The Timber Nailed Joint Design to AS 1720.1-2010 tool enables users to design timber nail joint connections with precision by considering timber species and the geometry of nail groups. This tool assesses the capacity of nail joints connecting two or three timber members, accounting for applied axial or shear forces and moments. All calculations are compliant with AS 1720.1-2010, ensuring standards-based design for reliable, safe timber connections.
This tool is for:
- Structural Engineers: Assess nail joint capacities in timber structures, optimizing connections for load resistance and stability.
- Timber Framers: Validate that nail joints meet safety and structural standards, supporting efficient and compliant construction processes.
- Architects: Integrate well-designed, standards-compliant nail joints into timber projects to meet both aesthetic and structural needs.
This parametric technical document simplifies complex calculations, allowing users to adjust key variables such as timber species and nail configuration for precise joint design. By delivering clear, AS 1720.1-2010-compliant results, this tool supports safer, more reliable timber construction, saving time and ensuring design accuracy.

FAQs
What factors affect the load-bearing capacity of a nailed joint?
The capacity of a nailed joint is influenced by nail size and arrangement, timber species, joint geometry, and the direction of the applied forces, whether axial, shear, or moment-based.
How does timber species impact the performance of a nailed joint?
Different timber species have varying densities and strengths, which directly affect the grip and holding capacity of the nails. Higher-density timber can provide a stronger connection than lower-density timber.
How do axial forces and moments influence nailed joint design?
Axial forces and moments create different stresses within a joint. Axial forces act along the length of the timber members, while moments introduce rotational forces, both requiring careful design considerations to prevent joint failure.
