What is 2 way reinforced concrete slab?
What is 2 way reinforced concrete slab?
What Is Two Way Slab? When a reinforced concrete slab is 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 slab, the ratio of longer span (l) to shorter span (b) is less than 2.
What is a two way slab design?
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. So, the main reinforcement is provided in both directions for two way slabs. …
What is the minimum slab thickness for a two way slab?
Moreover, the minimum thickness of any two way slab without interior beams should not be less than the following: For slabs without drop panel 125 mm. For slabs with drop panel 100 mm.
How many types of two way slab are there?
Types of Two Way Slab: Two Way Flat Plates Slab. Two Way Flat Slabs. Two Way Waffle Plate Slab.
What is the difference of one-way slab and two way slab?
The one-way slab is supported by a beam on two opposite sides only. 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.
How thick should reinforced concrete be?
In general, 6 inch (150mm) slab thickness is considered for residential and commercial buildings with reinforcement details as per design.
What is the standard concrete slab thickness?
4 inches
Standard concrete floor slab thickness in residential construction is 4 inches. Five to six inches is recommended if the concrete will receive occasional heavy loads, such as motor homes or garbage trucks.
What are the steps to design a slab?
Steps to design a two way slab Determine the effective span of the slab – dimension (l x X l y) Assume an effective depth (d) on the basis of span to effective depth Analysis – Calculate the moment Consider the various loads due to Self weight Dead Load Live load Calculate the total load and factored load (1.5 * Total Determine the area of reinforcement ( Ast )
How do you prepare for a concrete slab?
Concrete Floor Slab Preparation consists of: Remove any old concrete blocks or waste material. Backfill all the low points under the concrete floor slab with hardcore 804 backfilling. Compacting with a mechanical Whacker Plate. Installing services. Installing insulation. Cutting floor mesh. Installing heating pipes (Plumber).
How do design one way slab?
Compressive Strength. The compressive strength of concrete is specified based on the following criteria.
What is one way and two way slab?
Two Way Slab. Two way slabs are the slabs that are supported on four sides and the ratio of longer span (l) to shorter span (b) is less than 2. In two way slabs, load will be carried in both the directions. So, main reinforcement is provided in both direction for two way slabs.
