Knowledge Base Repository
In addition to research papers, the Design Society is developing several valuable resources for those interested in the study of design. These include a repository of PhD theses, a library of case studies and transcripts of design activities, and an archive of our newsletters. Please note that these resources are accessible exclusively to Design Society members.

Abstract:
Trusses represent an economical, rigid and effective lightweight construction method. However, the connecting parts (nodes) between the struts are a design challenge, especially in highly optimized trusses. Several struts with different geometries (diameter, cross-sections) must be connected at any spatial angle in one point in a manner that is suitable for the load. The use of fibre-reinforced materials for the struts is common practice, for the nodes, metals are usually used. However, these do not exploit the full lightweight construction potential of the truss. The proposed method allows the design of truss nodes using fibre-reinforced materials and additive manufacturing, while taking into account the geometric boundary conditions of the connection points for the struts.
