title	Catenary Wooden Roof Structures: Precedent knowledge for future algorithmic design and construction optimisation

summary	The timber industry is expanding, including construction wood product applications such as glue-laminated wood products (R. Sikkema et al., 2023). To boost further utilisation of engineered wood products in architecture, further development and optimisation of related tectonic systems is required. Integration of digital design technologies in this endeavour presents opportunities for a more performative and spatially diverse architecture production, even in construction contexts typified by limited means and/or resources. This paper reports on historic precedent case study research that informs an ongoing larger study focussing on novel algorithmic methods for the design and production of lightweight, large-span, catenary glulam roof structures. Given their structural operation in full tension, catenary-based roof structures substantially reduce material needs when compared with those relying on straight beams (Wong and Crolla, 2019). Yet, the manufacture of their non-standard geometries typically requires costly bespoke hardware setups, having resulted in recent projects trending away from the more spatially engaging geometric experiments of the second half of the 20th century. The study hypothesis that the evolutionary design optimisation of this tectonic system has the potential to re-open and expand its practically available design solution space. This paper covers the review of a range of built projects employing catenary glulam roof system, starting from seminal historic precedents like the Festival Hall for the Swiss National Exhibition EXPO 1964 (A. Lozeron, Swiss, 1964) and the Wilkhahn Pavilions (Frei Otto, Germany, 1987), to contemporary examples, including the Grandview Heights Aquatic Centre (HCMA Architecture + Design, Canada, 2016). It analysis their structural concept, geometric and spatial complexity, fabrication and assembly protocols, applied construction detailing solutions, and more, with as aim to identify methods, tools, techniques, and construction details that can be taken forward in future research aimed at minimising construction complexity. Findings from this precedent study form the basis for the evolutionary-algorithmic design and construction method development that is part of the larger study. By expanding the tectonic system’s practically applicable architecture design solution space and facilitating architects’ access to a low-tech producible, spatially versatile, lightweight, eco-friendly, wooden roof structure typology, this study contributes to environmentally sustainable building.

summary	This paper illustrates a fabrication methodology through which the inherent form of large non-linear timber components was exploited in the Wood Chip Barn project by the students of Design + Make at the Architectural Association’s Hooke Park campus. Twenty distinct Y-shaped forks are employed with minimal machining in the construction of a structural truss for the building. Through this workflow, low-value branched sections of trees are transformed into complex and valuable building components using non-standard technologies. Computational techniques, including parametric algorithms and robotic fabrication methods, were used for execution of the project. The paper addresses the various challenges encountered while processing irregular material, as well as limitations of the robotic tools. Custom algorithms, codes, and post-processors were developed and integrated with existing software packages to compensate for drawbacks of industrial and parametric platforms. The project demonstrates and proves a new methodology for working with complex, large geometries which still results in a low cost, time- and quality-efficient process.

title	Digitally Prefabricated Houses: A Comparative Analysis of Executed Projects
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 967–980
summary	In Brazil, the application of wood in contemporary constructions is concentrated in the south and southeast. However, the entire country has area for cultivation and forest management, which is favorable for expansion in such applications. Wood is capable of absorbing CO2 and consumes little energy in production and manufacturing. During the COVID-19 pandemic, the deficiencies of the building typologies became evident. This research aims to analyze digitally executed prefabricated houses such as Instant House (1), Digitally Fabricated House (2) by Sass, and WikiHouse (3) by Parvin; under the categories of Cardoso (2016): modulation, reversibility, and flexibility. The deductive method was used to investigate assumptions among the three case studies; and grounded in scientific literature to analyze and collect data. In general, the solutions studied enabled customizable systems allied to wood panels, modules, and fittings as generators of architectural form.

summary	This paper reports our current research on automatic generation of houses layouts according to future inhabitant's requirements. For that generation we propose the use of a design method based on shape grammars that encodes light wood frame construction guidelines. Two different implementations for the design system are presently under development. One based on shape grammars supplemented with procedural knowledge and another using a genetic algorithm. Both implementations allow the generation of house layouts that fulfill both the user requirements and the design language.

title	Style and Type in a Generic Shape Grammar - The Case of Multipurpose Chairs
doi	https://doi.org/10.52842/conf.ecaade.2016.2.339

summary	Generic grammars are a means to describe and generate designs in different domains with different abstraction levels. Simple mechanisms can generate a complex variety of solutions within different types, among a coherence of similar styles. This paper describes the process of defining a generic grammar for wood frame multipurpose chair design from two specific grammars that define individual styles of two particular designers. This research is part of a larger one that comprehends the development of a multipurpose chair design tool. The combination of the two specific grammars generates designs from two specific styles, a commons style, a hybrid style and new styles. Results also comprise the characterization of the styles by the analysis of rules and parameters.

title	Robotic Sewing: A Textile Approach Towards the Computational Design and Fabrication of Lightweight Timber Shells
doi	https://doi.org/10.52842/conf.acadia.2016.224
source	ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 224-233
summary	Unlike any other building material, timber has seen numerous innovations in design, manufacturing, and assembly processes in recent years. Currently available technology not only allows architects to freely shape building elements but also to define their micro- or macroscopic material make-up and therefore the material itself. At the same time, timber shells have become a focus of research in wood architecture by rethinking both construction typologies and material application. Their main advantage, however, also poses a challenge to its construction: As the shell is both the load-bearing structure as well as enclosure, its segmentation and the individual segment’s connections become increasingly important. Their complex and often differentiated geometries do not allow for standardized timber joints, and with decreasing material thickness, conventional connection techniques become less feasible. The research presented in this paper investigates textile strategies for the fabrication of ultra-lightweight timber shells in architecture. Specifically, a robotic sewing method is developed in conjunction with a computational design method for the development of a new construction system that was evaluated through a large-scale prototype building.

title	Material computation—4D timber construction: Towards building-scale hygroscopic actuated, self-constructing timber surfaces
source	International Journal of Architectural Computing vol. 14 - no. 1, 49-62
summary	The implementation of active and responsive materials in architecture and construction allows for the replacement of digitally controlled mechanisms with material-based systems that can be designed and programmed with the capacity to compute and execute a behavioral response. The programming of such systems with increasingly specific response requires a material-driven computational design and fabrication strategy. This research presents techniques and technologies for significantly upscaling hygroscopically actuated timber-based systems for use as self-constructing building surfaces. The timber’s integrated hygroscopic characteristics combined with computational design techniques and existing digital fabrication methods allow for a designed processing and reassembly of discrete wood elements into large-scale multi element bilayer surfaces. This material assembly methodology enables the design and control of the encoded direction and magnitude of humidity-actuated responsive curvature at an expanded scale. Design, simulation, and material assembly tests are presented together with formal and functional configurations that incorporate self-constructing and self-rigidizing surface strategies. The presented research and prototypes initiate a shift toward a large-scale, self-construction methodology.

title	Biomimetic Robotic Construction Process - An approach for adapting mass irregular-shaped natural materials
doi	https://doi.org/10.52842/conf.ecaade.2016.1.133

summary	Beaver dams are formed by two main processes. One is that beavers select proper woods for constructing. The other one is that streams aggregate those woods to be assembled. Using this approach to construction structure is suitable for natural environment. In this paper, we attempt to develop a construction process which is suitable for all-terrain construction robot in the future. This construction process is inspired by beavers' construction behavior in nature. Beavers select proper sticks to make the structure stable. We predict that particular properties of sticks contribute gravity-driven assembly of wood structure. Thus, we implement the system with machine learning to find proper properties of sticks to improve selection mechanism of construction process. During this construction process, 3D scanner on robotic arm scans and recognizes sticks on terrain, and then robot will select proper sticks and place them. After placement, the system will scan and record the results for learning mechanism.

title	Robotic Production of Individualised Wood Joints
doi	https://doi.org/10.52842/conf.caadria.2016.559
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 559-568
summary	Modern modular constructions can consist of highly indi- vidualised elements that are produced at nearly the same efficiency as serial manufacturing. This paper focuses on the project “WoodWaves” an Info-Point for the conference World Congress of Timber Engineer- ing, which was designed with this new conception of modularity. The process utilises a robotically operated milling cutter to form block- board panels out of spruce, which make up the multifunctional infor- mation point. The entire object is produced with only sliding dovetail joints. Parametric design methods were developed to automatically adjust each joint to fit the individual conditions. New CAD/CAM in- terfaces, linking design directly with fabrication, enabled the serial production of 108 different shaped elements with a 6-axis robotic arm.
