Structural Timber Design Apr 2026

Timber is unique because its strength varies based on grain orientation (anisotropy) and moisture content.

Structural timber design is a specialized branch of engineering that leverages the natural mechanical properties of wood to create safe, sustainable, and aesthetically pleasing load-bearing systems. Modern design has evolved from simple post-and-beam frames to complex high-rise structures reaching up to 18–24 storeys through the use of Engineered Wood Products (EWPs) . 1.

: Timber is graded (e.g., C16, C24 in Europe) based on density, stiffness, and the presence of defects like knots or cracks. Mass Timber Products :
