title Material Systems: A Design Approach
source Computation: The New Realm of Architectural Design [27th eCAADe Conference Proceedings / ISBN 978-0-9541183-8-9] Istanbul (Turkey) 16-19 September 2009, pp. 721-728
summary This paper describes and reflects upon the results of an investigative project which explores the setting up of a material system – a parametric and generative assembly consisting of and taking into consideration material properties, manufacturing constraints and geometric behavior. The project approaches the subject through the construction of a logic-driven system aiming to explore the possibilities of a material system that fulfills spatial, structural and performative requirements concurrently and how these are negotiated in situations where they might be conflicting.

title The generation of possible space layouts
source Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 1, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 239-246
summary The general scope of this paper is to present the development of an approach for the generation of possible space layouts in the early stages of design. The approach sets out to bridge the gap between the free form brainstorming of the sketching designer and the deterministic parametric model of the computational designer. A new responsive design tool is developed; applying physical based modelling techniques to a computational environment. Springs and particles automates the initial placement and sizing of the spaces, and allows continuous user and software interaction. Keeping the design process alive, through springs that connects everything to everything and allows topology to change, opposed to the strict hierarchy and constraints of traditional parametric design. Thus instead of the topology being determined by initial constraints, the layout will be generated by probabilities of spaces to connect. Letting the storyline of potential users give answers to possible space layouts.

title Visualizing Simulated Construction Operations in 3D
source Journal of Computing in Civil Engineering -- October 2001 -- Volume 15, Issue 4, pp. 329-337
summary Simulation modeling and visualization can substantially help in designing complex construction operations and in making optimal decisions where traditional methods prove ineffective or are unfeasible.However, there has been limited use of simulation in planning construction operations due to the unavailability of appropriate support tools that can provide users with a more realistic and comprehensiblefeedback from simulation analyses. Visualizing simulated construction operations in 3D can significantly help in establishing the credibility of simulation models. 3D visualization can also provide valuableinsight into the subtleties of construction operations that are otherwise nonquantifiable and presentable. This paper describes the methodology and a first version of a general-purpose 3D visualization system thatis simulation and CAD software independent. This system, the Dynamic Construction Visualizer, enables spatially and chronologically accurate 3D visualization of modeled construction operations and theresulting products.

title Floder: A Floor Designer Expert System
source Department of Civil Engineering, Carnegie Mellon University, Pittsburgh PA
summary The use of computers in structural design for the last two decades has been limited to algorithmic and procedural tasks. The use of expert system environments facilitates the implementation of conceptual tasks in computer programs. The goal of this study is to develop an expert system for the structural design of floor framings. FLODER, the resulting expert system, generates, analyzes, and evaluates floor framings for a given architectural plan. Framing generation consists of determination of the locations of structural elements in the architectural plan. Analysis involves an approximation of the dimensions of the slabs. Evaluation numerically ranks all generated framings using heuristic features for the alternatives. FLODER is implemented in OPS5 and LISP. The primary representations used are OPS5 production rules for the knowledge-base, and OPS5 working memory elements, for the context. Tasks amenable to algorithmic approaches are implemented in LISP. FLODER, even in its present state, can be viewed as a useful assistant to a designer. It can rapidly generate and evaluate alternative framings for a given architectural plan and thus increase the work productivity of its users [includes bibliography].

title Forming and automated energy analysis of integrated models of the public buildings and their enclosing structures
source Civil Engineering, 6(3), pp. 147-157
summary The article concerns the modelling and energy analysis problem of the spatial and structural solutions of newly designed buildings or those under renovation. The results of that task serve as a base for defining thermal indices of the project on different design stages. The core of the developed automated system is formed of integrated graphical digital spatial models of the parts of buildings. These models include different kind of structured geometric and non-geometric (physical, economical) information about the object. The proposed method could be used by interested experts as a tool for controll thermal and energy indices at various design stages, searching for rational architectural forms and structural solutions. It takes into account the latest requirements of Lithuanian building regulations concerning heating energy saving.

title A standards processing framework
source Carnegie Mellon University, Pittsburgh
summary Civil engineers create and employ a very large number of design standards, especially in the United States. Designing using such a large number of design standards is a tedious, laborious, and difficult task. One major research task in Computer-Aided Engineering (CAE) is the development of software tools that assist in the usage of design standards during the design process. This dissertation, a standards processing framework is presented. It is an agent-based approach to providing computer-aided support for using design standards. In this framework, modules, such as standards processing servers, are treated as agents communicating using a defined communication language. One immediate advantage of this architecture is that it allows the incorporation of a broad, powerful set of representation for use in modeling design standards.

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 Digitized Planning Processes in the Revitalization of Buildings by an Interdisciplinary Project Study
source Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 717-723
summary In the curricula for students of civil engineering and architecture software training courses have been integrated for long, but didactical training concepts with an application in practice including both the constructional and planning aspects are missing. This conference contribution shows the result of a research work carried out to empirically develop a manual for a constructional, digitally supported project work. It comprised the interdisciplinary teaching with a special focus on two examples of buildings in situ. Different types of presentation, picture software and CAD were used from the very beginning of the planning process in order to create a new form of didactics in teaching and learning. The basic local parameters and approaches are documented and analyzed. As a result of the empirical research work presented herein a manual was developed which is useful as a guideline for the digital interdisciplinary project development in the revitalization of buildings. It reflects the experiences gained in this empirical research work and formulates the steps to take to carry out the project. The paper is presented with a 3-D-video projection on the basis of stereoscope pictures.

In this context, we investigate the current options for setting up and distributing video-based online courses. First, we make a review of a subjectively selected set of existing platforms and technologies for video-based online courses. Next, we discuss the needs of futures online teaching concepts and the corresponding challenges of digitalization for university teaching. We summarize essential aspects of the considered platforms, technologies, and today's examples in tables. The main result is an overview of systems that can be used to start your online teaching initiative with a small budget.

title DEFINITION OF A METHOD OF LIMITS OF THE SIMPLIFICATION OF A HALL MODEL IN A CAD SYSTEM TO DIMINISH FALSIFICATION OF ACOUSTIC SIMULATION RESULTS
source International Congress eCAADe 2005 (Education and research in Computer Aided Architectural Design in Europe), subject : “Digital Desing : the quest for new paradigms”, ISBN 0-9541183-2-4, pp. 695-704, Technical University of Lisbon, Portugal, 21-24 September 2005
summary During the modelling, because of the sometimes complex architectural shape of halls, we were forced to introduce simplifications in order to carry out calculations and simulation operations on these halls, as the calculation software requires plane surfaces. This paper presents a developed tool adapted on a CAD modelling system (AutoCAD), which defines an “average limits” of the model simplification operation in order to control and diminish the falsification of calculation and simulation results on this model, such as the architectural acoustic simulation. The process of the elaboration and the adjustment of the simplified models of the Grand Theatre of Bordeaux (GTB) based on acoustical measurements and their calculation results are described in detail in a previous article (Kouzeleas and Semidor, 2001). The analysis process of the consequences of the hall model simplification on the acoustical simulation results and the applied simplification methods are described in a PhD thesis (Kouzeleas, 2002). This article is based on this analysis process in order to apply it on several simplified models of the Amphitheatre of the Architecture School of Bordeaux (Amphi-EAPB). The comparison in a CAD system (AutoCAD) of the acoustical calculation results and the areas after simplification of the simplified models of these two halls made with AutoCAD, via the developed tool adapted on the AutoCAD, permit to define a “limits average of a hall model simplification” before the falsification of these calculation results.

summary A high percentage of overall defects in the built environment occurs during the construction period. Some of these relate to design and the others relate to construction. The detection and reasoning of defects requires involvement of multiple expertise. Researchers in the School of Architecture, the Robotics Institute, and the Department of Civil and Environmental Engineering at Carnegie Mellon University are investing ways to integrate suites of emerging evaluation technologies to help find, record, manage, and limit the impact of construction defects. As part of this effort, the researchers have conducted case studies on construction sites near Pittsburgh, Pennsylvania. Each case study serves as a test-bed to measure the feasibility of our approach and to discover problems. In this paper, we discuss the overall project work flow in which we emphasize the importance of a flexible representation for construction, and describe our solution using a concept of representational flexibility named sorts.

title A Computational Tool for Evaluation of Seismic Performance of RC Buildings
source February, 1990. [1] 15 p. : ill. graphs, tables. includes bibliography: p. 10-11
summary Recent events have demonstrated the damaging power of earthquakes on structural assemblages resulting in immense loss of life and property (Mexico City, 1985; Armenia, 1988; San Francisco, 1989). While the present state-of-the-art in inelastic seismic response analysis of structures is capable of estimating response quantities in terms of deformations, stresses, etc., it has not established a physical qualification of these end-results into measures of damage sustained by the structure wherein system vulnerability is ascertained in terms of serviceability, repairability, and/or collapse. An enhanced computational tool is presented in this paper for evaluation of reinforced concrete structures (such as buildings and bridges) subjected to seismic loading. The program performs a series of tasks to enable a complete evaluation of the structural system: (a) elastic collapse- mode analysis to determine the base shear capacity of the system; (b) step-by-step time history analysis using a macromodel approach in which the inelastic behavior of RC structural components is incorporated; (c) reduction of the response quantities to damage indices so that a physical interpretation of the response is possible. The program is built around two graphical interfaces: one for preprocessing of structural and loading data; and the other for visualization of structural damage following the seismic analysis. This program can serve as an invaluable tool in estimating the seismic performance of existing RC buildings and for designing new structures within acceptable levels of damage

source Automation in Construction 4 (1) (1995) pp. 61-73
summary There are various important outdoor applications in the fields of civil engineering, environmental technology or catastrophy management which require the introduction of a large range robot. In collaboration with industrial partners the KfK has developed such Extended Multi joint Robot (EMIR) which is driven by hydraulic actuators. The position control of EMIR is a tough problem due to the extreme nonlinearities of the kinematics and hydraulic actuators as well as the remarkable elasticities of the mechanics and hydraulics. In the first part of this paper a realistic physically transparent model of the robot will be presented. In the second part different suitable control concepts based on the model will be discussed.

title The Age of Spiritual Machines: When Computers Exceed Human Intelligence
source Penguin Books, London
summary How much do we humans enjoy our current status as the most intelligent beings on earth? Enough to try to stop our own inventions from surpassing us in smarts? If so, we'd better pull the plug right now, because if Ray Kurzweil is right, we've only got until about 2020 before computers outpace the human brain in computational power. Kurzweil, artificial intelligence expert and author of The Age of Intelligent Machines, shows that technological evolution moves at an exponential pace. Further, he asserts, in a sort of swirling postulate, time speeds up as order increases, and vice versa. He calls this the "Law of Time and Chaos," and it means that although entropy is slowing the stream of time down for the universe overall, and thus vastly increasing the amount of time between major events, in the eddy of technological evolution the exact opposite is happening, and events will soon be coming faster and more furiously. This means that we'd better figure out how to deal with conscious machines as soon as possible--they'll soon not only be able to beat us at chess, they'll likely demand civil rights, and they may at last realize the very human dream of immortality. The Age of Spiritual Machines is compelling and accessible, and not necessarily best read from front to back--it's less heavily historical if you jump around (Kurzweil encourages this). Much of the content of the book lays the groundwork to justify Kurzweil's timeline, providing an engaging primer on the philosophical and technological ideas behind the study of consciousness. Instead of being a gee-whiz futurist manifesto, Spiritual Machines reads like a history of the future, without too much science fiction dystopianism. Instead, Kurzweil shows us the logical outgrowths of current trends, with all their attendant possibilities. This is the book we'll turn to when our computers

summary Virtual studios have provided a valuable content in which to explore and test approaches to both collaborative design and pedagogy. While there has been extensive earlier experience in virtual campuses; not least that at The Open University in England; virtual design studios have explored a different nature of collaboration and interaction; shedding light on a new range of tasks and methods. These lessons have been applied in many fields. For example; the lessons have been used to understand the nature of collaboration. Most directly; they have been applied to the context of teaching design and understanding better how students learn to design. The change in technology can open up new opportunities in what is taught; not only how it is taught. Most broadly; they have been taken in to consideration in the creation of virtual campuses for broader university teaching. All these aspects are explored in this paper.

summary This paper presents the results of an exploratory study developed with the Autodesk Project Vasari and AutoCAD Civil 3D. Project Vasari was used to evaluate the environmental performance of a low-income housing project. It shows us that the actual site orientation of the project presents poor environmental performance, which could be improved by rotating building in 90 degrees. The AutoCAD Civil 3D was used to evaluate how that rotation should impact on earthmoving. The results showed that the simulations developed, even though having low level of accuracy, provide sufficiently clear information to support decision making on conceptual mass project stage.
