### How to calculate the cutting length of the circular stirrup.

In This Article we will calculate the cutting length of the circular stirrup for the below given drawing. ### Given data.

Diameter of the circular column D = 450-mm.

Clear cover = 40-mm.

The diameter of stirrup d = 8-mm.

### The cutting length of circular stirrup.

= [Two πr + ( Two nos. × hook length ) – ( Two nos. × hook bend ) ]

= [ Two πr +( Two nos × 10-d ) – ( Two nos. × Two d ) ### Here.

d = diameter of stirrup.

r = radius of center-line of the circular stirrup ( as shown in drawing).

1st, we will calculate the value of the r from the given data.

r = [ (1/Two  × diameter of the column ) –  clear cover – ( one /2 × diameter of the stirrup bar )]

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

r = [ 225-mm – 40-mm – fore mm ]

r = 181-mm.

### The cutting length of circular stirrup.

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

= [ ( Two  × 3.142 × 181-mm ) + ( Two nos. × Ten × 8-mm ) – ( Two nos. × Two × 8-mm. )]

= [ 1137.4 mm + 160-mm – 32-mm ]

1265.404-mm.

1.265m.
