Timber structures — Mechanically laminated timber — Production and qualification requirements

Scope

Mechanically laminated timber (MLT) is an engineered wood product that is intended for structural applications subjected to out-of-plane loading. The MLT layups contain lumber laminations connected to parallel to each other along adjacent laminations on the wide face using either steel metal or wooden fasteners, with the laminations loaded on edge. The fibre directions of all laminations within MLT are parallel to each other. The proposed standard will address the production and qualification requirements for MLT. It will provide qualification paths for prescriptive MLT products with standard layups and custom MLT products with proprietary layups.
