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)
