Ans: One way slab is the slab having ratio of longer span to shorter span equal to or more than 1.5 . If the ratio of longer span to shorter span is equal to or less than 1.5, then such slabs are called as two way slab.
In one way slab main tensile reinforcement is placed parellel to shorter side which will be the main steel, where as in two way slab both direction required main steel.

construction joints are leave in RCC Slab one third of span.
if LY/LX>2 than we use one way slab if <2 than use two way slab.One way slab supported only two direction and two way slab supported in all four direction.
Waffle slabs are two-way spanning slabs whose beams(in two diresctions) are at very close centres whereas a ribbed slab is a one way spanning slab whose secondary beams are at very close centres, but not their primary beams.
The basic difference between one way and two way slab is load distribution which is depends on support condition and span lengths.Mainly shorter span is carring larger load than longer span.This load distribution can be calculated considering the deflection at any point is same Shorter and Longer Span.

A one way slab reinforcement supports 2 walls while a two way slab reinforcement supports 4 walls. The one way slab reinforcement only supports walls in one direction.
when l/b ratio more than or equal to 2 then slab is designed as one way and when l/b ratio is less than 2 then slab is designed as two way.
if LY/LX>2 than we use one way slab if <2 than use two way slab.One way slab supported only two direction and two way slab supported in all four direction.
Waffle slabs are two-way spanning slabs whose beams(in two diresctions) are at very close centres whereas a ribbed slab is a one way spanning slab whose secondary beams are at very close centres, but not their primary beams.
A slab push is a term given to tectonic plates that cause pressure from a down-dip motion. An example of this type of plate structure is where the Nazca plate and the South American plate meet near Peru.
The basic difference between one way and two way slab is load distribution which is depends on support condition and span lengths.Mainly shorter span is carring larger load than longer span.This load distribution can be calculated considering the deflection at any point is same Shorter and Longer Span.
difference between one- ones
when the length of the slab is more or equal to twice the breadth hence it has to be one way slab.
A one-way slab is a type of structural element in buildings that is supported mainly in one direction, either by walls or beams. It is designed to carry loads primarily in one direction, typically spanning between beams or walls running perpendicular to the slab.
