Naturally grown timber elements for load-bearing structures: methods for modeling, structural design, and construction.

RWTH Publications (RWTH Aachen)

Abstract

This dissertation investigates the potential of naturally grown timber as a structural material, focusing on its geometric and mechanical characteristics to inform architectural design. Contrary to the conventional approach of designing first and then sourcing materials, this research adopts an inverse methodology: it begins by analyzing inherent natural design patterns and subsequently applies these insights to the conception of architectural structures. This study bridges multiple disciplines to propose a methodology that integrates tree analysis, growth pattern interpretation, scanning, geometric modeling, material characterization, and structural design across scales—from individual growth behavior to full-scale assemblies. Computational tools are employed to simulate the structural behavior of the material, enabling performance-driven design decisions that account for fabrication feasibility and resource availability. This work contributes a multi-scalar analytical framework and a set of custom joinery strategies tailored to irregular timber geometries. Structural optimization methods are developed for both element positioning and connection design. Through case studies, prototypes, and workshops, the methodology is tested in academic and applied contexts. Overall, this dissertation promotes a material-driven design philosophy, demonstrating how raw timber can serve as a viable and sustainable alternative for load-bearing architectural applications.
