What is a one way slab?
A one-way slab is supported on two opposite sides, so structural action is only ever in one direction. Total load is carried in the direction perpendicular to the supporting beam. Main reinforcement is provided in only one direction. Nominal distribution reinforcement is provided in cross direction.
What is one way or two way slab?
The basic difference between One Way and Two Way Slab is that the bending moment occurs only in one direction i.e. the shorter direction in One Way Slab while in Two Way Slab bending moment occurs in both directions i.e. shorter and longer.
What is one way slab formula?
One Way Slab Reinforcement Details: In the above slab, Larger span/Shorter span = Lx/Ly = 4500/2000 = 2.5 Which is > 2. So it is a one way slab. In this slab, the main reinforcement bars are provided on the shorter side and distribution bars are provided on the longer side.
Why one way slab is used?
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 design of one–way slab is simple and can be carried out easily. Slabs are used to provide flat, useful surfaces.
What is the minimum dia of bar?
As per IS 456:2000, in Circular/rectangular/square shaped RCC column, compressive member, vertical support, minimum diameter of reinforcement bar/ longitudinal bar used is 12mm. All structural engineer recommends of 12mm dia bar as minimum diameter of longitudinal bar for column.
What are the types of two way slab?
There are mainly three types of designs for two-way slab.
- Two-way solid slab (with beams) Two-way Solid Slabs on Beams.
- Two-way Waffle Slab (with Beams) Two-way Waffle Slab (with Beams)
- Two-way Waffle Slab (with Integral Beams) Cast in Situ Two-way Waffle Slab with Integral Beams.
What is LX and LY in slab?
Lx- Length of shorter side of slab( Shorter span) Ly- Length of longer side of slab( Longer span)
Where do we give one way slab?
Types of Designs for One-way Slab
- There are mainly three types of designs for one-way slab.
- In one-way solid slab (with beams) system, the slab is supported on beams.
- One-way Ribbed Slab (with beams)system is used for the office buildings (low rise), parking structures, and warehouses.
Where we can use two way slab?
The two-way slab is a slab which is generally supported on all sides of walls or beams, and whose length to breadth ratio is less than two and it twists or bends in both direction while transferring the loads to the walls or beams.
Is RCC a slab code?
IS456: 2000
Reinforced Concrete Slab Design and Detailing Guide IS456: 2000.
Which slab is better one way or two way?
Which slab is better one way or two way? If L/b the ratio is greater than or equal 2 or then it is considered a one-way slab. If L/b the ratio is less than 2 then it is considered a two-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.
What is meant by 1WAY slab and 2 way slab?
The two-way slab is supported by the beam on all four sides. In a one-way slab, the load is carried in one direction perpendicular to the supporting beam. In a 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.
What is definition of one way slab?
Sharing the details, sources said, ECC considered the principles and three phases of subsidy reforms on a summary submitted by the Ministry of Energy (Power Division) on April 30, 2021 and cleared mechanism for the first phase of the subsidy reform.
Where are one way and two way slabs used?
This type is commonly used in a multi-storeyed building, where floors need to support the weight of additional floors. The best way to determine which type you need is to review the breadth and width of a particular project. If one direction is longer than the other by a ratio of two to one, then you should consider a one-way slab. 3. Kitchen Slab
