Gluelam structural member and a method of producing such a gluelam structural member

A structural member in the form of a gluelam beam having an elongate cross section presenting a horizontally oriented short side and a predetermined main bending direction, which is perpendicular to the short side, comprising:

• a plurality of glued-together wood lamellae, each having a lamella cross section which is parallel with a cross section of the structural member 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,
• wherein the lamellae are formed as radial sections of a log,
• wherein the lamellae present cross sections which are triangular or trapezoidal and present a respective planar major base surface that is formed at a radially outer part of the log,
• wherein the planar major base surfaces are perpendicular to the main bending direction, and wherein the planar major base surfaces are parallel to the short side of the cross section,
• wherein the structural member comprises at least two glued-together layers of lamellae that are arranged such that the planar major base surfaces of a pair of immediately adjacent lamellae face opposite directions, and,
• wherein a layer that is positioned closer, as seen in the main bending direction, to an outer face of the structural member presents a smaller number of annual rings than a layer that is positioned further away from the outer face.
