The loading table calculations with different factors is given below:
Moment of resistant of span = 1040 kg m
D.L. = Thickness of slab x density of concrete (2.50 t/m3)
L.L. = Live load
S.L. = Shuttering Load
| SLAB THICKNESS mm | LOAD = D. L. + L.L.= (0.4 t / m2) + S.L.=(0.1 t / m2) | PERMISIBLE SPANS (m) | |||
