### How to calculate the cutting length of a circular stirrup?/ Cutting length of the circular lateral ties.

For the calculation procedure, go through the following steps.👇

Now, let us calculate the cutting length of the circular stirrup for the below-given drawing.

Given data:

Diameter of circular column D = 450mm.

Clear cover = 40mm.

The diameter of stirrup d = 8mm.

The cutting length of the circular stirrup

= [2πr + ( 2nos. × hook length ) - ( 2nos. × hook bend. ) ]

= [ 2πr +( 2nos. × 10d ) - ( 2nos. × 2d )

Here,

d = diameter of the stirrup.

r = radius of the centerline of the circular stirrup ( as shown in the drawing).

First, we will calulate the value of r from the given data.

r = [ (1/2 × diameter of column ) -  clear cover - ( 1/2 × diameter of stirrup bar )]

r =  [ (1/2 × 450mm ) - 40mm - ( 1/2 × 8mm ) ]

r = [ 225mm - 40mm - 4mm ]

r = 181mm.

The cutting length of the circular stirrup

= [ ( 2 × π × 181mm ) + ( 2nos × 10d ) - ( 2nos. × 2d ) ]

= [ ( 2 × 3.142 × 181mm ) + ( 2nos. × 10 × 8mm ) - ( 2nos. × 2 × 8mm. )]

= [ 1137.4 mm + 160mm - 32mm ]

= 1265.404mm

= 1.265m.

Thank you for going through this calculation. Have a good day😄
