In this article, we want to talk About What is Waffle Slab . Join 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 name waffle comes from the grid pattern created by the reinforcing ribs. Waffle slabs are preferred for spans greater than 40 feet (12 m), as they are much stronger than flat slabs, flat slabs with drop panels, two-way slabs, one-way slabs, and one-way joist slabs.
Description (Waffle Slab)
- Slabs required supports which is given in the form of columns so that the load coming on the slab can be transmitted through it at the foundation. But sometimes the columns act as an obstruction where longer space is required.
- In the Construction of auditorium, Large seminar halls and Airports required slabs with the longer spans. Conventional slabs cannot be constructed for the longer spans.
- Whenever longer area has to be covered without any hindrance, engineers recommend the Construction of this product.
- Waffle slabs are the best option which is used when the structures are required with the longer spans. Waffle slabis also known as the Ribbed slab.
- Nowadays many Builders and Engineers are also recommended to use the waffle slab in the projects rather than conventional slabs.
- The thickness of the this product is very less as compared to a conventional slab. The Beam which is used in the waffle slab has more depth.
- The upper portion of the waffle slab is very thin which rests on the grid lines and laid perpendicular to each other.
- this product is generally used in the Cinema Halls, Railway Station, Auditorium, Airports and in the structures where a large number of columns cannot be construed.
- this product is used where we have to design the structures for the longer spans. Waffle slabs are best suitable for slabs where high vibration Control is required.
