Reinterpretation of the Dougong Joint by the use of Parametric Tools and Robotic Fabrication Techniques

Abstract

Traditionally, Chinese architecture was based on the use of timber frameworks as structural system. The Dougong joint is amongst the typical connection typologies, widely applied in the timber heritage buildings in China. Each component of the Dougong (bucket-arch joint) conforms to a strict structural proportion in addition to simple but efficient connection methods between its different components. However, the spread of the structure in modern architecture is limited due to high labour cost. Parametric design and digital fabrication techniques have greatly promoted the development of complex timber structures in recent years, which could be introduced in order to reinterpret the Dougong joint. In continuation of our research on exploring the application of robotic technologies for the fabrication of traditional Chinese timber joints, our paper will investigate the feasibility of the structural logic of the Dougong and how it could be applied in a modern timber framework structure.
