A flat plate system will be.
Waffle floor slab design.
As a result waffle slabs has been widely used for office buildings hotels auditoriums vestibules theatre halls show rooms of shops where columns free space is often the main requiremen.
The extended part is known as ribs.
The slab is the flange of the beam and the extended part is the web.
Slab depths typically vary from 75 to 125 mm and rib widths from 125 to 200 mm.
The name waffle comes from the grid pattern created by the reinforcing ribs.
The spacing between the ribs should be in general 20 30 inch.
Rib spacing of 600 to 1500 mm can be used.
We would like to show you a description here but the site won t allow us.
The main objective of this project work is to come up with a design of waffle slab.
A waffle slab or two way joist slab is a concrete slab made of reinforced concrete with concrete ribs running in two directions on its underside.
Ribbed or waffle slab is a slab system which consists of series of parallel reinforced concrete t beams framing into reinforced concrete girders.
