Answer / venkat

column size = 300x300
after removal of cover 40mm two sides=220mm
then, the ring will=((220x4)-(4x2x8)+75)=891mm
4=four corners of ring
for every 90degrees add 2d=2*8
add 75 mm for inner hooks

Answer / anilkumar prasad

Answer No 10 is correct

Answer / nitin baghel

LET DIA IS 8MM.
SIZE OF RING -
=4(220)+2(10d)-5(2d) means
=2(220)+2(10*8)-5(2*8)
=880+160-80=960mm.

Answer / eldridge

960 from my calculations

Answer / muzeem khan

given- column size 300x300mm


cutting length of column with cover = 2x300 2x300-4x40
=600 600-160
=1200-160
=1040mm
bending merging of column=
1040-4x8
=1040-32
=1008
size of ring = 1008 2x8x10
=1008 160
=1168mm

Answer / muthu selvam

BBS= BAR BENDING SCHEDULE. it use to calculate how much kgs
steel want to building. cutting length of column=880+140=1020mm

Answer / santosh deora

cutting length = 2A+2B+24d
A & B inner dimension of stirrup, d dia of bar
for 300x300 column cover 40mm A=B=300-80-16 = 204
d= 8mm
cutting length = 1008

Answer / raju rathod

I think Sumit Is Right
Column Cover Is 40mm
One Side Lenght Will be= 300-40=260 not 220 Is wrong

Answer / vishal s rao

BBS is Bar Bending schedule
For 300*300 size column
rings will be 300-(40*2)=220mm
220mm on 4sides i.e =880mm
for bending purpose on two end 75mm to be kept.
i.e 880+75+75=1030mm
For right angle 2*d to be added.
i.e 2*8*4=64mm
So totally = 1030+64=1094mm.

Answer / n.selvan

let 8mm or 10mm.
col size:300x300 and cover 40mm.
per side 300-(40*2)= 220mm
So 4 side 4*220= 880mm
Add for hook per ring = 50mm
Total length is 880+50= 930mm is sufficient.
This is practical.
