Introduction

Stirrups are vital for reinforcing beams and columns. Accurate cutting length calculation ensures a perfect fit, enhancing structural integrity.

Required Data

1. Column Overall Breadth (mm)

2. Column Overall Depth (mm)

3. Stirrups Diameter (mm)

4. Clear Cover (mm)

Cutting Length Formula

Cutting Length = 2 × ( ( Breadth − 2 × ( Cover + Bar Diameter ) ) + ( Depth − 2 × ( Cover + Bar Diameter ) ) ) + (24 × Bar Diameter)

Example

Given:

• Breadth: 300 mm

• Depth: 500 mm

• Diameter: 8 mm

• Clear Cover: 25 mm

Calculation:

1. Adjust dimensions for cover and diameter:

a = 300 − 2 × (25 + 8) = 234mm 

b = 500 − 2 × (25 + 8) = 434mm

2. Calculate cutting length: 

Cutting Length = 2 × (234 + 434) + (24×8)

Cutting Length = 1336 + 192 = 1528 mm or 1.528 Meter
