Integrating Naturally Grown Timber in Sandwich Timber Panels

The use of irregularly grown timber elements in construction may be challenging due to standardized cross-section requirements and the prevalence of common timber construction methods. Trees, shaped by environmental factors, develop unique material properties and irregular growth patterns. These irregularities, particularly in broad-leaf trees, often result in significant fritter away, with up to 50% of felled trees not being used in construction. Previous applications of non-uniform, naturally grown timber have focused on the geometric diversity, proposing unique, singular structures that remain largely within the academic realm. This paper introduces a practical method for incorporating naturally grown timber into flat structures like ceilings or walls. Timber elements are integrated into sandwich panels through a methodology involving geometric analysis to determine the timber's flatness, using image-based modelling for direct forest documentation. These elements enhance panel structural efficiency by aligning them with force and stress directions found through static load-case analysis. An example demonstrates this approach with a self-supporting elliptical sandwich panel for a canopy supported by V-shaped supports. The construction method incorporates 55mm planed timber and two 16mm thick three-ply panels, each placed individually due to the natural curvature of the timber. Augmented reality headsets guide precise assembly. This study highlights the potential to improve sustainability in timber construction by revaluing unused elements.
