What is flat slab and its advantages?
Flat slab is a reinforced concrete slab supported directly by concrete columns without the use of beams. The advantages of applying flat slabs are many like depth solution, flat soffit and flexibility in design layout.
What is the use of flat slab?
Uses Of Flat Slab: 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.
What are the conditions in which flat slab is preferred?
Flat slabs are mostly used in auditoriums, high rise buildings, parking garages, etc. for construction of asymmetrical column layouts like ramps, floors with curved shapes, etc, flat slabs are preferred.
Which is the most critical action for flat slab?
The spacing of bars in a flat slab shall not exceed 2 times the slab thickness. 2. Critical section for shear in case of flat slabs is at a distance of d/2 from the periphery of the column/the capital / the drop panel, where d is the effective depth.
Why drop is provided in flat slab?
Uses of drop panels : Drop panels increase the shear strength of the flat slab floor (i.e it resists shear). Drop panels increase the flat slab’s negative moment capacity. Drop panels reduce deflection by stiffening the flat slabs.
What are the advantages of flat slabs over beams?
1. It reduces the overall height of the structure. 2. Flat slabs are capable to carry concentrated loads. 3. Requires less formwork. 4. As reinforcement detailing of flat slabs is simple it is easy to place. 5. Better quality control. 6. Installation of sprinkler and other piping and utilities are easier due to absent of beams. 7.
What are the uses of flat slab?
1. 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. 3. Or where the structure requires less formwork.
Is it possible to have large span in a flat slab?
In flat plate system, it is not possible to have large span. In flat slabs, the middle strip deflection may be critical. Compared to typical reinforced concrete two way slab system, the thickness of flat plate slabs are higher. What is slab? What is flat slab?
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.
