Ribbed floors consisting of equally spaced ribs are usually supported directly by columns they are either one way spanning systems known as ribbed slab or a two way ribbed system known as a waffle slab. Sandwich slabs may have the disadvantage of a larger weight compared to the ribbed ones but on the other hand they have the advantage that their spans and supports behave in the same proper way. Ribbed and waffle slabs. Ribbed and waffle slabs provide a lighter and stiffer slab than an equivalent flat slab reducing the extent of foundations.

They provide a very good form of construction where slab vibration is an issue such as laboratories and hospitals. The extended part is known as ribs. It consists of a floor slab usually 5 10cm thick supported by reinforced concrete ribs. They are either one way spanning systems known as ribbed slab or a two way ribbed system known as a waffle slab.

The slab is the flange of the beam and the extended part is the web. Nervi ribbed slabs isostatics floor systems computational tool. Ribbed waffle slab system. The construction site which retained the artisanal masonry methods of evolution of concrete floor systems prior to the 20.

This form of construction is not very common because of the formwork costs and the low fire rating. Ribbed floor slab one way joists. Sandwich slab reinforcement details in reality sandwich slabs are ribbed slabs with a slab placed both to their upper and lower surface.
