title	Dynamic Relaxation of Tensegrity Structures
doi	https://doi.org/10.52842/conf.caadria.2009.553
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 553-562
summary	The structural hierarchy inherent to tensegrities enables a building skin that performs on multiple levels simultaneously. While having one function in the global building mechanics, its individual components can work as self-contained systems balancing tensile and compressive forces locally within them. The behavior of elements under load is linear and thus describable analytically. When these are aggregated in a tensegrity however, the performance of the assembly as a whole is non-linear. In order to investigate further these relationships a method of dynamic relaxation will be developed. This tool allows for simulation and load analysis of a complex tensegrous network, based on the relationships between force, stiffness and dimension formulated by Young and the computational means provided by a parametric/associative modeling environment. This research investigates the possible formfinding through computational means of a double-layer tensegrity grid.

title	Parametric Constructionist Kits: Physical Design and Delivery System for Rapid Prototyping Devices
source	International Journal of Architectural Computing vol. 7 - no. 4, 623-642
summary	In this paper we illustrate a design methodology based on constructionist learning principles with CAD modeling and rapid prototyping. The belief is that a constructionist approach to design development extends design possibilities beyond the visual aspects of rendering and animation to building construction by way of component-based parametric modeling. This is demonstrated by way of construction kits as a proposed system of physical design production, individually and in groups. Results of the system are data sets for model manufacturing, hand assembly and design feedback. The impact of this work is to teach physical modeling as a system of production that will allow a designer hands-on learning of building structure, material mechanics and building component behavior. Also design success is newly defined as a relationship between the visual and physical evaluation; not just the visual. The paper ends with examples of complex design models generated from elements in the construction kit and a physical design grammar used to guide element assembly. Although the examples in this paper satisfy model making for building structures we believe this system can be useful for anyone who needs to construct physical artifacts beyond traditional scales found in rapid prototyping.

title	VirtusCADE, um Sistema para o Design Virtual de Produtos [VirtusCADE, A system for virtual design of products]
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The knowledge of latest technology that allows the development of competitive products in reduced times is crucial to guarantee a sustainable growth of the national industry. This work presents the development of a computational system for the Virtual Design of products, the VirtusCADE, which is a CAD/CAE interactive software (Computer Aided Design/Computer Aided Engineering). The VirtusCADE includes 3D geometric modeling of surfaces and solids and mesh generation. The system uses the parametric modeling of surfaces, including algorithms for determination of intersection between surfaces and for triangular mesh generation in trimmed parametric surfaces. The graphical interface is interactive and allows the direct real time manipulation of objects (lines, surfaces and solids) in 3D using the OpenGL technology. The system prioritizes the usability, implementing several graphic tools that facilitate the manipulation in 3D. The VirtusCADE contemplates the structural simulation through the Finite Element Method. The code architecture is based on oriented object programming, which allows great scaling capability for the implementation of new tools. This project has great applicability in numerical simulation of physical phenomena, such structural analysis of buildings, vehicles parts, with impact in the industries of civil construction, metal-mechanics, aerospatial, naval and automotive.

title	From texture to volume: an investigation in quasi-crystalline systems
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The relation between texture, pattern and massing is a fundamental question in architecture. Classical architecture, as Leon Battista Alberti states in “De re aedificatoria” (Book VI, Chapter 2), is developed through massing and structure first; texture is added afterwards to give the bold massing and structure beauty. Only the ornamentation adds pulcritudo to the raw structure and massing. Rather than starting with a volume and applying texture afterwards, the Digital Girih project started with textural operations that informed the overall volume later. The stereometric, top-down methodology is questioned through the bottom-up methodology of the Girih project. Girih lines of traditional Islamic patterns were used as a starting point. The aspect of 3-dimensionality was developed analogue as well as digital, using the deformability of different materials at various scales and digital construction techniques as parameters. The flexibility within the Girih rules allowed the system to adapt to different tasks and situations and to react to different conditions between 2- and 3- dimensionality. The project in that way explored a bottom-up process of form generation. This paper will describe the process of the project and explain the necessity of digital tools, such as Grasshopper and Rhino, and fabrication tools, such as laser cutter and CNC fabrication technology, that were essential for this process.

source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	This article reviews the work and the artistic and architectural context of the artist Gordon Matta-Clark. It checks the context as well as the urban and social conditions of his interventions, to place these works in contemporary culture. In particular this paper analyzes “Splitting”, Matta-Clark´s work that synthesizes his critical attitude to the Modern condition; using computational techniques of geometric modeling, visualization, graphics, digital manufacturing and structural analysis to explore and determine the formal rules and materials used by the artist to develop actions with significant spatial and social connotations.

title	Generative Craft
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	Popular discourses and representations of automation in design practice have often committed to an ontology of design and creativity where both materials, media and tools are rendered passive actors in design processes. The ways in which these narratives are articulated have consequences for how the materiality of media and of construction elements is construed in both design discourses and environments. Providing a brief critical history of the mutual construction of design technologies and notions of creativity and design is a concern of this paper, which concludes with a critical re-writing of disembodied conceptions of automation in design.

summary	A system for using organic polymers as electrochromic components for a building’s facade is proposed, and early prototypes are presented. The potentialities of such system, Croma, are considered in two aspects: a) as interactive facades that change opacity in reaction to touch –hence “drawing with transparency”- and b) as elements to automate energy-smart behaviors of a building. Some implications are discussed.

title	Digital Craft Meets the Ancient Art of Ceramics: Would the Bauhaus Approve?
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The Bauhaus was founded upon the controversial premise that emergent mechanical processes offered new and creative ways to explore materials. Today, we encounter equally tendentious scenarios where the designer often appears one step further removed—automated CNC machines are driven by computational machines. Like the early activities of the Bauhaus some view digital pursuits with suspicion; however, digital design/fabrication is the “Nächster Bauhaus Bewegun” offering opportunities for design innovation equal in significance to that of the Bauhaus. This paper partially examines the theoretical implications of digital design/fabrication, then presents a collaboration between an architect and artist re-examining the architectural cladding possibilities using digital tools to shape one of mankind’s most venerable materials—ceramics.

summary	Our digital carving experiments reveal ways to invite discovery into the design process. Working with sketched lines, handcrafted finishing, geometric overlay, and tool path coding can lead a designer to unexpected results. Concentrating on forming processes moving through material over time encourages open-ended play. Iteratively examining how computer operations generate carved results provides a craftsman’s understanding of tools and materials.

source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 472- 486
summary	One of the research ways carried out in the ARIAM-LAREA laboratory aims at giving to architects computing tools for early evaluation of structures. A particular approach uses dimensional analysis and similitude properties in order to define parameter variation laws. Such laws are illustrated by analytical cases using the theory of strength of materials. For complex structures, a heuristic is proposed to give indications of parameter variation influence on mechanical behavior. Some applications are presented for early determination of structural size and limit values, using computations by finite element method.

summary	There have been, very broadly, three eras in the understanding of matter in design. The first, associated with an Aristotelian view of matter as inert and as a receptacle of form, has dominated many of the formalisms in Architectural Design from the Renaissance through to Modernism. The second, sometimes described as “new materialism” (Menges 2012), considers matter as active through design processes which work with materials’ inherent tendencies and capacities. This has led to now-familiar design methods, including Material Based Design Computation (Oxman 2009), and many experiments with active materials such as bilayer metals and hygromorphs. These materials can be programmed to respond to their environments and often take inspiration from biology. I want to suggest that we are entering a new era of understanding matter, which I refer to as the “agential era.”

title	Preserving memories with digital media: a methodology for the reconstruction of Castelnuovo Village
doi	https://doi.org/10.52842/conf.caadria.2010.083
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 83-92
summary	The historical centre of the village of Castelnuovo (located in Abruzzo, a region in central of Italy) was seriously damaged by the earthquake of the 6th of April 2009. Following the survey by the Civil Protection, all dwellings have been classified as unsuitable for habitation. The village should be either abandoned or totally rebuilt. But which is its value? Is there something worth of being preserved? If observed from a biodiversity point of view, or more precisely from a “cultural biodiversity” point of view, the historical centre possess interesting materials and immaterial characteristics. These qualities constitute real guidelines for a possible recovery project. Since there is not any possibility to make a survey of the inner village because of its destruction by the earthquake, in this research we have decided to use information technology, in order to rebuilt it and study it in a three-dimensional environment. In this paper we describe the theoretical basis, the method of elaboration and the instruments we have used to locate and evaluate the memories that should be preserved in a new project. Starting with a traditional documentation, such as photographs and drawings, we have used a variety of software (graphics editing program, CAD, 3D modeler, videogame 3D-engine), because of the several hypothesis considered.

summary	The materialization of architectural forms uses new processes aided by digital manufacturing techniques (FD). Five FD techniques stand out: sectioning (serial planes), tessellation, folding, contouring, and forming. This article's objective is to characterize the state of the art of these techniques, from 2009 to 2020 in national and international research bases. The Systematic Literature Review is used from three stages and nine protocol phases. The results indicate the techniques, methods, computer simulations, and applicability in more recurrent materials.

summary	The deconstruction (DeCon) and repurposing (ReCon) of existing structures and materials are worthwhile and relevant endeavors given the potential for such procedures to be more economically and environmentally sustainable than conventional construction methods. Conventional construction methods often utilize virgin materials for the production of architecture, requiring extensive energy to harvest, process, and manufacture the materials for use. Today, we must face the fact that we exist in a carbon-sensitive economy, and demand design approaches that reduce architecture’s impact on the environment. Our goal was to develop a CADCAM ReCon design methodology that would have the potential to mitigate carbon consumption. To explore this goal, students engaged a design research project that looked for novel and innovative approaches to the DeCon and ReCon of an existing barn. The student researchers created parametric models and surface designs derived from the existing materials. The digitally fabricated tectonic design constructions resulted in economical, novel, and material-efficient design methodologies for DeCon and ReCon.

title	Appropriating Donald Schön
doi	https://doi.org/10.52842/conf.caadria.2009.483
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 483-492
summary	Donald Schön embraces a constructivist approach to learning and research., characterising designing as a reflective conversation between designer and the materials of a design situation. Accordingly, Schön’s views on digital design support are based on his valuing of indeterminacy, surprise and ambiguity as opportunities to develop new understanding and insight. His criticism of technical rationality is directed towards the privileging of formal and codified knowledge over embodied and tacit forms of knowing. While Schön’s work is increasingly acknowledged in recent CAAD research, respective publications typically remain within the technical rationality perspective. Based on several characteristic examples, this paper examines how Schön’s ideas are absorbed into a perspective incongruous to his own, concluding with a discussion of potential new research approaches that sustain Schön’s values.

title	Virtual Organism: Generative Tool Based on Multi-Agent System
doi	https://doi.org/10.52842/conf.caadria.2009.625
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 625-634
summary	A multi-agent system (MAS) is efficient as it can emulate a variety of organisms in natural science due to the interactions between agents, which make artificial systems responsive and adaptive. In “Bamboo Workshop” involved flexible structures, MAS was employed to create virtual organism in computational environment towards an innovative process in installation design. A generative tool with friendly user interface was developed for both observation and intervention besides debugging. At the same time investigations were carried on the complex behaviours of the system through graphic statistics. Integrated with the generative tool, a construction system made up of bamboo materials was set up to build a series of mobile and flexible installations. This experiment suggests that the virtual organism has the potential for being a part of the design intelligence, beyond a mere digital tool.

title	On The Design Communication of Cultural Image
doi	https://doi.org/10.52842/conf.caadria.2009.401
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 401-410
summary	In this era, people are no longer satisfied with standardized products. Designers need to implement unique product semantics to attract customers to buy the products. According to this reason, designers are developing a new design approach that puts cultural elements into their products so that they can make people reappreciate their own culture and history. The Olympics is a global event which involves various sport competitions. Before the Beijing Olympic Games, many host nations used to promote their culture through selling a variety of merchandise. It is the first time for the Olympic Games to take place in China which means that it is obviously the right timing to see cultural symbols of China in the merchandises created by the Chinese design team. These designs had introduced Chinese imageries to the whole world. As generally known, traditional culture of Taiwan actually took root from China. Taiwan owns the same ancient history and materials like China. This study explores the cultural identity and analyses the cultural design elements of China. The 2008 Beijing Olympic Games is taken as case study in this research, because it helps people think how to create new value from their own culture. Furthermore, this paper proposes some suggestions on how to create design which represents the image of Taiwan.

summary	Reinforced concrete has been one of the essential materials for modern architecture for the last hundred years. Its use is entirely global, having been adopted by all cultures and styles since its invention in the late 19th century. Although its value is excellent due to its low cost, durability and adaptability, its environmental impact is significant, being, in fact, one of the most polluting industries in the world (Babor et al. 2009). This experimental project will research a more sustainable use of concrete, exploring a new form of reusable concrete formwork that will ideally reduce the CO2 footprint by removing wood waste in the casting process and replacing it with adaptable metal components. The modular part-based system for the concrete casting also attempts to simplify one of the current complexities for concrete construction, the Skilled-Labour shortage. (Yusoff et al. 2021). To mitigate this problem, the project also proposes using an Augmented Assembly logic for the casting parts to guide the ensemble and dismantle the formwork through an optimised algorithmic logic. The use of Augmented Reality as a replacement for traditional paper instructions will facilitate access to more workers to this construction art and potentially improve access to optimised use of concrete in developing communities with restricted building technological resources.

summary	The design and fabrication of an exhibition display project was taken as an opportunity to explore parametric design with a group of students in Chile. This article presents the experience of a design studio workshop exercise by addressing the introduction of parametric design principles and the development of a built academic project through a team based design and fabrication process. The strategy followed by the team was to utilize parametric models as a mean to materialize driving variables of the project into unexpected geometries to be deployed in different public spaces in Santiago. Context, time scale and available technology resulted in a non-obvious combination of advanced digital design and fabrication techniques and low-cost mass-produced materials.

source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The main objective of this research is to determine through the use of a CAD-BIM system, the emission of CO2 in the pre-operational phase of construction. Based on a case study in quantitative analysis of materials and the BIM system, it was possible to quantify the amount of CO2 emitted during the pre-operational life cycle of a building. By using this feature you can provide, before the begining of construction, the total CO2 that will released to the environment, and other analysis.
