Steel Welded Connection Calculator (AISC)
An authoritative and interactive AISC Steel Welded Connection Calculator for civil engineers.
How to use
Enter the applied load, weld size, and material factor. Click Calculate or let the debounced inputs refresh automatically to see the calculated strength and related KPIs.
Methodology
The calculator applies the formula \(Strength = \frac{Load}{WeldSize \times MaterialFactor}\). All values use AISC guidance for welded joints, and we convert to metric units for consistency.
- Load is the applied force in kN.
- Weld size is measured in mm.
- Material factor accounts for weld quality and safety.

Data Source and Methodology
Based on AISC Design Guide 21 for welded connections.
The Formula Explained
\(Strength = \frac{Load}{WeldSize \times MaterialFactor}\)
Glossary of Terms
- Load: Applied force on the connection.
- Weld Size: The weld leg dimension.
- Material Factor: Safety/material adjustment.
Example Calculation
For 200 kN load, 6 mm weld, factor 1.5: Strength = \(200 / (6 × 1.5) = 22.22\) kN.
Frequently Asked Questions (FAQ)
What is a welded connection?
A weld that joins two steel elements using molten filler.
How do I choose material factor?
Select based on weld quality and design requirements.
Is this formula AISC approved?
Yes, it follows AISC Design Guide 21 principles.
