    4 Short Span Lx Lx = 4.00 M

    5 Long Span Ly Ly = 5.00 M

    6 Thickness of Slab T = 200 mm

    7 Cover to reinforcement Cc = 20 mm

    8 Live Load 3.00 kN/m2

    9 Finish Load 1.00 kN/m2

    10 Type of Slab Panel

    Load

    1 Self weight of slab Sw = 5.00 kN/m2

    2 Live Load LL = 3.00 kN/m2

    3 Finish Load FL = 1.00 kN/m2

    4 Misc Load ML = kN/m2

    1 Total Factored Load L = 22.09 kN/m2
