How is one way slab design?
One-way slab is a type of concrete slab in which loads are transferred in one direction to the supporting beams and columns. Therefore, the bending occurs in only one direction. The procedure of designing a one-way slab is similar to that of a rectangular beam. Slabs are used to provide flat, useful surfaces.
What is the formula of one way slab?
What is one way slab? According to IS 456:2000, The ratio of longer span(l) to shorter span(b) which is (L/B) greater than 2 is known as One way slab.
Under what circumstances you go for a one way slab?
If the L/b ratio is greater than or equal to 2 or then it is considered a one-way slab. If the L/b ratio is less than 2 then it is considered a two-way slab.
Where is one way slab used?
Due to the huge difference in lengths, the load is not transferred to the shorter beams. Main reinforcement is provided in shorter span and distribution reinforcement in a longer span. Example: Generally all the Cantilever slabs are one Way slab. Chajjas and verandahs are a practical example of one way slab.
What is the maximum span for one way slab?
A reinforced concrete slab is built integrally with its supports and consists of equal span of 15 ft. The service live load is 100 psf and 4000 psi concrete is specified for use with steel with a yield stress equal to 60000 psi.
What is meant by 1WAY slab and 2 way slab?
The one way slab is supported by a beam on two opposite side only. The two way slab is supported by the beam on all four sides. In one way slab, the load is carried in one direction perpendicular to the supporting beam. In two way slab, the load is carried in both directions.
Where are one way and two way slabs used?
In two-way slab, the load is carried in both directions. The deflected shape of the one-way slab is cylindrical. Whereas the deflected shape of the two-way slab is a dish or saucer-like shape. Whereas two-way slabs are used in constructive floors of the Multistorey building .
How reinforcement is provided in one way slab?
In one way slab, as one side is greater than the other side, the maximum load is carried by the larger side just so giving main reinforcement comparing to that load carrying side will be adequate. To provide adequate support on the larger side, the main reinforcement bar is provided perpendicular to that side or parallel to the shorter direction.
What are the types of slab?
Types of Concrete Slab Designs. Concrete slabs are common in building construction. Used for foundations, porches, decks, patios, and driveways, concrete slabs comprise several variations with four main designs: flatwork, the T-shaped foundation, slab-on-ground, and frost protected.
