### DIFFERENCE BETWEEN ONE WAY SLAB AND TWO WAY SLAB.

Slab

The slab is the horizontal structural element which takes the various loads acting on it and transfer that loads on to beams around it. The slab may be simply supported, continuous, or cantilever types. The slab is a horizontal element of the building generally made of concrete.

Slabs are categorized into two types:

1. One Way Slab

2. Two Way Slab

1. One Way Slab:

The slab which have supported by beams from only two opposite site to take a load is known as one way slab. The ratio of longer span (x) to shorter span (y) is equal or greater than 2, considered as One way slab because this slab will bend in one direction ( the direction parallel to longer span or direction perpendicular to shorter span )

one way slab and two way slab equation

Cause of the apparently difference in lengths, the load is transferred through the shorter span to beam. Main reinforcement is provided in shorter span and distribution reinforcement in a longer span.

2. Two Way Slab:

The slab which is supported by beams from its every sides to take the load 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, the load will be carried in both the directions. So, the main reinforcement is provided in both directions for two way slabs. But the heavy reinforcement or less distanced reinforcement is laid in shorter span and remaining on longer span.
