Abstract:
The present disclosure provides a structural member (10), such as a beam, a stud or a joist, presenting a predetermined bending direction (B). The structural member comprises a plurality of glued-together wood lamellae (20a, 20b), each having a lamella cross section which is parallel with a cross section of the structural member (10) and a longitudinal direction which is parallel with a longitudinal direction of the structural member and with a principal grain direction of the wood lamellae (20a, 20b). In the structural member, the lamellae (20a, 20b) are formed as radial sections of a log and present cross sections which are triangular or trapezoidal and present a respective base surface (bs1) that is formed at a radially outer part of the log. The lamellae (20a, 20b) are arranged as at least one layer in which base surfaces (bs1) of a pair of immediately adjacent lamellae (20a, 20b) face opposite directions. The base surfaces (bs1) are perpendicular to the bending direction (B).
