What is one way slab design?
What 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 oneway slab?
The one-way slab is a slab, which is supported by parallel walls or beams, and whose length to breadth ratio is equal to or greater than two and it bends in only one direction (spanning direction) while it is transferring the loads to the two supporting walls or beams, because of its geometry.
What is difference between one way and 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. 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.
How reinforcement is provided in one way slab?
One Way Slab Reinforcement Details: To provide adequate support on the larger side, the main reinforcement bar is provided perpendicular to that side or parallel to the shorter direction. Distribution bars are provided in the longer direction, which won’t help in carrying any load (refer to below image).
Which slab is best one way or two way?
Difference Between One Way Slab And Two Way Slab:
| One Way Slab | Two Way Slab |
|---|---|
| Main reinforcement is provided only in one direction (Shorter side). | Main reinforcement bars are provided in both directions. |
| The deflected shape is cylindrical. | The deflected shape is like a dish or saucer. |
Where is one way slab and two way slab used?
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. Chajja and Varandha are practical examples of one-way slab. Whereas two-way slabs are used in constructive floors of the Multistorey building.
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 slab and its types?
A reinforced concrete slab is a planar structural element and is used to provide a flat surface (floors/ceilings) in buildings. On the basis of reinforcement provided, beam support, and the ratio of the spans, slabs are generally classified into one-way slab and two-way slab.
What are the types of two-way slab?
How is slab calculated?
The current tax slab starts at 5% for income between ₹2.5 lakh and ₹5 lakh, 20% if your income is between ₹5 lakh and ₹10 lakh and 30% for income above ₹10 lakh, for individuals less than 60 years old.
What are the steps to design a slab?
Step 1: Preliminary Design. Find depth of slab using deflection control criteria. Take span/d = 28 for simply supported slab and 32 for continuous slab. D ≥ D min = 100mm for normal design and 125mm for earthquake resistant design. Step 2: Analysis of Slab. Slab is analyzed by IS code method.
Where are one way and two way slabs used?
The one way and two way slab systems are the most commonly used floor system in the reinforced concrete structure . These slabs are constructed to provide flat surfaces, usually horizontal, in building floors, roofs or other types of structures.
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 is one way slabs are used?
A one-way slab has moment-resisting reinforcement only in its short axis, and is used when the moment in the long axis is negligible . Such designs include corrugated slabs and ribbed slabs. Non-reinforced slabs may also be considered one-way if they are supported on only two opposite sides (i.e. they are supported in one axis).
