Cutting Length Of Circular Stirrups

In this post I am going to explain you, How To Calculate the Cutting Length Of Circular Stirrups at site in very easy steps.

Here I have Considered a column whose Diameter is 900 mm.

This Column contains 8 Longitudinal Main Bars and a Stirrups of diameter 8 mm.

I have taken 40 mm Clear cover.

Let us first calculate the value of ‘r’ From the above figure,

The formula for calculating the value of ‘r’ is given below.

r = Radius of Circle – Clear cover – Half of Stirrups diameter

= 450 – 40 – 4

= 406 mm

Formula for Cutting Length of Circular Stirrups

= (2 x π x r) + Hook Length – Bend

= (2 x π x r) + (2 x 10 x d) – (2 x 2 x d)

= (2 x 3.14 x 406) + (2 x 10 x 8) – (2 x 2 x 8)

= 2677.68 mm or, 2.68 meter
