    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.

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

    • @abhinandankumar-mn3tf
      @abhinandankumar-mn3tf 2 роки тому +2

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