Ribbed floor slab.

It consists of a floor slab usually 5 10cm thick supported by reinforced concrete ribs. Ribbed and waffle slabs provide a lighter and stiffer slab than an equivalent flat slab reducing the extent of foundations. 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. The spacing between the ribs should be in general 20 30 inch.

The construction site which retained the artisanal masonry methods of evolution of concrete floor systems prior to the 20. Ribbed floor slab one way joists. 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.

Ribbed floors consisting of equally spaced ribs are usually supported directly by columns. A ribbed slab giving considerable extra strength on one direction. They provide a very good form of construction where slab vibration is an issue such as laboratories and hospitals. Sandwich slab reinforcement details in reality sandwich slabs are ribbed slabs with a slab placed both to their upper and lower surface.

Century the prevalent materials used for floor systems were timber masonry brick and tile.
