Advantages and Disadvantages of Flat Slabs


A flat slab is a reinforced two-way concrete slab that usually has no beams and beams, and the loads are transferred directly to the supporting concrete columns.

Advantages of the flat slab

The panels use flat slabs in many buildings due to their advantages over other reinforced concrete floor systems in different cases. The most important advantages of flat slabs are given below:


1.Flexibility in the design of the room.
   
The dividing walls can be placed anywhere.
It offers a variety of room layout for the owner.
False ceilings can be omitted.

2.The placement of the reinforcement is easier.

As the reinforcement details of the flat slab are simple, it is easier to place

3.Ease of installation of the frame.

The large table frame can be used in flat slab.

4.The height of the building can be reduced.

As no joists are used, the height of the floor can be reduced and, consequently, the height of the building will be reduced.
Approximately 10% of the vertical member could be saved
The burden of the foundation will also be reduced.

5.Less construction time

The use of the large table frame helps reduce construction time

6.Prefabricated electro welded mesh.

Standard sizes
Less installation time
Better quality control

7.The automatic sprinkler is easier.

Disadvantages of flat slab

Flat slabs also have some disadvantages. The main disadvantages are given below.

1.The length of the section is medium.
In the flat plate system, it is not possible to have a large span.

2.It is not suitable for supporting fragile partitions (masonry)

3.The use of drop panels can interfere with larger mechanical ducts

4.Critical deviation of the middle band

In flat slabs, the deviation of the central strip can be critical.

5.Greater thickness of slab.

Compared with the typical two-way reinforced concrete slab system, the thickness of the flat plate slabs is greater.
