Waffle Floor Slab Design
The overall depth of the floor typically varies from 300 to 600 mm with overall spans of up to 15 m if reinforced longer if post tensioned.
Waffle floor slab design. 1 2 objectives of study. Ribbed or waffle slab is a slab system which consists of series of parallel reinforced concrete t beams framing into reinforced concrete girders. The spacing between the ribs should be in general 20 30 inch. A flat plate system will be.
The name waffle comes from the grid pattern created by the reinforcing ribs. The lateral loads are independently resisted by shear walls. 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. Slab depths typically vary from 75 to 125 mm and rib widths from 125 to 200 mm.
We would like to show you a description here but the site won t allow us. 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. The slab is the flange of the beam and the extended part is the web. The extended part is known as ribs.
The main objective of this project work is to come up with a design of waffle slab.
