Answer / sagar tiwari

For column cover is 40 mm both sides
here
300-40-40=220
600-40-40=520
For hook (10 times the dia meter of the bar)
so for 8mm = (80mm)
For bending (minus) 5X2d=5x2x8=80mm
Now the cutting length of the bar will be =
520+520+220+220+80+80-80
= 1560mm

ring size =220x520mm

Answer / ashfaque

BBS formula ..2(L+B)+2×10d-5×2d
Column size 600×300 Side cover 40
2×40-600 =520
2×40-300 =220
Total cutting of bar .
2(520+220)+2×80-80
2(740)+160-80
1480+160-80
1640-80=1560 mm

Answer / mukesh

column cover=40mm
L=600-40-40=520mm
B=300-40-40=220mm
length of master ring=520+520+220+220+2×10d-5×2d
(assume dia of ring =8mm)
1560 Ans

Answer / a.bidran

coln size 600x300 dia 8 mm
clear cover is 40 mm
hook is 10 d at 135 deg
=2(520+220) +2x10x8-(3x2d+2x3d)
=1480+160-(48+48)
1544

Answer / faiyaj ansari

600-80=520
300-80=220
520*2+220*2+2*10d-2*5d
=1560 mm

Answer / amit dutta

Column size 300 × 600 mm.
Column cover 40 mm.
Column hook 10d.
Column strip 8 mm.
2×(300-80+600-80)+10*8
1480+80 mm= 1560 mm.
Now deducted due to 90 degree bend 2d and 135 degree for 3d
So now total cutting length of strip is
1560 -72mm =1488 mm =1490 mm

Answer / mrutyunjaya sahani

L=600-80=520
B=300-80=220
Cutting lenth formula=2(l+b)+2*10d-5*2d
2(520+220)+10*8
2(740)+80
1480+80=1560mm
Ring size= (220*520)mm

Answer / ravindrarana8421

Cutting Length of a column Formula =

2(L+B)+20d-2x10d

So,
L=600-80=520mm
B=300-80=220mm

Cutting Length = 2 (520+220) + 10x8
= 2(740)+80
= 1480+80=1560 mm
if we Assume that the dia of ring is 8mm.
