so on iron bars for 45 digree and 90 digree bents plz tell
me if there is any formula or tabel to find it

Answer / 03265523
for example if any steel take 1.0 meter cutting length
density= weight / volume
density of steel is 7850kg/m3
volume of steel = areaX length=3.14xD2/4*1.0
weight of steel for 1m is= density X volume
=D2/162 (square of D/162)
where D is the dia of bar in mm
for 45degrres =cutting length-1 * dia of bar* no of bends
for 90 degrees= cutting length-2 * dia of bar*no of bends

Answer / bikash bhowmick
for calculation of cutting length deductions for 90 degree bend is......cutting length= total length- 2* dia of bar(upto 20) and 3*dia of bar when bar dia 25 and above......

Answer / dharvinder singh
it is not understanding that we have to deduct one dia for
both 45 degree & 90 degeree . their should be an other

Answer / prabhu
The answer posted should some reference from any of IS code.
It has to be justified.
As i refered code IS 2502 BS 4466 the deductions followed are
0 for 45 bends
d<= 16 dia for 90 bends
2d>=20 dia for 90 bends

Answer / pranjal bokare
there is a formula for finding out the extra length
required for one bent. i.e. 0.42d where d is the effective
depth of the member.

Answer / abhay
The best way to find out the cutting length of bar:
1 Check dia of bend of bar given in specification.
2.follow the formula given in BS 8666:2005 ir IS 2502-1963
this is best

Answer / arun
Total Length-2(Elongation)*Dia of Bar*No of Bend

Answer / muhammad abdullah
To calculate the bending Deduction formula given Below.
Bend Deduction = 1.25*Dia of Steel*No of Bend

Answer / deepak
1)for 90 degree bend 3/4of D
D=depth of the structure
2) for 45 degree use pythagars theorm
