Design procedure of one way slab.
Roof slab reinforcement design.
Rcc roof slab reinforcement details if you follow the minimum standards for structural design for modern day buildings you can opt for creating the rcc without a beam it is called a flat slab.
The slab has to carry a distributed permanent action of 1 0 kn m2 excluding slab self weight and a variable action of 3.
This is the design of roof how the reinforcement has been lated over here and how to be the covering lated over is 6 x6 inch and used 10 and 12 mm diameter bars.
Identify the type of slab.
Flexural reinforcement must be greater than 0 0018 psi or the shrinkage reinforcement.
Simply supported one way slab a rectangular reinforced concrete slab is simply supported on two masonry walls 250 mm thick and 3 75 m apart.
However the complexity of the generalized approach.
A stiff concrete mix specified at 3000 psi is pumped into place as workers advance up the slope to vi brate and finish the concrete to the desired thickness.
Design of slab examples and tutorials by sharifah maszura syed mohsin example 1.
In this video we learn how to reinforcement design in slab in autocad in hindi dear all slab two type ke hote hain one way slab two way slab slab me reinforc.
Determine h min and round it to higher 10mm multiple.
If reinforced concrete were to be reused strong connections would have to be made between roof and walls.
According to the 1995 aci code all two way reinforced concrete slab systems including edge supported slabs flat slabs and flat plates are to be analyzed and designed according to one unified method such as direct design method and equivalent frame method.
Maximum spacing of main bar is restricted to 3 times effective depth or 300 mm whichever is less.
Assume the thickness of slab take 4 cm per metre run of the span.
Minimum reinforcement is 0 12 for hysd bars and 0 15 for mild steel bars.
Steps to be followed in the design of slab assuming suitable bearings not less than 10cm find the span of the slab between the centers of bearings.
Reinforced concrete slabs are heavier and generate higher seismic forces in an event.
6 mm 8 mm 10 mm 12mm and 16mm.
However including the beams would effectively transfer a load of slabs to the columns which is good for durability of the structure.
The diameter of bar generally used in slabs are.
Thickness of the slab is decided based on span to depth ratio specified in is456 2000.
The maximum diameter of bar used in slab should not exceed 1 8 of the total thickness of slab.
Such slabs left unconnected to walls caused many deaths in the 2005 quake from school roof collapses.
Determine the dead load that is acting on the slab.
