Sometimes ribbed slabs cannot pass as one way slabs with the same thickness and in order not to create two different thicknesses. So in order to use same thickness and not have to change the structural system Of that portion or make it thicker two way ribbed slab bed are used. This is synonymous with waffle slabs.

The formwork’s assembling and the reinforcement implementation of a raft foundation stiffened by beams are two relatively strenuous procedures. A ribbed foundation can be stiffened either by beams or by walls. In the latter case the reinforcement of the foundation slab does is independent of the wall’s reinforcement.

Ribbed or waffle slab is a slab system which consists of series of parallel reinforced concrete T beams framing into reinforced concrete girders. The slab is the flange of the beam and the extended part is the web. The extended part is known as ribs. The spacing between the ribs should be in general 20-30 inch.
Waffle slab foundation - Wikipedia
A waffle slab foundation also called a ribbed slab foundation is an above-ground type of foundation used to provide load-bearing capacity in expansive rocky or hydro collapsible soils. The foundation is created by placing a series of single-use Plastic forms set directly on grade to create a grid of ribs and then monolithically pouring a post tensioned rebar or Fiber reinforced concrete ...

To develop new slabs with light weight and high rigidity as well as meet the requirements of use and facilitate construction a large-span multi-ribbed composite slab R-CS with filled lightweight blocks is proposed based on systematic research. Static tests of the bending behaviour of the four pieces of the R-CS specimens and one ordinary concrete cast-in-place slab were carried out.
Concrete slab - Wikipedia
A concrete slab is a common structural element of modern buildings consisting of a flat horizontal surface made of cast concrete. Steel-reinforced slabs typically between 100 and 500 mm thick are most often used to construct Floors and Ceiling s while thinner mud slabs may be used for exterior paving see below .In many domestic and industrial buildings a thick concrete slab supported on ...
Raft Slab vs Waffle Slab InnoHomes
The whole footing and slab system is constructed on top of the ground. The sides of the slab are made by edged Formwork and polystyrene blocks pods create the formed voids between the strip footings. When viewed from underneath the system of internal strip footings looks like a waffle – hence its called the Waffle Slab.
16 Different types of slabs in construction Where to use?
Step 3: The gaps between the bricks are called a rib. Reinforcement is provided in a form of the beam within the gap. Step 4: After placing the rib the plain steel mesh is placed on the entire slab area resting on ribs. Step 5: Now pouring of concrete is done on a slab. Where to use Hardy Slab? Hardy slab is used where temperatures are very high.
Ribbedslab - BuildingHow
The rib reinforcement follows the same rules with the beam reinforcement. However mainly as far as the stirrups are concerned the amount of placed rebars is not as large as it is in beams. Between the ribs the slab is usually reinforced with a common wire mesh.

The first step is to make a couple of design assumptions regarding the thickness of the slab and the clear spacing between ribs. The clear distance between ribs cannot be greater than 30 inches per ACI Code 318-11 Section 8.13.3 and the thickness of the slab cannot be less than one-twelfth the clear distance between ribs nor less than 2 inches per ACI Code 318-11 Section 8.13.6.1.
What Is Waffle Slab? - Iamcivilengineer
The waffle slab is also sometimes termed as ribbed slab system but you would find it interesting to know that ribbed and waffle slab are somehow two different things. When one says ribbed slab it is actually a one way spanning system with ribs where as in waffle slab the joists form a two –way system.
