Answer / santosh singh

1) let cover for column be 40mm (as u have not mentioned)
formula to determine cutting length of stirrup is given below
cutting length= (2A+2B)+(24D)
A=LONGER LENGTH OF COLUMN-2XCOVER=400-40X2=320MM
B=SHORTER LENGTH OF COLUMN-2XCOVER=250-40X2=170MM
D= DIAMETER OF STIRRUP BAR IN MM
therefore
cutting length=2X320+2X170 + 24X8 =1172MM=1.172 meter
2) given cover 25mm (as u have mentioned)
formula to determine cutting length of stirrup is given below
cutting length= (2A+2B)+(24D)
A=LONGER LENGTH OF BEAM-2XCOVER=400-25X2=350MM
B=SHORTER LENGTH OF BEAM-2XCOVER=200-25X2=150MM
D= DIAMETER OF STIRRUP BAR IN MM
therefore
cutting length=2X350+2X150 + 24X8 =1192MM=1.192 meter

NOTE SLAB COVER HAS NOTHING TO DO WITH CAL.OF STIRRUPS
3) ASSUME cover 30mm (as u have NOT mentioned)
formula to determine cutting length of stirrup is given below
cutting length= (2A+2B)+(24D)
A=LONGER LENGTH OF COLUMN/2 -COVER=400/2-30=170MM
B=SHORTER LENGTH OF COLUMN-2XCOVER=250-30X2=190MM
D= DIAMETER OF STIRRUP BAR IN MM
therefore
cutting length=2X170+2X190 + 24X8 =912MM=0.912 meter EACH

NOTE I HAVE CONSIDERED 8MM DIA STIRRUP BAR EVERY WHERE
UPTO 12MM DIA BARS CAN BE USED AS STIRRUPS GENERALLY

information through this book ....i think no one has been able
to explain the correct method ....good luck

Answer / md gyasuddin ahsan

a) let the cover 40 mm.in column,then
cutting length of ring is= 2*(170+320)+2*10*d-10*d
where hooks are= 10d+10d
deduction bend=2*5*d=10d
so length is =1060 mm

Answer / manish

a) Column size= 250*400,
so, L=250, B=400, cover = 40mm, bar dia 8mm
Cutting length of stirrups
= 2(L+B)-(8*cover)+(2*10d)-(1.5d*nos of bends)

(2*10d) is for 2hooks,
1.5d is deduction for elongation at each bend

Calculation =2*(250+400)-(8*40)+(2*10*8)-(1.5*8*5)
Cut length= 1080 mm.

Answer / jaikumar

If Cutting length of ring is 250-40*2=170
400-40*2=320
Total =170+320*2=980mm+hook calculate 10*8+80
We elongation on the 8mm rod
minus =980+96+96=1172-5*8
1172-40=1132 mm

Answer / shashank

IN CASE OF COLUMN-
DIM.-200X400mm
CONCRETE COVER-
FOR COLUMN THICKNESS <250mm=25mm
FOR COLUMN THICKNESS >250mm=40mm

LENGHT OF TIE- 2A+2B=2X200+2X400=1200mm

NOW DEDUCT CONCRETE COVER-LENGTH OF TIE-COCNRETE COVER=1200-
2X40=1120MM

ALSO, DEDCUT BENDS- 2D FOR 45degrees
D FOR 90degrees

THEREFORE- CUT LENGTH OF TIE-1120-DX5=1120-2X8=1104mm(NO.
OF BENDS -5 )
Length of Hooks=10d=10x8=80MM
NO. OF hooks=2
Therefore-Length of Hook=2x20=160MM

CUTTING LENGHT OF BAR=1104+160=1264MM=1.264m

Answer / ajit umakant

A)CUTTING LENGTH FOR 8mm Strips=2(250+400)-(4*40)+(2*10*8)-(2*5*8)
=1300-160+160-80
=1220 mm 

Answer / hi123

Given Data : Column size = 250x400 Clear Cover = 40 mm Dia of Stirrup = 8 mm
Ans: To calculate cutting length first we determine the lengths A and B
So A = 250-2x40+2x(half dia of stirrup) = 250-80+2x4 = 178
B = 400-2x40+2x(half dia of stirrup) = 400-80+2x4 = 328
Deductions : For bents up we must deduct the values that for
45 degree bent = 1d
90 degree bent = 2d
135 degree bent = 3d where d = dia of stirrup
here in our case for the hooks there are 2 bends of 135 degree each
for the stirrup there are 3 bends of each 90 degree
so deductions = 2x3xd + 3x2xd = 2x3x8 + 3x2x8
Addings up ---> we have to add up hook lengths here in our case each hook length = 12 d so for 2 hooks the hook length = 12d+12d = 24d
So now the actual cutting length = 2(A+B)-2x3x8-3x2x8+24x8
= 2(178+328)-2x3x8-3x2x8+24x8
= 1012-48-48+192 = 1108 = 1.108 m.

Note : It is only correct answer I assure to you all which will be the elsewhere worthwhile in whole india you can check up

Answer / santosh deora

as per IS 2502
cutting length for rectangular ties will be 2A+2B+24d
where A & B inside dimension of stirrup, d dia (8mm)of bar
for column size 250x400 , nominal cover 40mm,
A = 250-80-16 = 154
B = 400-80-16 = 304
cutting length = (2x154)+ (2x304)+ (24x8)
= 1108

Answer / pravin k

A)CUTTING LENGTH FOR 8mm Strips=2(250+400-2*80+2*10*8-2*5*8)
=1140+160-80
=1280 mm
