Get started with your design
The Timber Beam Design to AS 1720.1-2010 tool is built to assist engineers and designers in efficiently selecting and verifying timber members subjected to bending, such as rafters and joists. Using the Ultimate Limit State (ULS) methods, this tool ensures that your timber beams meet the necessary flexural and shear requirements, as specified in the AS 1720.1-2010 standard.
This tool is for:
- Structural engineers looking to streamline their timber design process and ensure compliance with Australian Standards.
- Architects who need to confirm the structural adequacy of timber beams in their designs.
- Construction professionals who require accurate and reliable timber beam designs for building projects.
With its parametric nature, this technical document offers flexibility in making adjustments to material properties, load conditions, and design constraints, leading to faster decision-making and the ability to quickly produce multiple design iterations. By automating complex calculations, this tool saves valuable time and ensures design accuracy, reducing the risk of errors in the design process.

FAQs
What are the main factors affecting timber beam design?
Timber beam design is influenced by the type of timber, the loading conditions, span length, and support conditions. It’s also critical to account for environmental factors, such as moisture, which can affect the beam’s strength.
How does AS 1720.1-2010 address safety factors in timber design?
AS 1720.1-2010 defines safety factors in terms of material properties, load duration, and environmental conditions, ensuring that timber designs meet both strength and serviceability requirements through ULS checks.
What are the common failure modes in timber beams?
Timber beams can fail due to flexural stresses exceeding the beam’s capacity, shear failure near the supports, or buckling under compressive forces. Each of these modes is addressed in timber design standards to ensure structural stability.

How to prepare an engineering report
Engineering reports require a balance of clarity, precision, and professionalism. Here are some best practices for preparing a report we use at CalcTree:
- Clear and visual: Use heading types to establish a logical structure, add diagrams for clarity.
- Integrate sources: Map data from your calculation tools such as spreadsheet or Python to your report.
- Units: Assign units to physical quantities.
- Compliance: State and hyperlink the relevant codes of practices.
- Peer review: Share a link to your page with team members for reviews and feedback.
