Flitch beams can be used for lintels, attic beams and other situations where solid timber beams are not strong enough or stiff enough to support design loads adequately. A bolted steel flitch beam is a vertically laminated beam consisting of timber stringers and steel plates bolted together. This Engineering Guidance Document - GD9 - provides a design for a flitch beam which consists of two identical timber members with one steel plate bolted between them. Flitch beams can be used for lintels, attic beams and other situations where solid timber beams are not strong enough or stiff enough to support design loads adequately.

Eurocode 5 does not provide a specific design method for flitch beams, but the method given is based on the principles in Eurocode 0, Eurocode 3 and Eurocode 5.

A design example to BS 5268, based on this document, can be found in TRADA Technology’s Timber frame housing: UK Structural recommendations. TRADA’s flitch beam design software (free to TRADA members in the ‘lite’ version) is recommended for regular designers of these components to BS 5268.
