Use of Timber in Tall Multi-Storey Buildings (Structural Engineering Documents)

Since the dawn of civilization, timber has been a primary material for achieving great structural engineering feats. Yet during the late 19th century and most of the 20th century it lost currency as a preferred material for construction of large and tall multi-storey building superstructures. This Structural Engineering Document (SED) addresses a reawakening of interest in timber and timber-based products as primary con- struction materials for relatively tall, multi-storey buildings. Emphasis throughout is on holistically addressing various aspects of performance of complete systems, refl ecting that major gaps in knowhow relate to design concepts rather than technical information about timber as a material. Special con- sideration is given to structural form, fi re vulnerability, and durability aspects for attaining desired building performance over lifespans that can be centuries long.
