Topology Optimization of Spatial Timber Structures, Zurich, 2015
Research Stay Asbjørn Søndergaard
Topology optimization is a widely applied method for creating high-performance structural designs in automotive, naval and aeronautic industries. Within civil engineering, this technique provides an outlook for enabling substantial reductions in material consumption and structural design innovation, hereby indicating a significant potential for lowering the environmental impact of construction. However, the application of topology optimization within the domain of architectural design poses critical challenges. The main inhibitor for larger scale implementation is the complexity of efficiently constructing topology optimized structures. The research project addresses this challenge by developing optimization methods targeted at spatial timber structures, and by investigating means of direct realization of optimized timber topologies via computational node-geometry rationalization, geometry-based generation of spatial assembly motion, and robotic timber fabrication strategies.

The research project builds on preliminary findings of the ongoing SNSF NRP 66 research project
Additive Robotic Fabrication of Complex Timber Structures conducted in collaboration with the Bern University of Applied Sciences Architecture, Wood and Civil Engineering.
