Generative Design for Folded Timber Structures

Abstract

Folding structures belong to the group of lightweight structural systems, which often consist of polygonal elements like triangles or quadrangles. Folding structures whose construction is made out of cross-laminated timber (CLT) panels represent an innovative step in the timber industry, which has many advantages. CLT panels can be used simultaneously as supporting elements and as finishing building envelopes. There are many prefabrication possibilities, high efficient material consumption, low production and assembly costs, and it has environmental advantages over conventional materials used for folding structure like concrete, metal or glass. CLT folding structures are not sufficiently explored. One of the reasons may lie in the fact of limited design possibilities, which includes the specificity of CLT capacity. Another reason is maybe the inability to use standard wooden connectors to transfer the forces along the thin linear edges where the panels are supported. The aim of this paper is to present design possibilities through parametric modelling using the characteristics of CLT. Using the example of a wooden theatre stage we will present results of our research.

Implementation of Building Information Modeling Technologies in Wood Construction: A Review of the State of the Art from a Multidisciplinary Approach

“…Any kind of sustainable information such as LCA (life cycle analysis) standards or others are not accepted in common CAD software. Visual programming languages for creating more sophisticated models are also useful [110,111], and advanced parametric software such as Grasshoper [112], Rhino, Generative Components [113] are being used to create parametric buildings and components. In the case of Rhino, the research conducted by [114] developed a plug-in for the 3D modelling software Rhinoceors at the Institute for Digital Economy in the construction and wood industries (IdBH), which avoided complex node intersections and reduced fabrication complexity for the manufacture flow of architectural forms from wood.…”

Taxonomy supporting design strategies for reuse of building parts in timber-based construction

“…In the same study, it was found that the use of timber frames in multistorey buildings could reduce embodied carbon by 48% in comparison with steel and by 19% compared to concrete as the principal structural material. Moreover, timber is renewable and lightweight, with good thermal properties and a low carbon footprint (Svatoš-Ražnjevi c, 2022;Hens et al, 2021;Kunic et al, 2021;Ostrowska-Wawryniuk, 2021;Bukauskas et al, 2019;Stavric and Bogensperger., 2015;Daerga et al, 2014;Leskovar and Premrov, 2012;Weinand, 2009). Additionally, timber provides an agreeable indoor microclimate and has positive effects on the occupants of the building, while reducing stress (Ostrowska-Wawryniuk, 2021;Tarin et al, 2019;Leskovar and Premrov, 2012).…”

Parametric design of developable structure based on Yoshimura origami pattern

“…The Huffman grid origami pattern was used in the roof of a sketch building at the Hanover World Expo in 2000 and for the gate of the 2002 Turin Winter Olympics. Stavric et al [7] constructed an architectural sketch using the expansion pattern of Miura-ori origami and analyzed the bearing capacity of the structure by using finite element software. Falk et al [8] designed a temporary church in Saint Loup, France, and optimized the lighting of the building through Autodesk Ecotect Analysis software, which was also based on the Miura-ori origami pattern.…”
