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

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	Gridshell Tectonics: Material Values Digital Parameters
doi	https://doi.org/10.52842/conf.acadia.2008.118
source	Silicon + Skin: Biological Processes and Computation, [Proceedings of the 28th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) / ISBN 978-0-9789463-4-0] Minneapolis 16-19 October 2008, 118-125
summary	This paper begins with a simple proposition: rather than mimicking the geometric structures found in nature, perhaps the most effective modes of sustainable fabrication can be found through understanding the nature of materials themselves. Material becomes a design parameter through the constraints of fabrication tools, limitations of material size, and most importantly the productive capacity of material resistance—a given material’s capacity and tendencies to take shape, rather than cutting shape out of material. ¶ Gridshell structures provide an intriguing case study to pursue this proposition. Not only is there clear precedent in the form-finding experiments of Frei Otto and the Institute for Lightweight Structures, but also the very NURBS based tools of current design practices developed from the ability of wood to bend. Taking the bent wood spline quite literally, gridshells provide a means that is at once formally expressive, structurally optimized, materially efficient, and quite simply a delight to experience. The larger motivation of this work anticipates a parametric system linking the intrinsic material values of the gridshell tectonic with extrinsic criteria such as programmatic needs and environmental response. ¶ Through an applied case study of gridshells, the play between form and material is tested out through the author’s own experimentation with gridshells and the pedagogical results of two gridshell studios. The goal of this research is to establish a give-and-take relationship between top-down formal emphasis and a bottom-up material influence.

summary	The experimental work of Antoni Gaudí and Frei Otto have been the precedents of what is currently called form-finding, a methodology based on rules and physical forces of nature that promotes principles of transformation as a result of the relationship between form, material and structure. This text shows the first results of the research titled as Form-finding methodology as strategy for formative research in industrial design education, with an empirical-analytical approach through action-research based method and using collaborative-participatory tools. As a result of the analysis of different cases in the first stage of the research, a basic methodological proposal is made, this methodological proposal is aimed to find new research possibilities for the identification of morphological characteristics to be used in design projects in the early creative phases (ideation and experimentation); the methodological proposal stages are the following: selection of technique, design of the experimentation, experimentation, analysis and discussion.

title	Pattern Language and Embedded Knowledge in Building Information Modeling
doi	https://doi.org/10.52842/conf.ecaade.2007.457
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 457-464
summary	When Christopher Alexander (1977), trained both as a mathematician and an architect, published his seminal work “The Pattern Language” in the 1970’s and introduced the concept of “pattern language”, computers were still in their infancy, CAD did not exist as we know it today, and computer information modeling was not even in the radar screen of researchers. Design communication simply meant manual drafting. With the concept of ‘pattern language” (http://www.patternlanguage.com/), Alexander proposed a systematic method for dealing with complexity, which proved itself to be more relevant than ever in the digital age. The concept is often cited by computer scientists as a precursor to object oriented modeling. This study explores the potential of “pattern language” for structuring building information and design knowledge within the framework of the recent developments in building information modeling (BIM). In this article, comparisons to the approach taken by the software engineering industry who embraced the idea of “patterns” as a systematic way to software development are also made. While Alexander’s pattern language proposes a method with which the designer can incorporate his/her experiences and design vision systematically into the process of designing, software industry’s approach to patterns describes a method for providing problem and solution patterns (i.e. prototypes) that can be used repeatedly during software development. There is obviously a significant difference between the original intent of the “pattern language” and the way it was later used in other fields including software engineering and business solutions. At the cross section of architectural design and software engineering, Building Information Modeling (BIM) software can benefit from carefully incorporating a combination of these two approaches into its structure as patterns.

title	A Primitive Parametric
doi	https://doi.org/10.52842/conf.caadria.2014.893
source	Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 893–902
summary	This paper describes the products of an exhibition organized by the authors that speculatively reconstructed the ‘long history’ of Architectural Biology to recover the cultural potential of biological metaphors in contemporary architecture. The extended historical timeline of the show spanned from the second half of the nineteenth century to the present. However, in contrast to previous shows that have isolated modern architects’ interests in the formalist principles of biology, this show examined the formal and cultural prerogatives of modern architects in tandem with one another. This historical framework encouraged the speculative analysis of the social and political relevance of contemporary claims, which inherently challenges the ahistorical bias of the postcritical debates that emerged in the new millennium. Widening our gaze to examine the ‘long history’ of biological metaphors in architecture enabled us to recuperate the cultural significance that biological references have accrued within the discipline of architecture. This disciplinary history promises to repair the historical amnesia that has beset contemporary architects who limit their analysis of biology to formalist principles of design. A key component of the exhibit was the conceptual pairing of the ‘primitive’ (cultural) concerns of nineteenth-century figures with the ‘parametric’ (formal) concerns of postwar and contemporary architects. Using Gottfried Semper as a representative figure for the former position, we reinterpreted the inherent cultural meaning of postwar and contemporary architectural works, including those completed by Frei Otto, Achim Menges, Lars Spuybroek, SHoP, and Evan Douglis. The material potential of this approach was expressed in the making of analytical maps, digital models, and conceptual drawings that explored the latent ‘primitive’ themes of contemporary ‘parametric’ designs.

source	Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 2, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 145-152
summary	This paper examines how designers can invigorate designs with a sense of liveliness and indeterminacy through manipulation of pliable materials. Two approaches to material manipulation are defined and juxtaposed in the paper: The control associated with Frei Otto's elegantly tensioned membranes and the noise associated with Sigurd Lewerentz's intensely material brick walls. These historical approaches become pertinent in relation to current opportunities offered by material simulation software in architecture. Simulation may be used to increase control over the materialization of design, but is at the same time a way to introduce the noise of real-time, real-world experiments into digital design. The paper presents this discussion in parallel with documentation of the research project 'Erratic', a recent installation carried out by the authors' practice Norell/Rodhe. Constructed from polyurethane cold foam, the project combines analogue experiments with digital simulations to target architectural qualities like mass, figuration and relief.

source	ACADIA 2105: Computational Ecologies: Design in the Anthropocene [Proceedings of the 35th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-53726-8] Cincinnati 19-25 October, 2015), pp. 81-94
summary	This paper outlines a material based research that proposes a time-based architecture that extends Frei Otto’s research of sand formations using sand’s natural angle of repose. The tectonic system focuses on developing compressive structures of sand for hot climate desert areas through a zero-waste formative process whose architecture reorganizes materials naturally available on the site. Formations are hardened as a surface through the phase changing properties of a saline solution which crystallizes when cooled, bonding with the sand. The proportion of insulation material defines the building life span redistributes the materials back into its environment at the end of its cycle. The materiality and spatial qualities of the project are based on the conical and constant angle surfaces generated through the gravitational process of sand formation. Between the digital opportunities of sand formation and its physical possibilities, this paper outlines the analogue-digital methods of sand computation through a comprehensive study in four main sections; material system, material computation, design system and robotic fabrication.

title	Bodies in Formation: The material evolution of flexible formworks

summary	Borne from the complex negotiation between liquid mass and tensile constraint, flexible formwork castings are resonant with material energy. Hard as stone, yet visually supple and fluid, the pre-cast architectural assemblies produced using flexible formwork techniques suggest integrative design strategies that acknowledge the intricate associations between form, fabrication, and material behavior. This tripartite synthesis between geometry, making, and performance has emerged as one of the central themes of contemporary architecture and engineering. Borrowing ideas of morphology from biology and physics, 20th century architectural innovators such as Antoni Gaudi and Frei Otto built a legacy of material practice that incorporated methods of making with material and geometric logics. The emergent effects (and affects) produced through these highly integrative practices serve as the basis of much of the research and design at Matsys. Building on the flexible formwork research of Miguel Fisac in the 1970s, the P_Wall series by Matsys explores the use of digital tools in the generation and fabrication of these bodies in formation.

title	Parametric Urban Models Based on Frei Otto’s Generative Form-Finding Processes

summary	Presently there is a progressive tendency to incorporate parametric design strategies in urban planning and design. Although the computational technologies that allow it are recent, fundamental theories and thinking processes behind it can be traced back to the work conducted at the Institute for Lightweight Structures (IL) in Stuttgart, between the 1960’s and 1980’s. This paper describes an experimental urban research work based on Frei Otto and Eda Schaur's thoughts on unplanned settlements, and on the form-finding experiences carried out at IL. By exploring the digital development of parametric and algorithmic interactive models, two urban design proposals were developed for a site in Porto city. Out of this experience, this paper suggests that today the act of design can benefit from a deeper understanding of the natural processes of occupation and connection.

summary	Part of our research and teaching agenda at the School of Architecture of the Technical University of Crete focuses on algorithmic design with parametric models, its methodological characteristics and the study of applied and theoretical work that defined this architectural design thinking. Our work challenges architectural design processes, through the systematic study of parametric models. This paper presents three projects from the undergraduate elective course "Special Topics in Architectural Design", which took place during the spring semester of 2017, that investigated parametric models for a given architectural problem, inspired, to some extent, by precedents in 20th century architecture where students traced algorithmic design thinking. Although students understood well the concept and function of parametric models and in many cases applied them successfully for their design objectives, several of them did not fully assimilate some critical aspects of computation. This allowed us to determine areas of improvement and points of complete reevaluation in our educational strategy approach.

summary	Current dominance of functionalist and performance related approaches to computational design and methods in architecture are investigated under the precondition of Max Bense's theory of aesthetic potential. Establishing Bense's taxonomy of aesthetic potential and applying it to selected computational methods the level of aesthetic potential within the different computational approaches is investigated. Frei Otto's soap bubble experiments serve as a reference to illustrate different levels of aesthetic potential. Bense's aesthetic potential, which lies not in the eye of the beholder but is immanent to the object itself as a property of the object, suggests that computational design systems synthesising objects based on rules or embedded constraints appear to either have little aesthetic potential or receive their aesthetic potential form the outside of the computational system, namely the interaction with the user. Evolutionary design systems appear to create objects or processes with a certain aesthetic potential within Bense's theoretical framework.

summary	The paper presents a research on real-time shape exploration employing analogue and digital form-finding and concludes with a proposal for a teaching methodology that led to an intensive student workshop which took place at Graz University of Technology during 2014. The aim was to experiment with analogue and digital tools in parallel, counter-informing the design process. The experiments involved physical form-finding following the tradition of Frei Otto at the Institute of Lightweight Structures in Stuttgart as well as computational form-finding employing mainly dynamic relaxation techniques of spring-particle systems. The combination of techniques and methodologies eventually led to a feedback loop across different media that explored both qualitative and quantitative characteristics of the projects at hand. By establishing feedback between digital media and physical prototypes, the creative process is immediately informed by the material characteristics and properties which in turn give rise to a real-time exploration of form.Simulations of physical forces for architectural form generation are increasingly gaining ground in architectural education as there is a broad selection of computational tools readily available that allow quick experiments to be conducted.

summary	We present a parametrical approach to movable polyhedral models. Based on polyhedral geometry the whole structure consisting of an interconnected series of prisms (with dual spherical joints) can move 3-dimensionally. The principles of polyhedral geometry allow constraint movements of the prisms with a certain degree of freedom. We use these geometrical principles to open and close façades for ventilation or structures for shading control superimposed on building envelopes. The different groups of regular polyhedra in the Euclidean 3-space and their specific topological types will be discussed in order to choose the appropriate model and showe geometrical theory of movable polyhedral models can be successfully applied to performative architecture.

summary	As one of the oldest schools of architecture in Germany, Dresden has a long and continuous tradition in the field of architectural aesthetics and building composition. Architects such as Fritz Schumacher initiated research and teaching in the field in the 1920s, and this was revitalised during the 1950s by Otto Schubert who laid the foundations for a scientific description of the correlation between optics and architectural design, and also worked towards a comprehensive theory of architectural composition. As a result of the architectural ideology of the East German regime, such studies were consigned to near oblivion and the main concern became interior decoration. With the appointment of Professor Ralf Weber, the institute was reestablished in 1994 under its original name, the Institute of Spatial Design (Raumgestaltung). Its new research agenda originated from Weber’s book “On the Aesthetics of Architectural Form - A Psychological Approach to the Structure and the Order of Perceived Architectural Space” (Ashgate 1994). In order to verify some of the hypotheses advanced in the book empirically, members of the institute have been carrying out a number of studies in the areas of oculomotor research and the perceptual foundations of design, and have been addressing issues that would help formulate principles of good architectural form and space applicable to the everyday practice of architectural design. Currently, the Institute of Spatial Design focuses on the further development of the psychological bases of experiencing architecture, as well as on theories of aesthetics and their application in practice. Specifically, attention is paid, on the one hand, to the perception and experience of architecture, i.e. aesthetics, and on the other, to the assemblage of various parts into an overall whole in a building, city or landscape – in other words, architectural composition. These two aspects are naturally inextricably intertwined: the one concerns the reception of architecture, the other, its production. Under these headings, various other areas of interest, such as architectural tectonics, systems of order and proportions, or the issue of scale in architecture, are tackled through dissertations, research projects and seminars. The institute has been cooperating on several studies with the Cognitive & Biological Psychology Unit at the University of Leipzig and the intention is eventually to establish an interdisciplinary research unit for architectural aesthetics.

summary	The paper presents an algorithmic modeling tool for segmented timber shell structures made of glued wave-edge CLT plates. The goal is to provide a larger bonding area and thereby higher adhesive strength between plates, especially where a higher tension-resistant capacity is required. In addition to a number of contemporary research for exploring stereotomic modules, the inspiration is taken from the long history of the traditional glued finger joints in carpentry where they are used for providing higher interlocking capacity and adhesive strength. The structural performance of regular and glued finger joints is directly proportional to the bonding area between adjoining elements where they are interlocked and glued. Hence, expanding the shared faces would intrinsically magnify the structural performance of the glued finger joints. The paper presents the modeling method of a material-efficient, grain-informed, and structurally-optimized wedge edge joint system for the multi-shaped shell structures where the wave pattern is chosen for generating smoother fabrication toolpaths compared to any sharp-cornered pattern. The algorithm developed by the authors can efficiently maximize the glue bond by optimizing the wave-edge properties dynamically with respect to the geometric design, material system, and structural analysis within a feedback loop. The wave-edge properties directly affect the material waste and fabrication time and cost; therefore, the production parameters could be directly considered and controlled within the design process. The algorithm is able to produce the structural data model for the direct RFEM structural analysis, and fabrication data for automated production of multitude elements. The paper argues the application possibilities and limitations of the joint system for multi-shaped timber plate shells made of a multitude of geometrically-differentiated timber plates.

summary	Tension active systems are compelling architectural structures having an intimate connection between structural performance and the arrangement of material. The direct flow of structural forces through the material makes these systems attractive and unique from an aesthetic point of view, but they are a challenge to develop from a design and an engineering perspective. Traditional methods for solving such structural systems rely on both analog modeling techniques and the use of highly advanced engineering software. The complexity and laborious nature of both processes presents a challenge for iterating through design variations. To experiment with the spacemaking capabilities of tension active systems, it is necessary to design methods that can actively couple the digital simulation with the analog methods for building the physical structure. What we propose is a designer-authored process that digitally simulates the behaviors of tension active systems using simple geometric components related to material and structural performance, activated and varied through elemental techniques of scripting. The logics for manufacturing and assembly are to be embedded in the digital generation of form. The intention is to transform what is a highly engineered system into an architectural system where investigation is as much about the determination of space and environment as it is about the arrangement of structure and material.

summary	As computational design processes have moved from representation to simulation, the focus has shifted towards advanced integration of performance as a form defining measure. Performance, though, is often assessed purely on the level of geometry and stratified between hierarchically independent layers. When looking at tension-active membrane systems, performance is integrated across multiple levels and with only the membrane material itself, defining the structural, spatial and atmospheric qualities. The research described in this paper investigates the integrative nature of this type of lightweight structure and proposes methodologies for generating highly articulated and differentiated systems. As material is a critical component, the research focuses on a system-based approach which places priority on the inclusion of material research and parameterization into a behavior-based computational process.
