Ring no. 1
a= [ { 400 – ( 2 x cover ) – (
2 x stirrups dia. ) – ( 2 x half of bar ) / 3 }x2] + ( 2 x half of bar ) + ( 2
x half of stirrups of bar )
a= [ { 400 – ( 2 x 30 ) – ( 2 x
8 ) – ( 2 x 10 ) / 3 }x2] + ( 2 x 10 ) + ( 2 x 4 )
a= 230.7 mm
b= 500 – ( 2 x cover ) – ( 2 x
half of stirrups dia. )
b= 500 – ( 2 x 30 ) – ( 2 x 4 )
b= 432 mm
Cutting length = (2 x a) + (2 x
b) + (2 x 10d) – (3 x 2d) – (2 x 3d)
= (2 x 230.7) + (2 x 432) + (2
x 10 x 8) – (3 x 2 x 8) – (2 x 3 x 8)
= 1389.4 mm
= 1.3894 meter
Ring no. 2 same as Ring no.1
