How To Calculate The Cutting Length Of Circular Stirrup
Now, let us calculate the cutting length of the circular stirrup for the belowgiven drawing.
Given data
Diameter of circular column D = 450mm
Clear cover = 40mm.
The diameter of stirrup d = 8mm.

The cutting length of the circular stirrupĀ
= [2Ļr + ( 2nos.Ā Ć hook length ) – ( 2nos. Ć hook bend. ) ]
= [ 2Ļr +( 2nos. Ć 10d ) – ( 2nos. Ć 2d )
Here,
d = diameter of the stirrup.
r = radius of the centerline of the circular stirrup ( as shown in the drawing).
First, we will calculate the value of rĀ from the given data.
rĀ = [ (1/2 Ć diameter of column ) –Ā clear cover – ( 1/2 Ć diameter of stirrup bar )]
r =Ā [ (1/2 Ć 450mm ) – 40mm – ( 1/2 Ć 8mm ) ]
r = [ 225mm – 40mm – 4mm ]
Ā r = 181mm.

The cutting length of the circular stirrup
= [ ( 2 Ć Ļ Ć 181mm ) + ( 2nos Ć 10d ) – ( 2nos. Ć 2d ) ]
= [ ( 2 Ć 3.142 Ć 181mm ) + ( 2nos. Ć 10 Ć 8mm ) – ( 2nos. Ć 2 Ć 8mm. )]
= [ 1137.4 mm + 160mm – 32mm ]
=Ā 1265.404mm
=Ā 1.265m.
