Is flat slab more expensive?
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. Flat slab structures are the best solution for high rise structure as compared to conventional slab structure.
What are the failure of flat slab?
This type of failure is the Ultimate Limit State observed in the presence of concentrated forces, caused by shear [1], [2]. In flat slabs, the columns introduce the concentrated forces and the failure occurs in the slab-column connection.
What is minimum thickness of flat slab?
Civil Engineering (CE) Question The minimum slab thickness is 125 mm or L/36 for interior continuous panels without drops and end panels with drops or L/32 for end panels without drops or L/40 for interior continuous panels with drops. The length L is the average length of the panel.
What is difference between flat and slab?
The main difference between flat slab & conventional slab-beam system is that the one is directly supported on the column while another system has a beam for support. In conventional slab-beam system, the load is transferred from slab to beam and ultimately beam to the column.
What is the advantage of solid slab?
i) Formwork is simpler and less costly. ADVERTISEMENTS: ii) Smaller thickness of deck thereby reducing the height of fill and consequently the cost of the approaches. iii) Simpler arrangement of reinforcement.
Is slab beam necessary?
It is appropriate when the architectural aesthetic is essential for the interior of the building. It helps to break the extensive slab panel into considerable size. It helps to achieve the desired floor height. It allows brickwork over the slab.
How do you prevent a column from hitting a flat slab?
Furthermore, it has been discovered that punching shear can be prevented by increasing the depth of the concrete floor slabs, or by increasing the diameter of the columns supporting the floor.
Which is the most critical section for flat slab?
Detailed Solution 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.
What is the minimum thickness of flat slab as per IS 456 2000?
2) As per IS 456-2000 the minimum thickness of RCC slab is restricted to 4 times of nominal size of aggregate. minimum thickness should not be less than 4.75 inches not forgetting factor of safety.
How do you calculate the thickness of a flat slab?
1, then the ratio shall not exceed 0.9 times the value specified above i.e., = 40 ´ 0.9 = 36, if mild steel is used. = 32 ´ 0.9 = 28.8, if HYSD bars are used It is also specified that in no case, the thickness of flat slab shall be less than 125 mm.
Where flat slab is used?
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.
Why have a flat slab?
Flat slabs allows Architect to introduce partition walls anywhere required, this allows owner to change the size of room layout. Use of flat slab allows choice of omitting false ceiling and finish soffit of slab with skim coating.
