Folding wood: nvestigating architectural opportunities of folded plate principles in timber structures

Abstract

The concept of the folded plate has existed within the field of architecture and engineering for close to a century. However, one seldom encounters folded plate structures in the built environment. In theory, the folded plate is an efficient way of enclosing large volumes using a relatively small amount of material. Nevertheless, in architectural design, there seems to be a multitude of challenges that prevents this theory from becoming reality. This thesis investigates how the folded plate principles can be pushed beyond perfectly symmetrical shapes to gain spatial values. Aspects such as inclusion of apertures, space division and shell construction are discussed on a conceptual level. Moreover, this thesis looks at the use of Cross Laminated Timber (CLT) in folded plate structures and how these can be designed using digital design tools. The work departs from existing literature and built examples and uses a combination of physical and digital modeling to further explore the folded plate as a structural and architectural concept. Fundamental principles found in origami are used to initiate the discussion on folded geometry. To contextualize findings and ideas derived from this research and to suggest an expanded use of folded plates, a design proposal for a public building in central Gothenburg was produced. Finally, conclusions drawn from the research done relating to asymmetry as well as additional aspects are presented. The practical and architectural significance of design choices made in the final proposal are discussed in relation to knowledge gained from this research.
