Abstract

The Dougong (brackets set) is a traditional Chinese capital used to transfer the load of the roof to a column. It is known for its anti-seismic properties, sustainability, and cultural significance. This paper introduces a framework for parametric design and robotic fabrication of the Dougong, thus it can be utilised in contemporary architecture. The framework incorporates topology optimisation, voxelisation, multi-objective optimisation and robotic assembly and is verified by designing and assembling a timber frame column out of Dougong units. Our findings highlight the potential of utilising the Dougong in contemporary design as well as a strategy to reduce the tolerances of robotically assembled tenon-mortise elements.
