What is a BBS?Find out the cutting length for a 300*300 column with 40 mm cover?

Answer Posted / surya kant upreti

given size of column 300X300 suppose ring bar is 10mm dia,
1st step
deduction for cover both side (40X2)=80mm
then ring size (300-80)=220mm
since column is square so its have 4 sides then
(220X4)=880mm
2nd step
for hook length take 10xdia of bar, then
(10dx2)=(10x10x2)=200
3rd step
deduction for bar devlopment in TMT at 90 degree bends:
5 bend, each bend devloped in lenght (2x dia of bar) then,
(5x2x10)=100mm

final calculation
step1+step2-step3=(880+200-100)=980mm

so length of bar for ring will 980 mm
