# Cutting Length of Circular Stirrups

Calculation of Cutting Length of Circular Stirrups

———————————————————————————————-

#### Given value in drawing.

Diameter        = 500mm

Clear Cover    = 40mm (Add half of ring dia  in clear cover for effecting clear                                    cover)

Effecting clear cover = 44mm

Ring Dia  =  8mm

For Hooks  = 10d or 75mm

Band  = 3d for 135°

For Hooks  = 10d or 75mm

Band  = 3d for 135° (In circular stirrups band of hooks is 135° )

#### The formula for calculating cutting length of  circular stirrups

Length of Circular ring  = Circumference of Ring + 2 numbers of hooks – 2 numbers of 135° bends

Circumference of ring         = 2丌r

Diameter of ring             d    =500

Radius or column             r  =d/2 =500/2

Radius of ring                         = 250-44 =206

Length of Circular ring     = Circumference of ring + 2 no. of hooks – Bend Deduction

Length of Circular ring      =(2𝑥3.14𝑥206)+(2𝑥10𝑥8)-(2𝑥3𝑥8)

Sir ek aur request ki bbs of one way slab Or two way slab bhi bana do

4. Om says:

Sir bend deduction aapne minus kiya hai….
Bend deduction plus ho jayega
