Calculation: Cutting Length of Circular Stirrups
Calculation of Cutting Length of Circular Stirrups
Before calculate any BBS please read Civil Structure drawing care fully.
———————————————————————————————-
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° )
Formula for calculate 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)
= 1405.6 mm
= 1.40m

Sir bbs of stair case ka excel sheet bhi bana do plz it is humble request aapka sheet bht acha thank u bry mch…
Sir ek aur request ki bbs of one way slab Or two way slab bhi bana do
Sir bend deduction aapne minus kiya hai….
Bend deduction plus ho jayega
