| summary |
The traditional craft technique of “wood kerfing” allows the bending of flat boards into 3D-geometry through a series of incisions (“kerfs”), thereby lending wooden structures a soft and pliable aesthetic. This method offers rich design potentials, driven by the interplay of material properties and geometric principles of the incisions. The incisions naturally weaken the wood, resulting in reduced material stiffness, which often poses a significant challenge to application kerf-bent timber structures at building element scale.
This work addresses the dual challenge of achieving both soft aesthetics and load-bearing capacity. We explored design opportunities of kerfed wood in conjunction with a structural application through a 1:1 scale demonstrator with a footprint of 12 m2. To enhance fabrication efficiency, traditional craftsmanship was combined with state-of-the-art CNC technology, significantly streamlining the complex manufacturing process. Additionally, we developed strategies to gain a better understanding of the structural behavior of "soft" wood materials through FEM simulation. This approach allowed us to correlate the precise digital design- and simulation-models with - sometimes unpredictable - physical outcomes, exploring the tension field between material agency, geometry and structural performance. |
