Timber Beam Calculator to EC5

Verified by the CalcTree engineering team on July 2, 2024
﻿
This calculator designs timber bending members, commonly referred to as rafters and joists, by ensuring the beam meets flexural, shear, bearing, deflection and vibration requirements. The calculator takes into account a notch at the support.
All calculations are performed in accordance with:
BS EN 1995-1-1 2004 A2 2014 Design of timber structures - General rules. This code is typically referred to as "Eurocode 5" or "EC5". 
BS EN 1995-1-1 2004 A1 2008 UK NA to Design of timber structures - General rules. This is the UK National Annex to Eurocode 5.
