How to Calculate cutting length of rectangular stirrups?

Cutting length of rectangular stirrup is very important because in every Beam and Column,  we use stirrups and the mean is the most important part in the construction work. Its length and weight calculation is very easy and simple. Without known the proper length and proper quantity of the stirrups, it is very difficult to do the construction work properly.

Cutting length of the stirrup .

Given Data From Drawing.

tutorials tips

        a= 200 mm,      b= 600 mm

Column Size = 200 x 600

Stirrups bar size = 8mm

Cover = 25mm

——————————-

Hook Length = 10d or not Less Than 75 mm

Band Deduction

45° Bend  = 1d

90° Bend  = 2d

135° Bend  = 3d

——————————–

a= 200 mm and b= 600 mm ( Refer to Above Image for A and B Value ) 

Minus Both Side Cover from a and b

a= 200-(2𝑥25) = 150 

b= 600-(2𝑥25) = 550

 Cutting length of rectangular stirrups

Add a and b from both side than plus look length and than minus all type band.

Cutting Length = (2 𝑥 a) +(2 𝑥 b) +No. of hook – (No. of  90 degree bend)  -(No. of 135 degree  bend )

Cutting Length = (2𝑥a) +(2𝑥b) +(2𝑥10𝑥d) -(3𝑥2𝑥d) -(2𝑥3𝑥d)

 length = (2𝑥150) +(2𝑥550) +(2𝑥10𝑥8) -(3𝑥2𝑥8) -(2𝑥3𝑥8)

= 1464 mm

= 1.464 m

Weight of stirrups

= d2/162 x(Cutting Length) d= 8 MM

= 64/162 x 1.464 = 0.578 kg
