Ribbed Floor Slab

Ribbed waffle slab system.

Ribbed floor slab.

They are either one way spanning systems known as ribbed slab or a two way ribbed system known as a waffle slab. The extended part is known as ribs. They provide a very good form of construction where slab vibration is an issue such as laboratories and hospitals. Century the prevalent materials used for floor systems were timber masonry brick and tile.

Nervi ribbed slabs isostatics floor systems computational tool. A ribbed slab giving considerable extra strength on one direction. 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.

The slab is the flange of the beam and the extended part is the web. Ribbed floor slab one way joists. Ribbed slabs are made up of wide band beams running between columns with narrow. Ribbed floors consisting of equally spaced ribs are usually supported directly by columns.

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 or waffle slab is a slab system which consists of series of parallel reinforced concrete t beams framing into reinforced concrete girders. Sandwich slab reinforcement details in reality sandwich slabs are ribbed slabs with a slab placed both to their upper and lower surface. This form of construction is not very common because of the formwork costs and the low fire rating.

The spacing between the ribs should be in general 20 30 inch.
