The main difference between the two types is “drop beam”. A solid slab has drop beams whereas a flat slab has no drop beams, as a result the main problem with flat slabs is the “punching Shear” from the columns.

What is the difference between flat slab and solid slab?

The main difference between the two types is “drop beam”. A solid slab has drop beams whereas a flat slab has no drop beams, as a result the main problem with flat slabs is the “punching Shear” from the columns.

What is flat slab and its types?

Flat slab is a reinforced concrete slab supported directly by concrete columns without the use of beams. Flat slab is defined as one sided or two-sided support system with sheer load of the slab being concentrated on the supporting columns and a square slab called ‘drop panels’.

What is flat slab and where it is provided?

Flat slabs are mostly used in large industrial structures, parking garages, ramps, warehouse, high rise buildings and hotels. 2. They are also used where uses of beams are not required.

Where do you use flat slab floor?

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.

Is flat slab economical?

Flat slab structure is more economical than that of conventional slab structure. The cost of flat slab structure is reduced by 15.8% compared to conventional slab structures.

What is the maximum span for flat slab?

Theoretically there is no limit on maximum length. But practically and economically they are restricted. A flat slab between span of 6.0 to 9.0m is economically feasible.

What is flat slab write its advantages?

Advantages of Flat Slab

1 Flexibility in room layout. Partition walls can be placed anywhere. Offers a variety of room layout to the owner. False ceilings can be omitted.
6 Prefabricated welded mesh. Standard sizes Less installation time Better quality control.
7 Auto sprinkler is easier.

What is the minimum thickness of flat slab?

The minimum thickness of Flat slab shall be 125 mm.

What is the advantage of flat slab?

Which of the following are the disadvantages of flat slab?

Disadvantages of Flat Slab It doesn’t offer a large span. They are not suitable for masonry partition of brittle nature. It uses drop panels that may interfere with oversized mechanical ducting. They have middle strip deflection, which may be critical.

What is flat slab give advantages and disadvantages?

What is flat slab?

Flat slab is a reinforced concrete slab supported directly by concrete columns without the use of beams. Flat slab is defined as one sided or two-sided support system with sheer load of the slab being concentrated on the supporting columns and a square slab called ‘drop panels’.

What are the different types of Flab Slab construction?

Following are the types of flab slab construction: 1 Simple flat slab. 2 Flat slab with drop panels. 3 Flat slab with column heads. 4 Flat slab with both drop panels and column heads.

What is the difference between a flat slab and a column?

The moments in the slab are higher near the column, so the slab is thickened near the column by providing drops. Sometimes the drops are called the capital of the pillar. A flat slab reduces the overall height of the structure. These slabs are capable of lifting concentrated loads. They require less formwork.

What is a flat slab with drop panel and column head?

INTRODUCTION Flat slab Flat slab with drop panels Flat slab with column head Flat slab with drop panel and column head INTRODUCTION Uses of column heads : • increase shear strength of slab • reduce the moment in the slab by reducing the clear or effective span Flat slab with column head
