Two-way slabs are rectangular reinforced-concrete slabs that are supported on all sides. The reinforcement is placed perpendicular to the sides.
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.
i want desisgn steps of two way concrete slab with an example
a slab whose length and breadth ratio is more than two is called one way slab
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.
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.
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.
1. one way slab 2. two way slab 3. flat slab 4. roof slab
The different types of slabs are; one way slab, two way slab, flat plated slab, flat slab and grid slab
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.
the ratio of Length of span / width of span = >2 or <2 Or where span of Slab is with in 3.6 m it is one way slab, and where span is more than 3.6 m it is two way slan.

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.
a slab whose length and breadth ratio is more than two is called one way slab
yes it is dangerous because the beams supporting one way slab are to be designed stronger

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.
