ALL YOU WANT TO KNOW ABOUT STIRRUPS IN BEAM AND COLUMN

 A stirrup is a closed rebar loop that is used to hold the main rebar together in an RCC structure. In one column, the stirrups provide lateral support to the main bars against buckling.

Different Shapes of Stirrups

1)     Rectangular Stirrups

2)     Square Stirrups

3)     Circular Stirrups - Also use: Calculator for circular stirrups 

4)     Triangular Stirrups

5)     Spiral Stirrups

6)     Diamond Stirrups

Types Of Stirrups Used In Beam And Columns

1)     Single Legged Stirrups (Open stirrup)

2)     Two-legged or Double Legged Stirrups (Closed Stirrup)

3)     Four-legged Stirrups (Closed Stirrup)

4)     6-legged Stirrups (Closed Stirrup)

Steps involved in finding the cutting length of stirrups

1)     Look at the size of column or beam from drawings

2)     Adopt Dia of the bar (generally 8mm Dia is used for stirrups)

3)     Deduct the concrete cover or clear cover

4)     Find the total outer length of stirrup after deducting clear cover.

5)     Add the length of the hook to the length of the stirrup

6)     Deduct the length of bends

7)     Use below formula to find the total cutting length of stirrups

   

Formula To Find The Total Cutting Length Of Stirrups

Cutting Length of Stirrups = Perimeter of Shape + Total hook length – Total Bend Length

Perimeter Of Shape

Perimeter of Rectangle = 2 ( length + breadth)

Perimeter of Square = 4 x side length

Perimeter of circle or Circumference of Circle = 2πr = πd

(r= radius, d= Diameter of Circle)

Total hook Length

1 Hook length = 9d or 75mm

Total Bend Length

45° Bend length = 1d

90° Bend length = 2d

135° Bend length = 3d (Remember, d = Diameter of Bar)
