The Bolt Group Analysis to AS 4100 tool analyzes the performance of each bolt in a bolt group subjected to in-plane and out-of-plane loads, using the Instantaneous Centre of Rotation (ICR) concept. The tool checks the shear force, pull-out force, and combined action for each bolt, ensuring that all calculations adhere to the Australian Standard AS4100-2020.
This tool is for:
- Structural engineers designing and checking bolt group connections in steel structures, ensuring compliance with AS 4100.
- Steel fabricators who need to verify bolt groups for safety and load capacity before fabrication and installation.
- Engineering students and researchers studying bolt group behavior under combined loading conditions, utilizing industry-standard calculations.
This parametric technical document simplifies complex bolt group analysis, ensuring consistent and accurate results that comply with structural standards, ultimately improving design efficiency and reducing the risk of errors.

FAQs
What is the Instantaneous Centre of Rotation (ICR) concept in bolt analysis?
The ICR concept is used to determine how bolts within a group respond to forces applied at various angles. It helps in assessing the rotational and translational forces acting on each bolt, offering a more accurate representation of the bolt group's behavior under load.
How are combined actions on bolts calculated?
Combined actions refer to the simultaneous effects of shear and tension forces on bolts. The analysis ensures that the combined forces do not exceed the permissible limits outlined in the AS4100 standard, helping engineers verify the overall safety and performance of the bolt group.
What role does pull-out force play in bolt group design?
Pull-out force is the axial force that could potentially pull a bolt out of the connected materials. It is crucial in designing connections, particularly for bolts that experience significant tension. The tool calculates this force to ensure that bolts remain secure under load.
