minimum slab thickness, cantilever = L/10
thus; h = 1750/10 = 175mm (min.), but needs to check deflection
reference, table 5.1 minimum slab thickness "h" page 206,
design of concrete structures by, george winter, arthur nilson 9th ed 1980 "very old book"
sample loading from a 4 storey bldg i designed (uniformly distributed load only)
SECOND/FOURTH FLOOR SLAB:
DL: RC SLAB = 0.115m(24kN/m.m.m) = 2.76kN/m/m
FLR. FIN. = 0.05m(24kN/m.m.m) = 1.20 kN/m/m
MOVABLE PARTITION (LIGHT WALL) = 1.00 kN/m/m
ACOUSTIC BOARD = 0.12kN/m.m = 0.12 kN/m/m
