab is found on two directions or on all four spans
