Topological Interlocking structures - Inha University workshop
Topological interlocking (TI) is a particular case of masonry in which simple elements are arranged so that an entire structure is held together by kinematic constraints inflicted through the form and the mutual arrangement of the elements. During the 20th century, numerous attempts to employ the notion of TI in architecture have been made. However, despite its structural and economic potential advantages, topological interlocking is rarely used in practice due to the complex geometry and structural behavior of its building blocks, which are challenging to design, simulate and fabricate. Recent developments in digital design and fabrication technologies significantly reduce these limitations in the design and fabrication of complex architectural forms.
The workshop re-examined the potential of employing the notion of topological interlocking in architecture. It focused on generating new TI structural systems and employing them in a case study design. The geometric exploration was based on using a new grasshopper plug-in that generated 2D and 3D interlocked patterns and elements developed in the T_Code laboratory. Participants were asked to generate unique TI formations using the plug-in and intervene/develop further/modify the basic TI system to fit various architectural uses.
As a case study, the workshop concentrated on developing a new structural system and design for a 200sq”m shade structure/pavilion for an external lecture/performance made from the interlocking element. The suggested structure was made solely from TI elements without external joints or mortar/glue.
