title	Approximation Concepts for Optimum Structural Design
source	25 p. Pittsburgh, PA: Design Research Center, CMU, December, 1982. DRC-12-12-82. includes bibliography
summary	When elastic behavior is assumed, the optimum structural design problem is stated in an implicit nonlinear programming form. Approximate behavior models are introduced to obtain explicit constraint functions, essential in many practical design problems. For the displacement analysis formulation, some possible explicit approximations of the nodal displacements in terms of the design variables are reviewed. It is shown that any approximation of the displacements will lead to a solution which does not necessarily satisfy equilibrium. Methods for solving the approximate problem are discussed. Using the force analysis formulation, it is shown that explicit approximations of the redundant forces will lead to solutions which do not necessarily satisfy compatibility. Some simplified models of the explicit problem are presented and solution methods are discussed

title	Optimal Design of Continuous Prestressed Concrete Structures
source	25 p. : il. tables Pittsburgh, PA: Design Research Center, CMU, December, 1982. DRC-12-11-82. includes bibliography: p. 20-21
summary	Optimal design of continuous prestressed systems is stated in a nonlinear programming form. The design variables are the concrete dimensions, tendon coordinates, and prestressing force. The constraints are related to various behavior and design requirements and the objective function represents the overall cost. Some simplified models, intended to improve the solution efficiency, are presented. These include: explicit formulations of the general problem and the problem of minimizing the concrete dimensions; linear programming formulation of the tendon configuration and prestressing force optimization; and direct determination of the prestressing force for given concrete dimensions and tendon coordinates. Some examples illustrate the various problem formulations and solution methodology

title	Double-Curved Form Approximation with Identical Discrete Panel Geometries
source	P. Janssen, P. Loh, A. Raonic, M. A. Schnabel (eds.), Protocols, Flows, and Glitches - Proceedings of the 22nd CAADRIA Conference, Xi'an Jiaotong-Liverpool University, Suzhou, China, 5-8 April 2017, pp. 457-466

summary	To reduce the costs of manufacturing multiple moulds for double-curved facade construction, this research suggests a method of approximating the desired envelope with identically formed panel geometries. The panels can then be fabricated by only using two double-curved moulds. In a second step, individual segments are cut out of the identical base geometries. The method has been successfully tested with the construction of a prototype. The result is an intricately textured free-form geometry. The installation was built at a reasonable cost compared to other ways of fabricating double-curved geometry. The strength of the panels was utilised as the sole structural system of the prototype.

summary	Digital output from computer modeling represents a significant new method for visualization and fabrication of architecture. The ability to move directly from three-dimensional modeling to real three-dimensional output challenges the need for traditional means of representation such as plan, section, etc. Moreover, the necessity for conversion of architectural intentions into a code (construction documents, shop drawings, etc.) to be translated by the contractor will also be tested with these new potentials in fabrication. This subjugation of traditional forms of representation and fabrication has serious implications for architectural design process and production. The intention of this paper is to scrutinize underlying issues inherent in a design process of developing architectural solutions using the computer both as a tool for threedimensional visualization as well as for guiding three-dimensional fabrication. Precedent of historic expressive architectural form (seen through the lens of fabrication) will be presented to lay the foundation for the examination of new fabrication techniques and structural concerns for computer generated expressive forms. A series of rapid prototype studies from a digital architecture seminar will also be analyzed to outline the need for developing visualization/fabrication process ideas and research into methods for making digital architecture.

title	Digital Design through Production Pedagogy: Cases Involving Student/Industry Collaboration
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	Innovation through digital design in contemporary practice has led to completely new ways of designing and making architecture. To prepare for these innovative opportunities, students are turning to alternative skill sets than those traditionally gained in an architectural curriculum. This paper argues that we must reconstruct our architectural curricula in order to better prepare students for a shifting professional landscape. While current material-based production realities of translating digital design into built form have much in common with modernist traditions, exercises, sequences, and collaborative opportunities in schools should pass through a relevant lens examining the true potential of working with the information age.

summary	Parameters within a highly collaborative design-through-production process range from a very broad set of influences. To address the conundrum of selecting operational logics, we begin searching for form genesis with an examination and reproduction of the past in order to both restore and formulate a contemporary response to an existing ceiling within an iconic space, designed in 1964 by Alexander Girard in the atmosphere of significant architectural design influences radiating from Columbus, Indiana. Methods learned from analysis of original production are used, and synthesized as guiding principles in the design-through-production process of contemporary work.

summary	My work is research focused. Broadly speaking, I’m interested in the “How” of creative production, as opposed to the “What”. I ask “How is this?” not “What is this?” I am interested in “How” designs and things are made or become, in the processes or paths to form, whether abstract or material. As a process carried out over time, computation offers a unique means for understanding and describing the “How” of design and making. I explore this potential with shape grammars and, most recently, with making grammars. The unique visual and spatial nature of the rules and computations of these grammars is aimed at unveiling the “How” in design.

title	Pixel-Based Geometric Decoding of Mondrian Compositions
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. 103–114
summary	This study explores the use of a computational method for decoding and encoding an art composition in the digital environment. Geometric decoding includes subdivision through color and shape. Five artworks of Mondrian, which contain simple but intense geometric data and have a unique composition style, are discussed in this context. Matrix-based expression of composition in terms of color and form with a code-based analysis allowed to definition of a control mechanism for existing geometric data. The aim of this decoding process, which follows segmentation and fragmentation methods, is to capture the common composition approach and particular comparison approach. Visual encoding, as the reverse of the decoding process, is the interpretation of the data obtained as a result of the analysis by assigning a color map. By this meanings, the matrixes and visual outputs enable the artworks to be compared according to the main composition style, or the similarities between them.

summary	Kukje Art Center, Seoul’s new gallery designed by SO-IL, features a totally bespoke chainmail mesh system (submission note: the authors are not affiliated with SO-IL). A single sheet of complex-curved, tensioned mesh, made up of interlocking 40mm diameter stainless steel rings, wraps the building. This paper discusses the stages of a feedback loop process employed by the authors to refine a digital model of the mesh. The mesh’s perimeter attachment system does not prescribe ring locations, allowing the mesh to form find for itself during installation. As a result, the digital model must capture the behavioral tendencies of the mesh as it negotiates the building’s geometry. Paramount in meeting this challenge was the use of physical mockups. At each stage of the feedback loop process, the working digital model was used to develop a physical mockup of increased scale and complexity, and this mockup was used to refine the digital model. Ultimately, the model output of a mesh relaxation algorithm was used as the basis for engineering simulations and predictions of the mesh vertical ringcount needed at specific locations around the building. Mesh vertical ringcount predictions are validated relative to a 1:1 mockup and the installed Kukje Art Center mesh.

title	Exploring Building Typologies and their Socioeconomic Contexts: Compositional Insights from Large-Scale-Text-to-Image Models
source	ACADIA 2023: Habits of the Anthropocene: Scarcity and Abundance in a Post-Material Economy [Volume 2: Proceedings of the 43rd Annual Conference for the Association for Computer Aided Design in Architecture (ACADIA) ISBN 979-8-9860805-9-8]. Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 508-517.
summary	This study utilizes large-scale-text-to-image (LLI) models to investigate possibilities to describe building types data-centric. With the introduction of ""data-centric typologies"" we hope to challenge traditional architectural classification systems, while reviving type as an architectural strategy to link socio-economic contexts to the physical form of a place. By examining artificial intelligence (AI)-generated images of various city buildings, the research explores compositional characteristics, realism, and model limitations. We generated and segmented a synthetic dataset of 15,000 images into individual building segments, conducting a statistical analysis of compositional features across 500 cities. Despite dataset biases and limitations, our results indicate that synthetic databases provide a deeper analytical basis than traditional methods. The generated dataset alone paints forensic landscapes of locales that are not typically showcased. Particularly from a pedagogical perspective, data-centric investigations can serve as a valuable tool for illustrating the diversity of cities and living modes. The findings show that socio-economic attributes, like quality of life, are more closely tied to neighborhoods or projects than entire cities. Consequently, architectural typologies are most effective at a human-ori- ented scale, interfacing city with architecture.

summary	Visual impression of city form is related to its morphology of buildings and its spatial constellations. They present themselves in different lighting conditions. According to the daytime and seasonal impression, building elements run across in a different but constantly visible way. When night-time comes along the whole system is busy, indifferent and out of control. It is unsteadily illuminated rather in accordance to its purpose than to the structure of building or space.

summary	Increasingly, the ubiquity of satellite imagery has made the data analysis and machine learning of large geographical datasets one of the building blocks of visuospatial intelligence. It is the key to discover current (and predict future) cultural, social, financial and political realities. How can we, as designers and researchers, empower citizens to understand and participate in the design of our cities amid this technological shift? As an initial step towards this broader ambition, a series of creative web applications, in the form of visual search engines, has been developed and implemented to data mine large datasets. Using open sourced deep learning and computer vision libraries, these applications facilitate the searching, detecting and curating of urban objects. In turn, the paper proposes and formulates a framework to design truly citizen-centric creative visual search engines -- a contribution to citizen science and citizen journalism in spatial terms.

summary	Inside the current esthetics arisen from the digital art, I recognize PXEL ART as a vanguard. Not only because of its craft and methodology (the form to work it, beyond its content) but also because of its sense, which is to claim the most minimum unit from a digital perception. Even though the term 'vanguard' seems to have disappeared in our times, my intention is to differentiate ~Pixelism~ from a simple esthetic position or modern wave.

source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 203-218
summary	This paper describes a prototype system that evaluates an architectural design using the designer's theories about how to manifest experiential qualities in physical form. The system uses Al methods in conjunction with geometric and non-geometric knowledge to represent experiential qualities, e.g. privacy, in terms of concrete details of a design, e.g. wall dimensions and locations. This paper describes the organization and implementation of the system, and reports the results of an experiment in which the system was used to evaluate Frank Lloyd Wright Prairie houses.

doi	https://doi.org/10.52842/conf.acadia.2006.095
summary	The paper examines the newfound capacity to digitally design and manufacture highly crafted material and surface effects. It traces an emerging trajectory in contemporary architecture aimed at the decorative effects of digitally crafted surface patterns and textures, as a potential return to ornamentation in architecture. It surveys practices whose approach to form and pattern varies from the “ornamented minimalism” of Herzog and de Meuron to the “expressive exuberance” of Greg Lynn. The paper also describes the different digital modes of material production aimed at particular surface effects, as in series of panels with repetitive, yet unique decorative relief or cutout patterns, striated surface configurations, etc.

keywords	This paper presents an ongoing work towards the development of an integrated robotically-driven workflow that can be used for the design, development and subsequent fabrication of small-to large-scale elastic tensile mesh structures. This approach involves digital form-finding and optimization, driven by robotic manufacturing principles and it aims to overcome the limitations of currently available tools, to work either in the design or the fabrication phase of the process. At the same time, it involves the fabrication of systems in several scales followed by respective analyses of results according to the specific type and diameter of the material used. Specifically, form-finding and optimization are responsible for controlling the pretension of the elastic threads, aiming to determine the final tensile mesh and to generate the additive robotic tool-path. In parallel, the type and diameter of the material involved, define the necessary changes of the end-effector tool, which is responsible to implement the process. Despite that design results can be in any scale, for study purposes an experimentation into a small-scale is conducted, to evaluate the suggested automated construction process in general and the end-effector mechanism in particular.

title	Architecture and Hyperdocument: Data Shaping Space
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 462-465
summary	The computer interface can't convey the hole experience of walking through a city or a building. Nevertheless, the complexity of all the aspects involved in those threedimensional spaces can be better understood through the non-linearity of the hyperdocument. Each dweller of a city and a building has many layers of relationship with both. The sequence and the extent each observer explores the space is unique. It’s not totally apprehended in a first visit. As the observer knows better that space, his experience changes. A similar situation takes place in a multimedia application. Hence, it's possible to build an analogy between the architectonic or urban structure and a hyperdocument navigation structure. We can also state that the computer is critical to create paths of architectural information through space and time. The 3D model of a city is a powerful basis to structure the hyperdocument navigation. The city can be viewed in separate parts or layers of information. One investigates the city through different aspects of its configuration and explores it in different scales and levels of detail. The images generated from this 3D model can be combined with video, photo, sound and text, organizing the information which gives form to the city. The navigation through this information, addresses the citty by its economy, housing, religion, politics, leisure, projects, symbolic buildings, and other aspects. This paper will discuss these issues through the experiments of the research done at the School of Architecture and Urbanism of the Universidade Federal do Rio de Janeiro. The research group at the "Laboratory of Urban Analysis and Digital Representation" in PROURB (Graduate Program of Urbanism) analyses the city and its buildings using CD-ROMs and websites.

summary	Parallel to the early development and recent widespread usage of composite materials in building and manufacturing, the concept of functionally graded materials (FGM) was initiated and developed as far back as the 1980s. In contrast to the composite paradigm, where layers of materials are glued and 'cooked' together under high pressure and temperature to form laminated parts, FGM are singular materials that vary their consistency gradually over their volume. In direct link to their increasing use in fields adjacent to architecture, the scope of the paper is to explore a possible design route for designing with FGM. Of a limited number of available CAD software where material properties can be graded, the intent of the design for a materially graded windbreak module is to utilize particle systems as a technique for simulating fields of interacting, information-loaded material point sets that can be fused together in a gradient manner.
