Detailing Requirements of Reinforced Concrete Slab as per IS456: 2000
a) Nominal Cover:
For Mild exposure - 20 mm
For Moderate exposure - 30 mm
However, if the diameter of bar do not exceed 12 mm, or cover may be reduced by 5 mm. Thus for main reinforcement up to 12 mm diameter bar and for mild exposure, the nominal cover is 15 mm.
b) Minimum reinforcement:
The reinforcement in either direction in slab shall not be less than
0.15% of the total cross sectional area for Fe-250 steel
0.12% of the total cross-sectional area for Fe-415 & Fe-500 steel.
c) Spacing of bars:
The maximum spacing of bars shall not exceed
Main Steel - 3d or 300 mm whichever is smaller
Distribution steel -5d or 450 mm whichever is smaller Where, ‘d’ is the effective depth of slab. Note: The minimum clear spacing of bars is not kept less than 75 mm (Preferably 100 mm) though code do not recommend any value.
d) Maximum diameter of bar:
The maximum diameter of bar in slab, shall not exceed D/8, where D is the total thickness of slab.
Procedure Steps for One Way Slab in the below section.
Design of One way slab
1.Based on the stiffness requirement assume suitable depth and calculate the effective span
2.Calculate the loads acting on the slab.
3.Calculate factored moment and shear force by considering the one-meter width of the slab
For simply supported slab
Factored moment =Mu= Wu× l²/ 8
Shear Force = Vu = Wu×l / 2
4.Determine the minimum depth required to resist bending moment by equating
Mu= Mulim = k×fck×bd²
b=1000mm
k=0.138 For Fe 415 steel and k=0.148 for mild steel
The depth provided should be more than this value
5.Determine the area of steel considering meter width of the slab.
6.Determine the spacing of bars by using
S= ast/Ast ×1000
ast - area of bar used
Ast- total area of steel required
Spacing should be more than 3d or 300mm whichever is less
7.Distribution steel provides minimum reinforcement as distribution steel at a spacing of 5d or 450mm whichever is less.
8.Slab is checked for deflection shear and development length.In case of slabs( thin members), no need of even minimum shear reinforcement.Shear due to loads always must be less than the shear strength of concrete.

Welcome.... Have a nice day.....

[@Scofield9975]

One thing i will say sir....YOU ARE THE ONLY ONE WHO HAS EXPLAINED THIS TOPIC PERFECTLY.....MY ALL DOUBTS ABOUT DETAILING ARE CLEARED..

[@civilpositive805]

Thanks... For support me...👍

The word" teacher" meaning define by ur teaching style and explanation
& thanks fram JADAVPUR UNIVERSITY.....😍

[@civilpositive805]

Thnks

[@hanamantraysk4927]

In Check for minimun reienforcement you should use 0.12%bD because you used hysd bars (Fe415).

[@abhinandankumar-mn3tf]

We cant always use fe415 bars so we may use 0.15 % as mild steel.

[@shortvdo69]

You are correct 💯

[@jatindadwal2492]

When ur teaching is passion and not a work ! Loved ur explanation ❤️

[@kshitijkumarkushwaha8903]

I recommend you not to watch this video if you are watching just before exam bcoz you will get confused instead watch engineer ki pathsala (it is lengthy ) but you will understand everything
But this lecture was also good.

A reinforced concrete floor system consists of
a 100 mm thick slab cast monolithically with
beams having an effective span of 6 m and
spaced 3 m centre to centre. The superimposed
load on floor is 6 kN/m2. Design the beam
using M 20 grade concrete and Fe 250 grade
of steel
