Span to effective depth ratio l/d = 32

Minimum effective depth d = 97.66 mm

Overall depth D = 127.66 mm

Provide Overall depth D = 150.00 mm

Dia of bars for short direction Φ=10mm

Dia of bars for long direction Φ = 10 mm

Effective Depth d=120.00mm

Loading on the slab

Dead Load of the slab (DL) 3.75.00kN / m2

Super Dead Load = 5.00 kN / m2

Live Load on the slab=3.00 kN / m2

Total Load on the slab (TL) =12.00kN / m2

Design Load = (Total Load x Load Factor i.e. 1.5) ie 18.00 kN / m2

Effective Span lx = 5.17 m

ly=5.17 m

Ratio ly/lx= 1.000 Two Way
