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. In one way slab the ratio of Longer span(l) to Shorter span(b) is greater than or equal to 2,
ie.., Longer Span(l) / Shorter Span(b)  ≥ 2.

 Verandah slab is a type of one way slab, where the slab is spanning in the shorter direction with main reinforcement and the distribution of reinforcement in the transverse direction.

 TWO WAY SLAB:
     When a reinforced concrete slab is 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.
 ie.., Longer span(l) / Shorter span(b) < 2.    

 This type of slabs are mostly used in the floor of multi-storey buildings.
