title Progress Towards Multi-Criteria Design Optimisation Using Designscript With Smart Form, Robot Structural Analysis and Ecotect Building Performance Analysis"
source ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 47-56
summary Important progress towards the development of a system that enables multi-criteria design optimisation has recently been demonstrated during a research collaboration between Autodesk’s DesignScript development team, the University of Bath and the engineering consultancy Buro Happold. This involved integrating aspects of the Robot Structural Analysis application, aspects of the Ecotect building performance application and a specialist form finding solver called SMART Form (developed by Buro Happold) with DesignScript to create a single computation environment. This environment is intended for the generation and evaluation of building designs against both structural and building performance criteria, with the aim of expediently supporting computational optimisation and decision making processes that integrate across multiple design and engineering disciplines. A framework was developed to enable the integration of modeling environments with analysis and process control, based on the authors’ case studies and experience of applied performance driven design in practice. This more generalised approach (implemented in DesignScript) enables different designers and engineers to selectively configure geometry definition, form finding, analysis and simulation tools in an open-ended system without enforcing any predefined workflows or anticipating specific design strategies and allows for a full range of optimisation and decision making processes to be explored. This system has been demonstrated to practitioners during the Design Modeling Symposium, Berlin in 2011 and feedback from this has suggested further development.

title Bio-Origami: Form Finding and Evaluation of Origami Structures
source Achten, Henri; Pavlicek, Jiri; Hulin, Jaroslav; Matejovska, Dana (eds.), Digital Physicality - Proceedings of the 30th eCAADe Conference - Volume 1 / ISBN 978-9-4912070-2-0, Czech Technical University in Prague, Faculty of Architecture (Czech Republic) 12-14 September 2012, pp. 497-504
summary This paper presents a concept of origami as a form-generator for a structural system that allows deployability for structures with large spans. The presented approach studies the embedded kinetic possibilities of folded structures and focuses on a parametric modelling process that allows evaluating the structural performance of different types of the same origami family in order to optimize the geometry for a given scenario. The workfl ow between scripting based form generation – within Rhinoceros and Excel – and LS-DYNA is presented in detail. In addition to that the question of scalability from a thin microstructure to a thickened roof structure is discussed in the context of an architectural project.

title Computer simulation for intuitive structuring
source Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 369–378
summary Computer simulation methods have opened up new possibilities for design and research by introducing environments in which we can manipulate and observe. For instance, architects utilise three-dimensional modelling tools to simulate architectural geometries, and engineers use Finite Element software to simulate structural behaviour. Simulation tools make certain aspects of architecture efficient, but, on the other hand, they have brought new types of challenges into the field. One such challenge is the structuring of so-called complex geometries. These forms are often conceived in an environment where gravity, scales, and material are absent and calculated in a model where geometries are frozen and static. As a result, there exists little understanding between the two disciplines in solving the design to come to a well-negotiated form. In the context thereof, our work focuses on the development of interactive simulation environments that induce intuition towards the specific counter-intuitive problem of structuring in the early stages of design. The paper gives insights into aspects of simulation relevant to architectural design and structural engineering. Subsequently, three simulation environments that we have developed are presented to demonstrate our strategies.

summary This paper presents Architectural software Tool for Structural Analysis (ATSA) which is designed as a software bridge between architectural and structural software programmes. It has been developed at university in cooperation with architects and structural engineers, intended to make their interdisciplinary cooperation more efficient. ATSA is aimed to provide structural analysis of drafts created by an architetct in the early stages of design in order to enable the architect to understand the mechanical responses of the structure to loading, and thus optimise it creatively through an intuitive form-finding process.

title Interactive Form-Finding for Biomimetic Fibre Structures: Development of a Computational Design Tool and Physical Fabrication Technique Based on the Biological Structure of the Lichen
source Achten, Henri; Pavlicek, Jiri; Hulin, Jaroslav; Matejovska, Dana (eds.), Digital Physicality - Proceedings of the 30th eCAADe Conference - Volume 2 / ISBN 978-9-4912070-3-7, Czech Technical University in Prague, Faculty of Architecture (Czech Republic) 12-14 September 2012, pp. 519-529
summary This contribution shows a biomimetic approach to design and produce fibrous structural elements derived from the morphology of the biologic archetype ‘the lichen’. The physical form fi nding strategy allows for a novel self-organised reinforcement for fibrous composite systems. A computational design tool has been developed, based on the fi ndings of various physical models. The digital device allows for shape control and therefore an interaction to and manipulation of the fabrication process. Since the form fi nding algorithms of the tool are based on physical experiments,every geometry is derived through the program and has its counterpart in production. For example: the fibre density in the model can be adjusted which leads to different geometries. In production the chosen denseness is utilised, thus, the production yields automatically to the desired load-optimized geometry found in the form-finding tool.

title Tuning Heavy Design: Parametric Structural Form Generation

summary This paper discusses a methodology for generating architectural form parametrically from structural logics such that an architectural vocabulary can be generated for use in design. It intends to further the discussion of how parametrics can play a role in architectural design. Parametric applications are facilitating the use of engineering design feedback into the architectural process, allowing architects to ‘tune’ their designs. In this case, structural form is discussed. The nature of parametrics makes the use of structural principles relatively simple because they are already in the numeric form of equations. As well, parametrics make the generation of alternatives easy because of the iterative nature of the tool. As such, including the basis of structural principles in the logic of the parametrics allows the design to function performatively in both an architectural and a structural sense.

title Parallel Development of Parametric Design Models Using Subjunctive Dependency Graphs

summary Exploring problems through multiple alternatives is a key aspect of design. In this paper, we present a prototype system as an extension to existing parametric CAD tools that enables parallel generation and editing of design alternatives. The system is built on two fundamental ideas. First, use of subjunctive dependency graphs enables simultaneous work on multiple design variations. These graphs capture and reveal complex data flow across alternative parametric CAD models. Second, prototype-based modeling provides a weak notion of inheritance enabling incremental description of differences between alternatives. The system is intended to be general enough to be used in different CAD platforms and other systems using graph-based modeling. The three basic system functions are definition of alternatives (variations) using prototype-based modeling, structural and parametric divergences of the prototypes, and interactive comparison. The goal of this research is consistent with the general qualities expected from any creativity support tools: enabling exploration and simultaneous development of variations.

title A System for Collaborative Design on Timber Gridshells
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. 441–450
summary The bent timber laths of the Sound Bites gridshell create two types of performance space over an area of almost 100 m2. Such postformed gridshells are a wellestablished design solution for creating curved forms from linear elements. Extending principles developed since the 1970s, contemporary digital tools have been utilised to drive a renewed interest in them, primarily through so-called form-finding techniques which connect digital and material models through a simulation of shape under bending loads (Nettlebladt, 2013) and the definition of efficient structural geometry acting under compression loads only (Hernandez et. al., 2012). This paper describes the workflow conceived and implemented for the Sound Bites structure. A central challenge of the research was for such a workflow to allow for the principles of gridshell design to be engaged in parallel to other tight constraints and design drivers. As such it needed to facilitate close collaboration between architectural, engineering and fabrication experts. This workflow was tested in the design and realisation of the full-scale structure within a six-week period. The gridshell design was developed through the manipulation of the shape of two edge profiles and the shell form spanning between these. Architectural and fabrication constraints were met and the workflow allowed for a sufficient level of structural analysis to be fed back to inform the design.

title The Forbidden Symmetries

summary The emergence of quasi-periodic tiling theories in mathematics and material science is revealing a new class of symmetry, which had never been accessible before. Because of their astounding visual and structural properties, quasi-periodic symmetries can be ideally suited for many applications in art and architecture; providing a rich source of ideas for articulating form, pattern, surface and structure. However, since their discovery, the unique long-range order of quasi-periodic symmetries, is still posing a perplexing puzzle. As rule-based systems, the ability to algorithmically generate these complicated symmetries can be instrumental in understanding and manipulating their geometry. Recently, the discovery of quasi-periodic patterns in ancient Islamic architecture is providing a unique example of how ancient mathematics can inform our understanding of some basic theories in modern science. The recent investigation into these complex and chaotic formations is providing evidence to show that ancient designers, by using the most primitive tools (a compass and a straightedge) were able to resolve the complicated long-range principles of ten-fold quasi-periodic formations. Derived from these ancient principles, this paper presents a computational model for describing the long-range order of octagon-based quasi-periodic formations. The objective of the study is to design an algorithm for constructing large patches of octagon-based quasi-crystalline formations. The proposed algorithm is proven to be successful in producing an infinite and defect-free covering of the two-dimensional plane.

title Digital conception(s): Architectural concepts of digital design and making
source Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 699–708
summary This paper presents an investigation of probative works of architectural thought and production executed in various forms of digital design and computational media. The applied design research focuses on an examination of the procedure or process constructed to both develop exact, precise digital models and constructed processes that result in design outcomes that cannot be pre-visioned. The changing position of the conceptualisation within the design process continually changes the relationship of the digital work and the computational framework. The work challenges one to interpret design processes of translation and transformation, through the continual oscillation between developed in pursuit of known results and constructed methods for making, in an effort to unravel the pretext of the singular point of view to reveal the intention of the design conception(s). The projects discussed here focus on relationships between the projection of space in architectural representation and the production of architectural form through complex geometries relative to discontinuities and the way in which they agitate and alter one another. DIGITAL conception(s) operate across three primary areas of research; animation, conceptualisation and fabrication. The work oscillates between digital and physical artefacts that intertwine digital/physical workflows while simultaneously engaging temporal issues of time based media through motion graphics and animate constructs.

title Crowdsourcing Architecture: A Disruptive Model in Architectural Practice

summary This paper discusses the use of crowdsourcing as a new approach for architectural design acquisition. We will give an overview of the concept of crowdsourcing, and elaborate on its particular application in architecture via concrete projects executed on Arcbazar, a firstof- its-kind crowdsourcing platform for architectural design services. We argue that online crowdsourcing platforms can have an immense impact on smaller-scale design challenges, e.g., home remodeling projects and landscape and interior design challenges, and can potentially carry these often neglected projects into the architectural design sphere. In this paper we will discuss the methods and techniques of architectural crowdsourcing and illustrate the processes and outcomes through a series of projects: a remodeling project for a closet; an interior design challenge for a dining space; and a layout problem for an apartment complex. We will then evaluate the protocol and outcome of architectural crowdsourcing, and convey the professional and popular media response to this new method of architectural design acquisition.

summary Architecture today has come to its most complex form. There are lots of criteria such as fi re safety, structure, sustainability etc… which must be controlled by the designers. To improve the performance and accessibility of buildings, governing bodies publish different codes for each of the different criteria. Buildings must comply with these codes to get a permit for construction. The checking of the buildings according the codes is done manually by code offi cials. This process is time consuming, high in cost and prone to errors. To remedy this problem by using the tools like BIM and AI, systems that can automatically check the code compliance of projects are being developed. In this paper we provide an overview of the structures and capabilities of these systems and present the automated code compliance checking system that we develop for checking building models against some parts of the Turkish Fire Codes.

title Zero-Waste, Flat-Packed, Tri-Chord Truss: Continued Investigations of Structural Expression in Parametric Design"
source ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 199-208
summary The direct and rapid connections between scripting, modeling and prototyping allow for investigations of computation in fabrication. The manipulation of planar materials with two-dimensional CNC cuts can easily create complex and varied forms, volumes, and surfaces. However, the bulk of research on folding using CNC fabrication tools is focused upon surfaces, self-supporting walls and shell structures, which do not integrate well into more conventional building construction models. This paper attempts to explain the potential for using folding methodologies to develop structural members through a design-build process. Conventional building practice consists of the assembly of off-the-shelf parts. Many times, the plinth, skeleton, and skin are independently designed and fabricated, integrating multiple industries. Using this method of construction as an operative status quo, this investigation focused on a single structural component: the truss. Using folding methodologies and sheet steel to create a truss, this design investigation employed a recyclable and prolific building material to redefine the fabrication of a conventional structural member. The potential for using digital design and two-dimensional CNC fabrication tools in the design of a foldable truss from sheet steel is viable in the creation of a flat-packed, minimal waste structural member that can adapt to a variety of aesthetic and structural conditions. Applying new methods to a component of the conventional ‘kit of parts’ allowed for a novel investigation that recombines zero waste goals, flat-packing potential, structural expression and computational processes. This paper will expand (greatly) upon previous research into bi-chord truss designs, developing a tri-chord truss, which is parametrically linked to its structural moment diagram. The cross section of each truss is formed based on the loading condition for each beam. This truss design has been developed through a thorough series of analytical models and tests performed digitally, to scale and in full scale. The tri-chord truss is capable of resisting rotational failures well beyond the capacity of the bi-chord designs previously developed. The results are complex, and elegant expressions of structural logics embodied in a tightly constrained functional design.

summary As host organizers of the Smartgeometry 2012 Conference, professors of Architecture, and as principals in design firms, our work aims to use as a productive resistance the notion of Material Intensity described below as both a foil and measure to current concepts of simulation and intensive modeling in architectural computation. The holding of SG 2012 aimed to stage this resistance in the form of workshop, round-table discussions, lectures and symposia, with the outcome attempting to define a new synthetic notion of material intensities in modes of architectural production. This paper aims to form the basis of a continued exploration and development of this work. In summary we focused on: 1-Intensive thinking as derived from the material sciences as an actual and philosophical framework that emphasizes qualitative attributes, which is likened to behavior, simulation, and dynamic modeling. Extensive attributes lead to analytical, representational and static modeling. 2-Material practices can also be formed and as a result of this method of thinking. As demonstrated by the glasswork of Evan Douglis, ‘paintings’ by Perry Hall—the managed complexity possible by working with materials during intensive states of change allow for scalar, morphological and performative shifts according to a designer’s criteria. 3- Although both are necessary and actually complement each other, architects need to ‘catch-up’ to intensive thinking in process and modeling strategies. Our methods rely on static modeling that yield often complicated frameworks and results, wherein accepting methods of dynamic modeling suggests the capacity to propose complex and nuanced relationships and frameworks.

The study is a part of a PhD research that focuses on investigating computer-aided software to develop a virtual route for electric mobility in the North Sea Region. An overview of agent-based simulation platforms is discussed. Electric mobility system has particular paradigms that differ from conventional urban transport systems; a comparison is presented followed by the recommended approach of integrating the two techniques (visualization and simulation). Finally, the architecture of agents’ algorithm within the EVs network is presented through a case study of virtual Newcastle-Gateshead model.

summary Integral structural optimization and fabrication seeks the synthesis of two original approaches; that of topological optimization (TO) and robotic hotwire cutting (HWC) (Mcgee 2011). TO allows for the reduction of up to 70% of the volume of concrete to support a given structure (Sondergaard & Dombernowsky 2011). A strength of the method is that it allows to come up with structural designs that lie beyond the grasp of traditional means of design. A design space is a discretized volume, delimiting where the optimization will take place. The number of cells used to discretize the design space thus sets the resolution of the TO. While the approach of the application of TO as a constitutive design tool centers on structural aspects in the design phase (Xie 2010), the outcome of this process are structures that cannot be realized within a conventional budget. As such the ensuing design is optimal in a narrow sense; whilst optimal structurally though, construction can be prove to be prohibitively expensive.

This paper examines these problems as well as possible solutions for the design of a completed and built prototype using the example of an organically shaped pavilion made of glass fi bre reinforced plastic modules. The paper describes which adjustments to the original design were required to take the step from “digital physicality” to “physical digitality” to realize a constructive and economically successful implementation. The solutions discussed combine modern digital software methods such as parametric design with innovative 3D modelling principles.

title Fabricating Sustainable Concrete Elements: A Physical Instantiation of the Marching Cubes Algorithm
source ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 239-247
summary This paper explores how an algorithm designed to represent form can be made physical, and how this physical instantiation can be made to respond to a set of design imperatives. Specifically, the paper demonstrates how Marching Cubes (Lorensen and Cline 1987), an algorithm that extracts a polygonal mesh from a scalar field, can be used to initiate the design for a system of modular concrete armature elements that permit a large degree of variability using a small number of discrete parts. The design of these elements was developed in response to a close examination of Frank Lloyd Wright's Usonian Automatic system, an architecturally pertinent historical precedent. The fabricated results positively satisfy contemporary design criteria, including maximal formal freedom, optimal environmental performance, and minimal life-cycle costs.

title Toward a performance-oriented architecture: An integrated design approach to a real time responsive structure
source Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 59–68
summary This paper started from the study of “performance-oriented architecture” for the purpose of developing a real time responsive prototype that can enclose large expansive interior space. Questions regarding the relationship between the structural arrangement of systems and the natural environment initiated an investigation in Phyllotaxis. It has been found in plant systems for the optimisation of photosynthesis with harvesting maximum amounts of solar energy. In the design of a real time responsive prototype, an algorithmic approach is introduced with the mathematical interpretation of Phyllotaxis and its translation into the global geometry of the prototype. Also, the usage of a Voronoi diagram is parametrically configured to form the local geometry of the prototype. The interactive mechanism of the prototype was achieved with an assorted computational application. Furthermore, with the demonstration of the aforementioned prototype in both digital and physical environments, its implementation process is explained.
