The Timber Beam Design to Eurocode 5 tool assists in designing timber bending members, such as rafters and joists, ensuring they meet the flexural, shear, bearing, deflection, and vibration requirements specified in Eurocode 5. The analysis also accounts for notches at the supports, which can impact the structural integrity of the beam. This tool ensures that all calculations are compliant with Eurocode 5, providing safe and reliable designs for timber structures.
This tool is for:
- Structural engineers designing timber beams and joists for residential, commercial, or industrial projects, ensuring compliance with Eurocode 5.
- Carpenters and timber construction professionals who need to verify that timber beams meet safety requirements for bending, shear, and deflection.
- Civil engineering students and educators studying timber design principles and looking for accurate, code-compliant examples to deepen their understanding of structural timber behavior.
This parametric technical document simplifies timber beam design by providing clear, code-based analyses that save time and reduce the chance of errors, helping to ensure structural safety and performance.

FAQs
What factors must be considered in the design of timber beams for flexural strength?
Timber beams must be designed to resist bending moments without exceeding their flexural strength, accounting for factors such as load distribution, beam span, and material properties.
Why is vibration performance important in the design of timber beams?
Vibration performance is important to ensure occupant comfort and prevent resonance issues. Eurocode 5 provides guidelines for assessing and limiting vibrations in timber structures.
What role does deflection control play in timber beam design?
Deflection control ensures that timber beams do not excessively sag under load, which could lead to serviceability issues or structural failure. Eurocode 5 sets limits for maximum allowable deflection based on beam span and usage.

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.
