summary Previous research projects (Adel, Agustynowicz, and Wehrle 2021; Adel Ahmadian 2020; Craney and Adel 2020; Adel et al. 2018; Apolinarska et al. 2016; Helm et al. 2017; Willmann et al. 2015; Oesterle 2009) have explored the use of comprehensive digital design-to-fabrication workflows for the construction of nonstandard timber structures employing robotic assembly technologies. More recently, the Robotically Fabricated Structure (RFS), a bespoke outdoor timber pavilion, demonstrated the potential for highly articulated timber architecture using short timber elements and human-robot collaborative assembly (HRCA) (Adel 2022). In the developed HRCA process, a human operator and a human fabricator work alongside industrial robotic arms in a shared working environment, enabling collaborative fabrication approaches. Building upon this research, we present an exploration adapting HRCA to nail-laminated timber (NLT) fabrication, demonstrated through a case study exhibition (Figures 1 and 2).

summary Several research projects (Gramazio et al. 2014; Willmann et al. 2015; Helm et al. 2017; Adel et al. 2018; Adel Ahmadian 2020) have investigated the use of automated assembly technologies (e.g., industrial robotic arms) for the fabrication of nonstandard timber structures. Building on these projects, we present a novel and transferable process for the robotic fabrication of bespoke timber subassemblies made of off-the-shelf standard timber elements. A nonstandard timber structure (Figure 2), consisting of four bespoke subassemblies: three vertical supports and a Zollinger (Allen 1999) roof structure, acts as the case study for the research and validates the feasibility of the proposed process.

summary This paper presents research on the prototyping of multi-agent systems for architectural design. It proposes a design exploration methodology at the intersection of architecture, engineering, and computer science. The motivation of the work includes exploring bottom up generative methods coupled with optimizing performance criteria including for geometric complexity and objective functions for environmental, structural and fabrication parameters. The paper presents the development of a research framework and initial experiments to provide design solutions, which simultaneously satisfy complexly coupled and often contradicting objectives. The prototypical experiments and initial algorithms are described through a set of different design cases and agents within this framework; for the generation of façade panels for light control; for emergent design of shell structures; for actual construction of reciprocal frames; and for robotic fabrication. Initial results include multi-agent derived efficiencies for environmental and fabrication criteria and discussion of future steps for inclusion of human and structural factors.

summary Research investigating water-driven passive actuation demonstrates the potential to transform how buildings interact with their environment while avoiding the complications of conventionally powered actuation. Previous experiments evidence the possibilities of bi-layer materials (Reichert, Menges, and Correa 2015; Correa et al. 2015) and mechanical assemblies with discretely connected actuating members (Gupta et al. 2019). By leveraging changes in weather to power actuated building components these projects explore the use of smart biomaterials and responsive building systems. Though promising the implementation of these technologies requires deep engagement into material synthesis and fabrication. This paper presents the design and prototyping of a rain responsive façade system using chitosan hygroscopic films as actuators counterbalanced by programmed compliant mechanisms. Building on previous work into chitosan film assemblies this research focuses on the development of compliant mechanisms as a means of controlling movement without over-complicated rotating parts.

summary The emerging paradigm of Industry 4.0 is rapidly expanding in the AEC sector, where emergent technologies are offering new possibilities. The use of collaborative robots is enabling processes of advanced fabrication, where humans and robots coexist and collaborate towards the co-creation of new building processes. This paper focuses on setting a conceptual framework and a computational workflow for the design and assembly of a novel type of engineered wood structures. The aim is advancing timber construction through complex tectonic configurations, which are informed by logics of robotic assembly, topology and material optimization, and combinatorial design. Starting from the conceptualization of robotic layered manufacturing for timber structures, this work presents the development of a digital twin applied to the voxel-based design of complex timber structures.

summary The discourse on depleting natural resources and compromised environments have led to extended research on sustainable designs methods, building practices and materials. Beyond the actual performance of building products and components, research on sustainable building increasingly focuses on the long-term effects of the production, application and life cycle of building materials on the natural environment, human inhabitation and quality of life. Computer aided manufacturing technologies play a significant role not only in the transformation of design and building methods, but also in an extended discourse on cultural development. Globally available technologies connect the design and building process to a broad range of long-term ecological factors by creating a correlation between "the emergent political, economical and social processes and … architectural techniques, geometries and organization." Through this interrelationship to economy and culture, technology and its applications are also directly related to notions of place and territory as well as to fundamental ideas of ecology. The collaborative research and design study for an outdoor theater roof structure at the University of British Columbia Malcolm Knapp Research Forest at Maple Ridge, B.C., Canada, focuses on the use of digital media in prefabrication and material optimization. By utilizing small square section timber and minimizing the use of alienating connectors the research on the wood roof structure illustrates the potential of a design culture that seeks innovation in a broader understanding of ecology routed in regional culture, environmental conditions, economy and tradition. Labor intensive manufacturing techniques are redefined aided by computer controlled machines and virtual modeling of complex geometries is translated into simple operations. The result is a more sensible and accurate response to the place’s demands. In order to generate innovative design interventions that make a constructive long-term contribution to the preservation, maintenance and evolution of the environment, design needs to be based on a comprehensive understanding of its context and the distinctive qualities of the materials used. Following the example of the outdoor roof structure, this paper aims to define innovative design as work that resonates at the intersection of the fields of technology, material science, manufacturing processes, techniques of assembly and context that constitute the expanded context or complex ecology that projects need to engage. It is in design research studies like for the outdoor theater roof structure with focus on CNC wood fabrication technologies that the common design and building discourse is put to question, boundaries are explored and expanded and the collective understanding is improved towards ecological design.

title Catenary Wooden Roof Structures: Precedent knowledge for future algorithmic design and construction optimisation
doi https://doi.org/10.52842/conf.ecaade.2023.1.611
source Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 1, Graz, 20-22 September 2023, pp. 611–620
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.

title Innovative CNC Timber Framing - Technology and Cultural Expression
source International Journal of Architectural Computing vol. 5 - no. 3, pp. 469-486
summary he design-build project for the outdoor theater roof structure at the UBC Malcolm Knapp Research Forest at Maple Ridge, British Columbia, explores technical, spatial, and cultural aspects of CNC wood fabrication. References for the project are technological innovation and formal expression of contemporary wood structures. The roof project illustrates how spatial concepts are informed by the logic of fabrication and methods of assembly. A reciprocal relationship between technology, space, and locale suggests that the introduction of new technology coincides with new spatial concepts. Innovative design in this project is defined as work that resonates at the intersection of the fields of technology, material science, manufacturing processes, and techniques of assembly that constitute the expanded context that projects need to engage. It is through collaborative design research on CNC wood fabrication technologies that common design and building practice is put into question, and boundaries are explored and expanded.

summary This paper describes a framework for discrete computational design and fabrication in the context of automation. Whereas digital design and fabrication are technical notions, automation immediately has societal and political repercussions. Automation relates to industrialization and mechanisation—allowing to historically reconnect the digital while bypassing the post-modern, deconstructivist, or parametric decades. Using a series of built prototypes making use of timber, this paper will describe how the combined technologies of automation and discreteness enable both technical efficiencies and new architectural interest. Both projects are based on timber sheet materials, cut and folded into larger elements that are then assembled into functional structures. Both projects are also fragments of larger housing blocks. Discrete building blocks are presented from a technical perspective as occupying a space in between programmable matter and modular prefabrication. Timber is identified as an ideal material for automated discrete construction. From an architectural perspective, the paper discusses the implications of an architecture based on parts that remain autonomous from the whole.

title Structural Composite Members in Architecture Fabricated by CAD/CAE/CAM Technology
source Harvard University
summary The doctoral research in this dissertation is aimed at exploring new materials and innovative methods for fabricating complex-shaped buildings, which have surfaced as a prevailing trend in architecture today. Over the past few years, the field of architecture has witnessed revolutionary changes in design. The recent completion of Frank O. Gehry's new Guggenheim Museum in Bilbao, Spain, brought unprecedented attention to complex-shaped, non-conventional designs and its influence on the global architectural trend has been immense. In following these latest trends, the author was drawn to the issues concerning construction materials and methods that are being currently adopted in realizing these complicated designs. It is perhaps inevitable that the traditional steel construction methods, suitable for use in the conventional linear shapes, face tremendous challenges and limitations in building such complex-shaped designs. In the author's opinion, the next step to go from here is to seek joint efforts between the architectural field and the engineering field to search for a new methodology which will best serve the contemporary design style. This research first focused on examining the problems that traditional methods pose for the new complex-shaped buildings. Paying attention to Gehry's recent projects, the author was able to identify major difficulties in association with representing and constructing these complicated shapes, mainly in terms of the relationship between the primary structure and the envelope surface. The second part of the research moved on to proposing a new alternative to the traditional methods, by utilizing polymer composite materials (PCM) as construction material and employing advanced Computer-Aided Design (CAD)/Computer Aided Engineering (CAE)/Computer-Aided Manufacturing (CAM) technologies. More specifically, the author has attempted to present effective theories in support of the two following ideas: (1) circular tubes made of PCM are the most promising alternative to regular steel members, especially steel tubes, to follow the envelope surface of the complex shaped building. (2) state-of-the-art CAD/CAE/CAM technologies are the most essential tools to achieve the geometrical and functional quality of the proposed new material. In the second phase, the primary focus of the quantitative approach was on fabricating an experimental model (1:1 scale prototype) called “ a unit of boundary structures”, the basic unit of structure system that wraps a complex-shaped building's entire territory .

summary This paper describes the development of the StretchPLAY prototype as a part of the Social Sensory Surfaces research project, focusing on the design of tactile and responsive environments for children with Autism Spectrum Disorder (ASD). The project is directed specifically at issues with sensory processing, the inability of the nervous system to filter sensory input in order to indicate an appropriate response. This can be referred to as a “traffic jam” of sensory data where the intensity of such unfiltered information leads to an over-intensified sensory experience, and ultimately a dis-regulated state. To create a sensory regulating environments, a tactile structure is developed integrating physical, visual and auditory feedback. The structure is defined as a textile hybrid system integrating a seamless knitted textile to form a continuous topologically complex surface. Advancements in the fabrication of the boundary structure, of glass-fiber reinforced rods, enable the form to be more robustly structured than previous examples of textile hybrid or tent-like structures. The tensioned textile is activated as a tangible interface where sensing of touch and pressure on the surface triggers ranges of visual and auditory response. A specific child, a five-year old girl with ASD, is studied in order to tailor the technologies as a response to her sensory challenges. This project is a collaboration with students, researchers and faculty in the fields of architecture, computer science, information (human-computer interaction), music and civil engineering, along with practitioners in the field of ASD-based therapies.

title Toward a Behavioral Design System: An Agent-Based Approach for Polygonal Surfaces Structures
doi https://doi.org/10.52842/conf.acadia.2015.161

summary The following research investigates the development of an agent-based design method as an integrative design tool for polygonal surface structures. The aim of this research is to develop a computational tool that self-organizes the emergence of polygonal surface structures from interaction between its constitutive lattices. This research focuses on the ethological level of morphogenesis that is relevant to the animal or insect societies, whereby agents mediate the material organizations with environmental aspects. Meanwhile, behavior-based approaches are investigated as a bottom-up system to develop a computational framework in which the lower-level features constantly interact. The lower-level features such as material properties (e.g., geometric descriptions) are abstracted into building blocks or agents to construct the agent’s morphology. The abstracted principles, which define the agent’s morphology, are aggregated into a generative tool to explore the emergent complexities. This exploration coupled with the generative constraint mechanisms steers the collective agents system toward the cloud of solutions; hence, the collective behaviors of agents constitute the polygonal surface structures. This polygonal system is a bottom up approach of developing the complex surface that emerges through topological and topographical interaction between cells and their surrounding environment. Subsequently, the integrative system is developed through agent-based parametric modelling, in which the knowledge-based system as a top-down approach is substituted with the agent system together with its morphological features and significant behaviors.

title Structural design based on performance applied to development of a lattice wind tower

summary This paper studies the process of parametric and algorithmic design, integrating structural analysis and design for the generation of complex geometric structures. This methodology is based on the Performative Model, where the shape is generated using performance criteria. In the approach, the development of complex structures is only possible by reversing the process of thinking to generate the form with established parameters for geometry, material and loading aspects. Thus, the structural engineer no longer only participates in the evaluation phase but also appears in the early stages, creating a process of exploration and production of common knowledge among architects and engineers. To research performance-based design, the development of a conceptual lattice for a wind tower is proposed. Thus, a system is made to generate geometries using Rhinoceros software, the Grasshopper plugin, and the VB programming language, integrated with stress analysis through the Scan & Solve plugin.

summary Based on our current daily rate, 85,410 hours is the average amount of time that an adult in the United States will spend on their phone in a lifetime (Howarth 2023). This is time spent texting, tweeting, emailing, snapping, chatting, posting, and interacting with an interface which each of us carry in our pocket. Kelly Dobson explains, “We psychologically view the cell phone as an extension of our bodies, which is why when you accidentally forget it or leave it behind you feel you have lost apart of yourself” (2013). In reality, this device is just one of many technologies which affect our relationship with our bodies and the physical world. Additionally, Zoom meetings, social media networks, on-line shopping, and delivery robots, all increasingly detach our bodies and our senses from our everyday experiences and interactions. In response to digital culture, Liam Young writes, “Perhaps the day will come when we turn off our target ads, navigational prompts, Tinder match notifications, and status updates to find a world stripped bare, where nothing is left but scaffolds and screens” (2015). Make no mistake; the collection of projects shared in these field notes is intended to be a counterpoint to such a prophesied future. However, the intent is not to try to compete with technology, but rather, to consider the built environment itself as an interface, encouraging interaction through feedback and responsivity directly related to human factors, finding ways to re-engage the body through design.

summary This paper is a critical review on advantages and disadvantages of contemporary digital architecture, in retrospect to Vladimir Shukhov's design techniques, applied in the early 20th century. After investigating Shukhov's structural systems, this paper explores the relationship between performance and form, questioning the necessity of high-complexity structures. It will present unpublished archive material of his early work and stimulate a valuable discussion by comparing it with contemporary projects designed by renowned architects. The study on Shukhov focuses on his tessellation method of double-curved surfaces using simple standardized elements. The study of present digital approaches revolves around leading architects using computational tools (e.g. Foster and Partners, Buro Happold and Arup), who have materialized high complexity structures composed by irregular units. Our findings highlight advantages and disadvantages of contemporary computational approaches.

title Assisted construction of non-standard wooden walls and envelope structures by parametric modeling
source The next city - New technologies and the future of the built environment [16th International Conference CAAD Futures 2015. Sao Paulo, July 8-10, 2015. Electronic Proceedings/ ISBN 978-85-85783-53-2] Sao Paulo, Brazil, July 8-10, 2015, pp. 328.
summary We introduce a parametric modeling method in the field of computer-aided architectural conception, which aims to produce non-standard wooden walls and envelopes with CNC machinery. This method explores the application of polygonal cellular structures (as patterns) on facade and envelope interventions for new and old projects. We innovate by bringing the 3D production environment complexity into the conception model to improve the production of manifold woodworking items by CNC (Computer Numerical Control) 3D fabrication. A recent experimentation, tests the entire workflow from parametric modeling to production of two full-scale prototypes. The results prove the range of inputs offered by the method to be functional, though it needs various improvements in order to optimize parametric modeling and digital fabrication procedures. Future research will focus on treating a wider range of joints via parametric modeling and deal with joint creation regardless wall deformation to expand the morphological approach of non-standard wooden walls design.

summary With an exponential increase in the possibilities of computation and computer-controlled fabrication, high density information is becoming a reality in digital design and architecture. However, construction methods and industrial fabrication processes have not yet been reshaped to accommodate the recent changes in those disciplines. Although it is possible to build up complex simulations with millions of particles, the simulation is often disconnected from the actual fabrication process. Our research proposes a bridge between both stages, where one drives the other, producing a smooth transition from design to production. A particle in the digital domain becomes a drop of material in the construction method.The architect's medium of expression has become much more than a representational tool in the last century, and more recently it has evolved even beyond a series of rules to drive from design to production. The design system is the instruction itself; embedding structure, material and tectonics and gets delivered to the very end of the construction chain, where it gets materialised. The research showcased in this paper investigates tectonic systems associated with large scale 3D printing and additive manufacturing methods, inheriting both material properties and fabrication constraints at all stages from design to production. Computational models and custom design software packages are designed and developed as strategies to organise material in space in response to specific structural and logistical input.Although the research has developed a wide spectrum of 3D printing methods, this paper focuses only on two of the most recent projects, where different material and computational logics were investigated. The first, titled Filamentrics, intends to develop free-form space frames, overcoming their homogeneity by introducing robotic plastic extrusion. Through the use of custom made extruders a vast range of high resolution prototypes were developed, evolving the design process towards the fabrication of precise structures that can be materialised using additive manufacturing but without the use of a layered 3D printing method. Instead, material limitations were studied and embedded in custom algorithms that allow depositing material in the air for internal connectivity. The final result is a 3x2x2.5m structure that demonstrates the viability of this construction method for being implemented in more industrial scenarios.While Filamentrics is reshaping the way we could design and build light weight structures, the second project Microstrata aims to establish new construction methods for compression based materials. A layering 3D printing method combines both the deposition of the binder and the distribution of an interconnected network of capillaries. These capillaries are organised following structural principles, configuring a series of channels which are left empty within the mass. In a second stage aluminium is cast in this hollow space to build a continuous tension reinforcement.

summary Voxelbeam explores precedents in the optimization of architectural structures, namely the Sydney Opera house Arup beam. The authors research three areas crucial to conceiving an innovative contemporary reinterpretation of the beam: A shift in structural analysis techniques from analytical to numerical models such as topology optimization, the fundamental differences between digital and analog representations of structural forces, and the translation of structural analysis data into methods for digital fabrication. The research aims to re-contextualize the structural beam within contemporary digital platforms, explores the architectural implications of topology optimization, and proposes two fabrication strategies based on the analysis results – including automated off-site pre-casting and multi-material 3d printing.

summary Architects have a renewed interest in surface structures and the renewable resource of wood, along with advanced digital design, analysis and machining techniques, offers a way of manifesting these forms. Wood is easily machined and has bending properties that lead to the ability to form curves. This paper looks at the properties of wood, informing design through its material characteristics. The research presented here contributes to this discourse through the development of large scale timber shell structures. We propose hyper efficient structures made out of laminated wood products to provide a new solution to long span construction while satisfying the demand for agency in form generation.

title Digital Fabrication Methods of Composite Architectural Panels for Complex Shaped Buildings
doi https://doi.org/10.52842/conf.caadria.2015.703
source Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 703-712
summary Composite materials have been explored in architecture for their high performance characteristics that allow customization of functional properties of lightness, strength, stiffness and fracture toughness. Particularly, engineering advancements and better understanding of fiber composites have resulted in growing applications for architectural structures and envelopes. As most developments started outside the realm of architecture such as automobile and aeronautical industries, there is need to advance knowledge in architectural design to take advantage of this new technology. In this paper, the authors introduce preliminary results of new digitally driven fabrication methods for fiber-reinforced composite sandwich panels for complex shaped buildings. This research examined the material properties, manufacturing methods and fabrication techniques needed to develop a proof of concept system using off-the-shelf production technology that ultimately can be packaged into a containerized facility for on-site panel production. Experiments focused on developing a digitally controlled deformable mold to create composite relief structures for highly customized geometrical façade components. Research findings of production materials, methods, assembly techniques, are discussed to offer insights into novel opportunities for architectural composite panel fabrication and commercialization.
