This tool analyzes and checks each fillet weld in a weld group for in-plane loading using the Instantaneous Center of Rotation (ICR) concept. Then, the shear force at each end of each weld line is checked to ensure that the critical design shear is considered. All calculations are performed in accordance with AS 4100:2020.

The Fillet Weld Group Analysis to AS 4100 tool is an online technical report creation tool designed to streamline the analysis of fillet welds in weld groups subjected to in-plane loading. It leverages the Instantaneous Center of Rotation (ICR) concept to accurately evaluate the forces within each fillet weld, ensuring the design shear at critical points is checked against AS 4100:2020 standards. The tool automates these calculations, offering precise and reliable results for structural designs.
This tool is for:
- Structural Engineers: Ensure compliance with AS 4100 standards, and automate the calculation of weld forces to focus more on design decisions.
- Construction Professionals: Expedite the verification of weld group strength, especially when considering shear forces in structural components.
- Civil Engineering Students: Gain practical insight into the design and analysis of weld groups through real-world applications based on Australian standards.
This parametric technical document helps by providing a clear, concise, and detailed breakdown of the critical forces in a weld group, reducing time spent on manual calculations and allowing users to focus on design optimization and compliance.

FAQs
What is the Instantaneous Center of Rotation (ICR) concept in weld group analysis?
The ICR concept is used to determine the distribution of forces in a weld group, helping to identify where the maximum forces act on each weld line. This ensures the analysis covers the most critical load points in the weld design.
How does the critical design shear impact the safety of fillet welds in structural connections?
The critical design shear directly influences the strength of the weld group. It is crucial to check shear forces at both ends of the weld lines to ensure the connection can withstand the applied loads, preventing potential failures.
How does AS 4100 define the critical design shear for fillet welds?
AS 4100 sets out specific criteria for calculating the maximum permissible shear force that fillet welds must resist, ensuring they are designed to withstand both static and dynamic loading conditions.
