title Road hierarchy and speed limits in Brasília/Brazil

summary This paper aims at exploring the theory of the Social Logic of Space or Space Syntax as a strategy to define parameters of road hierarchy and, if this use is found possible, to establish maximum speeds allowed in the transportation system of Brasília, the capital city of Brazil. Space Syntax – a theory developed by Hillier and Hanson (1984) – incorporates the space topological relationships, considering the city shape and its influence in the distribution of movements within the space. The theory’s axiality method – used in this study – analyses the accessibility to the street network relationships, by means of the system’s integration, one of its explicative variables in terms of copresence, or potential co-existence between the through-passing movements of people and vehicles (Hillier, 1996). One of the most used concepts of Space Syntax in the integration, which represents the potential flow generation in the road axes and is the focus of this paper. It is believed there is a strong correlation between urban space-form configuration and the way flows and movements are distributed in the city, considering nodes articulations and the topological location of segments and streets in the grid (Holanda, 2002; Medeiros, 2006). For urban transportation studies, traffic-related problems are often investigated and simulated by assignment models – well-established in traffic studies. Space Syntax, on the other hand, is a tool with few applications in transport (Barros, 2006; Barros et al, 2007), an area where configurational models are considered to present inconsistencies when used in transportation (cf. Cybis et al, 1996). Although this is true in some cases, it should not be generalized. Therefore, in order to simulate and evaluate Space Syntax for the traffic approach, the city of Brasília was used as a case study. The reason for the choice was the fact the capital of Brazil is a masterpiece of modern urban design and presents a unique urban layout based on an axial grid system considering several express and arterial long roads, each one with 3 to 6 lanes,

title TAP – The Architectural Playground - C++ framework for scalable distributed collaborative architectural virtual environments
source Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 422-426

summary Architecture is built information (Schmitt, 1999). Architects have the task of restructuring and translating information into buildable designs. The beginning of the design process where the briefing is transformed into an idea is a crucial phase in the design process. It is where the architect makes decisions which influence the rest of the design development process (Vries et al., 1998). It is at this stage where most information is unstructured but has to be integrated into a broad context. This is where TAP is positioned – to support the architect in finding solutions through the creation of spatially structured information sets without impairing thereby the creative development. We want to enrich the inspiration of an architect with a new kind of information design. A further aspect is workflow in a distributed process where the architect’s work becomes one aspect of a decentralised working patterns. The software supports collaborative work with models, sketches and text messages within an uniform surface. The representations of the various media are connected and combined with each other and the user is free to combine them according to his or her needs.

title A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

title Conformance Checking by Capturing and Simulating Human Behaviour in the Built Environment
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary In order to model natural human behaviour, it is necessary to capture this behaviour. First, we will start out by modelling behaviour for specific situations, such as taking a seat in a theatre. To capture humanbehaviour, the following experiment is performed: Given a virtual environment, a sufficient number of subjects (real humans) are asked to execute a human task in this virtual environment (e.g. take a seat inthe theatre). Whenever the subject deviates from the shortest path, the system will ask for a clue why this is done. The hypothesis is that the combination of the motion paths and the clues for making/changing decisions will provide decision rules to make reliable predictions about human behaviour under the same conditions when using virtual persons. To test the hypothesis, we propose to use the university’s main conference and presentation hall as a test case. A 3D model and a motion pathgraph are constructed that enables a virtual person to find its way to a selected chair. The clues from the experiment are implemented as decision rules that determine a virtual person’s behaviour. Running thesimulation will result in the following data: Time per person to find a chair, Deviation from the shortest path, Distance covered per person to find a chair, Distribution of seated persons over time and Relocation of persons. To validate the test case, the process of people entering the hall and finding a chair is recorded on videotape. The walking behaviour of the people observed on the video is analysed and compared with the data from the simulation.

title Reinterpretation or replacement? The effects of the information and communication technologies on urban space
source CORP 2002, Vienna, pp. 345-349
summary The timid question “Virtual spaces or real places?” forms the core of many debates within the spatial sciences addressing theconsequences of the rapid development of information and communication technologies1 on existing spatial structures. So far several opinions rival each other for the interpretation of current and the prediction of future spatial developments. The spacelessness ofcomputer networks and the possibility to transmit data in real-time have lead visionaries to predict a far-reaching devaluation of timeand space, so questioning the future importance of traditional spatial structures: The “annihilation of distance and time constraints [incomputer networks] could undermine the very rationale for the existence of the city by dissolving the need for physical proximity”(Graham and Marvin 1996: 318). The disappearance of the city into the net, therefore, seems to become a distinct possibility.

title Instance and System: a Figure and its 2.18 Variations
source International Conference on Generative Art
summary From the structural characteristics of an existing figure - a graphical logo – a plausible solution space of related figures is constructed, which contains all other figures, which may be generated by systematically exploiting the structural characteristics of the input figure. The constructed space of figures can be understood to represent the solution space for the design of the logo. A designer, proceeding systematically by following some generative set of rules would have to construct this solution space at least to the point of a decision, if not entirely. In the presented experiment, this “solution space” will be exhausted completely and the resulting images (there are 218 will be outputted graphically. Questions will be asked concerning the design process, the generative rules, and the selection of the one instance representing a solution. The presented results are to be seen as “work in progress”.

title Arquitectura modular basada en la teoría de policubos [Modular Architecture Based on the Theory of Policubos]
source SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 264-267
summary Modular Architecture refers to the design of any system composed of separated components that can be connected together preserving proportional and dimensional relationships. The beauty of modular architecture is that it is possible to replace or add any component (a module) without affecting the rest of the system. A polycube is a set of unit cubes joined in such a way that each face of the cube is either completely joined to another or completely free of any join. A polycube is a 3D generalization of polyominoes, which consist in a set of squared unit modules joined by their sides. This paper shows how, from the volumetric and modular character of polycubes, it is possible to set correspondences with 3D forms of architectural use, being a very powerful sustain in assisted design processes. The main purposes are:- to be used as creative triggers in the realization of architectural designs- to enlarge the possibilities of CAAD systems exploring modular complex groupings- to develop a simplified procedure of teaching-learning architectural forms.

summary Despite increasing interest in the functionality and humanization of architecture, scarcely the occupation of buildings are studied and it lacks methods to represent activities in the spaces. By this reason, it proposes a system such integrates simulation of processes and virtual modeling software, to program the behavior of tri-dimensional characters based on the probabilistic evolution of events, testing this approach in the study of emergency services of hospitals. It describes the procedure developed and reflections about temporal representation, demonstrating that modeling of activities allows to suggest functional and spatial improvements.

title Free-form thick layer object manufacturing technology for large-sized physical models
source Automation in Construction 11 (3) (2002) pp. 335-347
summary Large-sized free-form objects of different materials are widely used in various industrial applications. Currently, layered rapid prototyping technologies are not suitable for the fabrication of this kind of objects, due to the necessity of a large number of layers and the limitations in size. This paper reports a novel approach of layered manufacturing that is more appropriate for the fabrication of these large objects. A method of thick-layered object manufacturing is presented, which is based on a higher order approximation of the shape and application of a flexible curved cutting tool. The method allows the production of physical prototypes, which need little or no finishing. In order to meet the designer's intend, as closely as possible, some feasible system characteristics are introduced. The process is ordered in a sequential way and provides a highly automated process. A hierarchical decomposition of the CAD geometry takes place into components, segments, layers and sectors, based on morphological analysis. This method enables the manufacturing and the re-assembly of the parts to produce the physical prototypes without affecting the requested functionality. Due to the possibility of obtaining multiple solutions in the physical model, much attention must be paid to the efficiency of the process.

source SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 133-139
summary Bases de datos, Sistemas y Redes 134The purpose of this report is to present the achievements obtained in the use of the technologies of information andcommunication in the architecture, by means of the construction of a database to register the information on the modernarchitecture of the city of Maracaibo from 1920 until 1990, in reference to the constructions located in 5 of Julio, Sectorand to the most outstanding planners for its work, by means of the representation of the same ones in digital format.The objective of this investigation it was to elaborate a database for the registration of the information on the modernarchitecture in the period 1920-1990 of Maracaibo, by means of the design of an automated tool to organize the it datesrelated with the buildings, parcels and planners of the city. The investigation was carried out considering three methodologicalmoments: a) Gathering and classification of the information of the buildings and planners of the modern architectureto elaborate the databases, b) Design of the databases for the organization of the information and c) Design ofthe consultations, information, reports and the beginning menu. For the prosecution of the data files were generated inprograms attended by such computer as: AutoCAD R14 and 2000, Microsoft Word, Microsoft PowerPoint and MicrosoftAccess 2000, CorelDRAW V9.0 and Corel PHOTOPAINT V9.0.The investigation is related with the work developed in the class of Graphic Calculation II, belonging to the Departmentof Communication of the School of Architecture of the Faculty of Architecture and Design of The University of the Zulia(FADLUZ), carried out from the year 1999, using part of the obtained information of the works of the students generatedby means of the CAD systems for the representation in three dimensions of constructions with historical relevance in themodern architecture of Maracaibo, which are classified in the work of The Other City, generating different types ofisometric views, perspectives, representations photorealistics, plants and facades, among others.In what concerns to the thematic of this investigation, previous antecedents are ignored in our environment, and beingthe first time that incorporates the digital graph applied to the work carried out by the architects of “The Other City, thegenesis of the oil city of Maracaibo” carried out in the year 1994; of there the value of this research the field of thearchitecture and computer science. To point out that databases exist in the architecture field fits and of the design, alsoweb sites with information has more than enough architects and architecture works (Montagu, 1999).In The University of the Zulia, specifically in the Faculty of Architecture and Design, they have been carried out twoworks related with the thematic one of database, specifically in the years 1995 and 1996, in the first one a system wasdesigned to visualize, to classify and to analyze from the architectural point of view some historical buildings of Maracaiboand in the second an automated system of documental information was generated on the goods properties built insidethe urban area of Maracaibo. In the world environment it stands out the first database developed in Argentina, it is the database of the Modern andContemporary Architecture “Datarq 2000” elaborated by the Prof. Arturo Montagú of the University of Buenos Aires. The general objective of this work it was the use of new technologies for the prosecution in Architecture and Design (MONTAGU, Ob.cit). In the database, he intends to incorporate a complementary methodology and alternative of use of the informationthat habitually is used in the teaching of the architecture. When concluding this investigation, it was achieved: 1) analysis of projects of modern architecture, of which some form part of the historical patrimony of Maracaibo; 2) organized registrations of type text: historical, formal, space and technical data, and graph: you plant, facades, perspectives, pictures, among other, of the Moments of the Architecture of the Modernity in the city, general data and more excellent characteristics of the constructions, and general data of the Planners with their more important works, besides information on the parcels where the constructions are located, 3)construction in digital format and development of representations photorealistics of architecture projects already built. It is excellent to highlight the importance in the use of the Technologies of Information and Communication in this investigation, since it will allow to incorporate to the means digital part of the information of the modern architecturalconstructions that characterized the city of Maracaibo at the end of the XX century, and that in the last decades they have suffered changes, some of them have disappeared, destroying leaves of the modern historical patrimony of the city; therefore, the necessity arises of to register and to systematize in digital format the graphic information of those constructions. Also, to demonstrate the importance of the use of the computer and of the computer science in the representation and compression of the buildings of the modern architecture, to inclination texts, images, mapping, models in 3D and information organized in databases, and the relevance of the work from the pedagogic point of view,since it will be able to be used in the dictation of computer science classes and history in the teaching of the University studies of third level, allowing the learning with the use in new ways of transmission of the knowledge starting from the visual information on the part of the students in the elaboration of models in three dimensions or electronic scalemodels, also of the modern architecture and in a future to serve as support material for virtual recoveries of some buildings that at the present time they don’t exist or they are almost destroyed. In synthesis, the investigation will allow to know and to register the architecture of Maracaibo in this last decade, which arises under the parameters of the modernity and that through its organization and visualization in digital format, it will allow to the students, professors and interested in knowing it in a quicker and more efficient way, constituting a contribution to theteaching in the history area and calculation. Also, it can be of a lot of utility for the development of future investigation projects related with the thematic one and restoration of buildings of the modernity in Maracaibo.

title The “Digital year for Architects” Experiences with an integrated teaching concept
source Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 88-95

summary The “digital year for architects” is an integrated course for graduate architecture students, that has been held since 1997 at Stuttgart University. Its concept is to link together traditional design teaching and working with computers. Three seminars and one design project are the framework of the course, in which the students are taught in design of e.g. image and space composition, typography, video, using virtual reality, theoretical basics for the final design project like information management or working environments, approximately a dozen software packages and finally a visionary design project. It has shown that the advantage of an integrated course compared to separate courses is the more intensive dealing with the project as well as achieving better skills when learning the new media. Not only because the project topics are different from usual architecture and more abstract, the main effect is to widen the students way of thinking and designing.
