The connections used in any structural system play a signiﬁcant role in deﬁning the form, performance, cost, and aesthetic of an overall design including that of a building.
Topologically Interlocking Joinery (TIJ) is a concept that has been used throughout history around the world to create structures. Examples of TIJ range from complex interlocking topologies such as those used in traditional Japanese wood joinery to simpler elements that are locally held together by kinematic constraints created through the shape and arrangement of the elements.
The construction techniques using TIJs exhibit empirical evidence of efficiency and cultural significance, but their application is limited today. One of the main obstacles in re-introducing the technique is the lack of scientific understanding of the structural behaviour of the joinery systems. Our research aims to develop strategies to uncover such behaviour via state-of-the-art numerical simulations and fabrication methods.
||Disadvantages to overcome:
-> use of digital fabrication
-> use of computational analysis
 advance the understanding of topologically interlocking joinery (TIJ),
 create new computational design methods to exploit TIJ, and
 design and realize new TIJ concepts via modern digital fabrication methods.
