## Difference between the One-way slab and Two way slab.

__ONE WAY SLAB:__

1) One way slab is supported by beams in only 2 sides.

2) The ratio of longer span panel (L) to shorter span panel (B) is equal

or greater than 2. Thus, L/B >= 2.

3) Main reinforcement is provided in only one direction for one way slabs.

4) One way slabs will behave in the same manner as a support beam.

__TWO WAY SLAB:__

1) Two way slab is supported by beams in all four sides.

2) The ratio of longer span panel (L) to shorter span panel (B) is less than 2 Thus, L/B < 2.

3) Main reinforcement is provided in both the directions for two way slabs.

4) Two way slabs is evenly distributed and will reduce bending and shifting.

These are the difference between one way slab and two way slab.
