Spacing c/c = 150 mm
Bar used = 10 mm dia
Slab size = 12m× 6m
Number of main bar provided on the slab
= (12/0.15)+1
= 81 nos
Number of distribution bar provided on the slab
= (6/0.15)+1
= 41 nos
Total Length of
main bar = 81×6 m
= 486 m
Total length of
distribution bar = 41×12 m
= 492 m
Total steel bar
length on slab = 486m+492m
= 978 m
Total weight of steel bar required to the slab
= ((D×D)/162)×length
= ((10×10)/162)×978 m
= 603.7 kg
= 604 kg ans.
