What is simply supported two way slab?

Simply supported slabs are classified as One way slabs and Two way slabs. One way slabs bend in one direction only and transfer their loads to the two support beams in opposite directions. Two way slabs bend in both directions, and transfer their loads and stresses on all four sides.

How do you reinforce a two way concrete slab?

1. Step 1: Check the Type of Slab. Centre-to-centre distance of longer span, ly= 4850 mm.
2. Step 2: Preliminary dimensioning.
3. Step 3: Load calculation.
4. Step 4: Moment Calculation.
5. Step 5: Check for Depth.
6. Step 6: Reinforcement Calculation.
7. Step 7: Check for shear stress.
8. Step 8: Check for deflection.

What is 2way slab reinforcement?

Two way slab is a slab supported by beams on all the four sides and the loads are carried by the supports along with both directions, it is known as two way slab. 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.

Is 456 a two way slab design?

The depth of slab depends on bending moment and deflection criterion. The effective depth d of two way slabs can also be assumed using cl. 24.1,IS 456 provided short span is <3.5m and loading class is <3.5KN/m.

What do you use to support two way slabs?

For a simply supported two-way slab a mesh reinforcement is provided to resist bending in both directions. For continuous slabs, hogging reinforcements are provided at top over supports and bottom bars are curtailed.

How is reinforcement used in a concrete slab?

In one way slab main reinforcement is parallel to shorter direction and the reinforcement parallel to longer direction is called distribution steel. In two way slab main reinforcement is provided along both direction. Slabs could be simply supported, continuous or cantilever.

Which is true of a one way slab?

Spinning one way supported on two sides such impact on the way in which the slab will bend. ffB. Spanning two ways which are supported on all and two-way slabs. depending upon its length-to-breadth ratio. A one- way slab is designed for the spanning direction only. breadth ratios. The one-way slabs are identified as follows.

Why is torsional reinforcement provided at corner of two way slab?

Torsion reinforcement shall be provided at any corner where the slab is simply supported on both edges meeting at that corner and is prevented from lifting unless the consequences of cracking are negligible.
