🔗 Stirrup Calculator UAE — Free Online Tool
Stirrups (shear links) are essential for every reinforced concrete beam and column in UAE construction. They resist shear forces, prevent buckling of main bars, and confine the concrete core. Accurate calculation of cutting length before bending saves significant steel wastage on UAE construction sites.
How to Use This Calculator
- Enter beam or column width and depth in millimetres
- Enter concrete cover to main bars in millimetres
- Select stirrup bar diameter — T8 is most common for beams
- Enter total number of stirrups required
- Click Calculate for cutting length and total weight
🇦🇪 UAE Tip: Standard hook length for UAE stirrups is 10 × bar diameter (10d). For earthquake zones or special structures, 135-degree hooks with 10d extension are required by UAE Civil Defence. Always follow the structural engineer’s bending schedule. Add 5% to cutting length for bending losses.
Stirrup Cutting Length Formula
Cutting Length = 2(B – 2c) + 2(D – 2c) + 2(10d)
Where: B = Beam Width, D = Beam Depth, c = Cover, d = Stirrup Diameter
Standard Stirrup Sizes — UAE Reference
| Element | Stirrup Size | Spacing Standard Zone | Spacing High Shear |
|---|---|---|---|
| Residential Beam | T8 | 150mm | 75mm |
| Commercial Beam | T10 | 150mm | 75mm |
| Column Ties | T8 / T10 | 200mm | 100mm |
Frequently Asked Questions
What diameter stirrups for UAE beams?
T8 stirrups at 150mm centres for most residential beams. T10 stirrups for larger commercial beams. High shear zones near supports typically require closer spacing at 75-100mm centres per BS 8110.
How to calculate stirrup cutting length?
Cutting Length = 2(B-2c) + 2(D-2c) + 2(10d) where B=width, D=depth, c=cover, d=stirrup diameter. Our calculator does this automatically including hook allowances.
Can I use T6 stirrups in UAE?
T6 stirrups are occasionally used for small columns but are generally not recommended. Minimum T8 for most UAE structural applications per BS 4449 and UAE engineering practice.
