    Slab =S5 (One way is designed for maximum span)

    Fy = 500 N/mm²
    Fck = 25 N/mm²
    Clearcover 20 mm
    Th. Of the slab 125 mm HenceO.K
    Clear span 2.75 m
    Eff.span 2.75 + 0.101 = 2.851 m
    Taking the lesser value(as per code) lx = 2.851 m
    Slab thickness = 125 mm
    D.L.of slab = 3.13
    Celling plaster & brick coba 1.50
    Live load = 3.00 Eff.depth 101
    Total 7.63 kN/m²
    Ast Required Ast Provided
    M=1.5*(W*Lx²/10)= 11.62 kN-m Ast 8 mm Ast 8

    Distribution steel= 0.12*1000*d/100= 150 335 c/c 402 125
    Maximum spacing limits .
    For main bars 3*d (or) 300 mm 303 (or) 300 mm Whichever is less
    Provide 8 dia @ 125 mm c/c
    For dist. bars 5*d (or) 300 mm 505 (or) 300 mm Whichever is less
    Provide 8 dia @ 125 mm c/c
    Check for deflection as per IS:456-2000 (FIG.4)
    fs = 0.58*fy*Astreq/Ast prov. = 202
    Pt prov. = 100* Ast/b*d = 0.40 Modification factor = 1.60
    d required = lx/(k*20) = 68.6
    d provided = = 101.0 HenceO.K
