Answer / dhiraj sengar
let 8mm dia is used
4x220+2(10x8)-5(2x8)= 960mm
where, 300-2x40= 220
2 times 10x dia for hook
5 times 2x dia for bends
hence cutting length of bar for ring is 960mm

Answer / lalit mohan upreti
Beam size 300 x 300,cover-40mm
less cover=300-40-40=220,
parameter of ring=2*(220+220)=880mm,
add for hock=10d=10*8=80mm,Where d=8mm
number of Hock=2
Total Hock length=2*10d=80*2=160mm,
Deduction for bend junction,for every junction less 2d,wherw d is the dia of Bar,
number of bend=5,
Total deduction =5*2d=5*2*8=80mm,
Total cutting cutting length of Ring=(Parameter of Ring)+ (Total hock length)-(Total bend deduction)
Total cutting length=880+160-80=960mm

Answer / 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

BBS MEANS BAR BENDING SCHEDULE.
SECOND OF QUESTION WRONG. THIS QUESTION ONLY MENTIONED ON
COLUMN SIZE AND COVER WIDTH.
NO MENTION ON COLUMN LENGTH.

[{2*(300+300)}-{2*(40+40)}]
[{1200}-{160}]
1040length
Lenth- bend of rings
1040-5*(1.5d)
1040-5*(1.5*8)
1040-5*(12)
1040-60
980mm length of 1 ring

Answer / devender singh
BBS is bar bending schedule.the ring size of 300*300 column
will be 300-2*40=220mm.for bending 75mm should be taken for
each of two ends.the total no of bends will be 5.if 8mm dia
bar is used then cutting length will be 4*220+2*75-
5*2*8=950mm

Answer / manjesh yadav
220*2 220*2 2*10*8-2*5*8= 960
MNS= (Anchoered Length) 2*10* Dia Of Bar - 2* No Of Bend(5)* Dia Of Bar
80
So Total Length =960mm

Answer / amit sharma
300*300 10dia
Cover deduction from sides 40*2=80
1. Ring size = 300-80 = 220
Sides 4*220=880
2.For hook take 10*d=10*10*2 = 200
Now deduction for bend. so below 16 dia its 1.5d or above 2d so
5*1.5*10 = 75
Now = 880+200+75 =1155
Now every one forget one thing when we bend the ring around the bar suppose that bar is 32 dia so dia/2 is also include at every bend of the ring.

Answer / er. amit sagar
Only for ring calculation-
Column size 300×300, 8mm dia of bar
Cover 40mm, 2×40 =80 mm
Total length= 4×(300-80)= 880 mm
2 nos. Hook= 2×(10d)=2×10×8=160mm
5 nos. Bend= 5×(2d) , for 90 degree
= 5×2×8
= 80 mm (deduction)
Total cutting length= total length+hook length-deduction
=880+160-80
=960 mm ( for 1 nos. ring length)
