Find the total weight of stirrups (rings) needed for your structural member.

📐 Formula & Method

Cutting Length = 2 × ( (W-2c) + (H-2c) ) + 24d (for hooks) - 3×2d - 2×3d (bend deductions). Simplified: 2(a+b) + 24d.

Length = 2 × (a + b) + 24 × d

📋 Worked Example

230×450mm beam, 25mm cover, 8mm stirrup:
• a = 230-50 = 180, b = 450-50 = 400
• Length = 2(180+400) + 24(8) = 1160 + 192 = 1352 mm

❓ Frequently Asked Questions

What is a stirrup hook length?

Standard hook length for stirrups is 10d to 12d at each end (total 20-24d) to ensure the ring stays closed during earthquakes.
