TRÆbjælker is a calculation program designed for engineers, architects, and carpenters who need quick and accurate calculations for beam constructions. Whether you are on-site or in the office, this app allows you to perform calculations with ease.

How does TRÆbjælker work?

TRÆbjælker is specifically designed for dimensioning floor beams and cross beams in single-family houses, summer houses, and townhouses. Additionally, the program can also handle calculations for roof trusses, window lintels, and ridge beams.

The program is tailored for both construction timber and laminated timber, with all calculations based on Eurocode 5 (EC5) standards. However, it is important to note that the app does not perform checks for resistance against wind suction on roofs.

Types of beam calculations:

TRÆbjælker calculates beam dimensions and deflection for:

• Floor beams in multi-story buildings
• Cross beams under floor beams
• Roof trusses with angles ranging from 5 to 45 degrees
• Lintels above facade openings
• Ridge beams and cross beams under roof trusses

The program is user-friendly and requires only the selection of timber quality, beam width, and input of relevant building dimensions. Calculations can be quickly sent via email or message, allowing for easy storage or printing as documentation for construction projects.
