Introduction
This calculator allows the user to analyse and check each fillet weld within a weld group to ensure compliance with the Australian Standard AS 4100:2020. The user defines the weld group geometry by inputting the start and end coordinates of each weld line. Using user input forces, the calculator then checks the shear force at each end of each weld line to to ensure the critical design shear is considered.
A typical connection with a weld group is a beam to column welded connection.
❗This calculation has been written in accordance with Australian Standard AS 4100.
Calculation
Technical notes
- This calculator does not consider out-of-plane forces.
- This calculator checks for four weld lines only. For other amounts of weld lines, use the spreadsheet directly.

💡Explanation
Welding is used in the fabrication of steelwork and is particularly useful in connections and for combining several plates or sections into built-up sections with greater capacity then available rolled sections. More then one weld line forms a weld group. A weld group is subject to in-plane eccentric forces and moments.
