WHAT IS FLAT SLAB?

Flat slab is also known as beam-less slab because it is supported directly by columns or caps. Here, the loads are transferred directly to the columns.

The function of this type of slab is to provide a plain ceiling surface, which will give the best diffusion of light. They are commonly used in hotels, parking lots, commercial buildings or places where beam projections are not suitable for height controls or even aesthetics view.

Minimum thickness of the flat slab is 8” or 0.2m

 

APPLICATION OF FLAT SLABS

1.   Flat slabs or plain ceiling surface provide better diffusion of light

2.   It's economic friendly because it reduces formwork

3.   It can use where headroom Larger or storey height shorter & pleasing appearance.

4.   flat slabs are generally used in

a)   Parking slot

b)  Hotels

c)   Commercial buildings

d)  Places where beam projections are not desired and where the need of aesthetics view.

 

ADVANTAGES OF FLAT SLABS

1.  The height of the building can be reduced by minimizing floor to floor height where there in no need of false ceiling

2.   It develops good Auto Sprinkler system.

3.   Reduce construction time.

4.   Economical

5.   The shear strength of the slab increased

6.   Minimize the moment on the slab by minimizing clear or effective spacing.

 

DISADVANTAGES OF FLAT SLAB

1.   It's not used for large span design

2.   Not suitable for supporting fragile (masonry) partitions.

3.   slab thickness higher
