M-CDC workshop results: Reciprocal Structures

The elective course on digital woodwork aimed at the development of an innovative construction, based on self-supporting, reciprocal systems.

The reciprocal frame is a roof structure where each beam both supports and is supported by other beams in the roof structure. A minimum of 3 beams is required to create a reciprocal frame roof. As each beam supports the next in a reciprocal manner no internal support structure is required.  Only the outer end of each beam requires support, which will normally be a post used for the wall or the foundation.

Throughout the last years we have already seen promising advancements and applications in digital woodwork, such as CNC-technology and robotic manufacturing. Hence, the Master students took a closer look at the computational processes introduced to gain an in-depth understanding of the conditions and constraints as a starting point for their own design strategy. The four-day intensive program included both computational form-finding strategies in the design process as well as construction principles and digital fabrication technologies for the 1:1 realization of a reciprocal roof structure. Michael Knauß, founding partner of Zurich based office ROK and expert in digital fabrication, conducted the workshop during the Detmolder Räume (Detmold Spaces), a creative week of experimentation in interdisciplinary work on our campus.
