# How to Calculate cutting length (BBS) of rectangular stirrups?

## How to calculate proper BBS of any size of stirrups.

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

### Cutting the length of the stirrup.

**Given Data From Drawing.**

**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

How to calculate stirrup weight 8 mm diameter

total cutting length X .39 kg/m

How to calculate in (Inches / Soot)?

Hook Length = 10d or not Less Than 75 mm. Please explain very clearly.

10 d is standard you can say, means if you are using 8 mm bar for stirrups for making ring than hook length is 80mm

Minimum length is 75mm
