Which is better one way or two way slab?

The one-way slab is economical up to a span of 3.6 meters. Whereas the two-way slab is economical for the panel sizes up to 6m × 6m. In one-way slab quantity of steel is less. In two-way slab quantity of steel is more as compared to the one-way slab.

What are the difference between one way slab 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.

What are the advantages of one way slab?

ONE WAY SLAB:

• Because due to the huge difference in lengths, load is not transferred to the shorter beams.
• Main reinforcement is provided in only one direction for one way slabs.
• They are designed to transfer their general loads to the opposite support walls.

When should we use 2 way slab?

In two way slab, the ratio of longer span (l) to shorter span (b) is less than 2. In two way slabs, the load will be carried in both the directions. So, the main reinforcement is provided in both directions for two way slabs. Example: These types of slabs are used in constructing floors of a multi-storeyed building.

Where do we use 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 is one way slab and two way slab used?

Difference Between One Way Slab And Two Way Slab:

Why alternate bars are bent up in slab?

The crank bars or bent-up bars are essential in R.C.C beam or slab construction because without countering the Hogging (Negative moment), the structure will fail, or the strength of the structure will reduce. The hogging bending moment will develop at the supports of the slabs and beams.

What is a two way concrete slab?

Two-way slabs are slabs that are supported on four sides. In two-way slabs, the load will be carried in both directions, thus main reinforcement is provided in both directions for two-way slabs. The slabs are considered as spanning two-way when the longer to shorter span length is less than a ratio of two.

Which is better OPC and PPC cement?

PPC has an edge on OPC as PPC has slower rate of heat of hydration. Thereby PPC is prone to less cracks & reduced shrinkage), better workability and finishing (as fly ash based cement are spherical in shape and finer in size).

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 do design one way slab?

Compressive Strength. The compressive strength of concrete is specified based on the following criteria.

What is definition of one way slab?

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.
