title	Reconfiguring Architectural Space using Generative Design and Digital Fabrication: A Project Based Course
source	SIGraDi 2013 [Proceedings of the 17th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-956-7051-86-1] Chile - Valparaíso 20 - 22 November 2013, pp. 391 - 395
summary	This paper discusses a course that addresses the integration between generative design and digital fabrication in the context of reconfiguring architectural space. The objective of the course, offered for 3rd year architecture students at the Department of Architecture, Ain Shams University, Egypt, was to design and fabricate interior design elements to be installed within the department lobby. Students worked in digital and physical environments to develop 8 group projects that featured concepts of shape grammars, L-systems, fractals and cellular automata. The potential of the realized projects is discussed in terms of 3D development of systems, contextual generative design, and pedagogical objectives.

title	Frameworks for Computational Design of Textile Micro-Architectures and Material Behavior in Forming Complex Force-Active Structures
doi	https://doi.org/10.52842/conf.acadia.2013.281
source	ACADIA 13: Adaptive Architecture [Proceedings of the 33rd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-926724-22-5] Cambridge 24-26 October, 2013), pp. 281-292
summary	Material behavior can be defined as the confluence of associative rules, contextual pressures and constraints of materialization. In more general terms, it can be parameterized as topologies, forces and materiality. Forming behavior means resolving the intricate matrix of deterministic and indeterministic factors that comprise and interrelate each subset of these material- nherent conditions. This requires a concise design framework which accumulates the confluent behavior through successive and cyclical exchange of multiple design modes, rather than through a single design environment or set of prescribed procedures. This paper unfolds a sequencing of individual methods as part of a larger design framework, described through the development of a series of complex hybrid- structure material morphologies. The “hybrid” nature reflects the integration of multiple force-active structural concepts within a single continuous material system, devising both self-organized yet highly articulated spatial conditions. This leads primarily to the development of what is termed a “textile hybrid” system: an equilibrium state of tensile surfaces and bending-active meshes. The research described in this paper looks to expose the structure of the textile as an indeterministic design parameter, where its architecture can be manipulated as means for exploring and differentiating behavior. This is done through experimentation with weft-knitting technologies, in which the variability of individual knit logics is instrumentalized for simultaneously articulating and structuring form. Such relationships are shown through an installation constructed at the ggggallery in Copenhagen, Denmark.

title	Morphological Behavior of Shape Memory Polymers Toward a Deployable, Adaptive Architecture
doi	https://doi.org/10.52842/conf.acadia.2013.121
source	ACADIA 13: Adaptive Architecture [Proceedings of the 33rd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-926724-22-5] Cambridge 24-26 October, 2013), pp. 121-128
summary	Shape-memory polymers (SMPs) are an emerging class of “smart materials” that have dual-shape capability. They are able to undergo significant deformation when exposed to an external stimulus such as heat or light. SMPs have been widely investigated within the biomedicine and aerospace industries; however, their potential has yet to be explored within an architectural framework. The research presented in this paper begins an investigation into the morphological behavior ofSMPs toward a deployable, adaptive architecture. The structure’s ease of assembly, compact storage, transportability and configurable properties offer promising applications in emergency and disaster relief shelters, lightweight recreational structures and a variety of other applications in the temporary construction and aerospace industry. This paper explores the use of SMPs through the development of a dynamic actuator that links a series of interconnected panels creating overall form to a self-standing structure. The shape-shifting behavior of the SMP allows the dynamic actuator to become flexible when storage and transportability are required. Alternatively, when exposed to the appropriate temperature range, the actuator is capable of returning to its memorized state for on-site deployment. Through a series ofprototypes, this paper will provide a fundamental understanding of the SMP’s thermo-mechanicalproperties toward deployable, adaptive architecture.

summary	Although commonly considered problematic within the wider range of standardized isotropic construction materials, wood’s mechanical deficiencies are simultaneously an asset for the adventurous designer. These anisotropic and organic characteristics can be critically investigated, even exaggerated, with the possibility of productively yielding a complex and adaptive building material.Given wood’s fibrous make-up, as derived from its ecological function as an evaporative capillary system, wood as a material is predisposed to react to environmental and contextual fluctuations—moisture in particular. As a consequence of its cellular and chemical anatomy, wood—unlike other standard construction materials—will morphologically react to changes in moisture. This reactivity is derived from interactions such as rehydration and swelling at the cellular level which accumulate to induce formal transformations at the macro level. This responsiveness, when coupled with the affordances of industrial standardization, reframes wood within architecture as a reactive material capable of consistent transformation well-suited to parametric definition within computational modeling.

title	Biomimetic Strategies in Tower Design

summary	The paper argues that the tower needs to respond to its environment by changing from a closed building typology towards a heterogeneous, differentiated open system that can adapt to the changing conditions within and around it. This argument is supported by focusing on the analogies and principles of specific biological examples in order to propose computationally-generated self-organizing systems. The goal of analyzing these models is to integrate their structural and geometrical characteristics with the aim of overcoming high lateral loading conditions in towers, as well as elaborating on the existence of multi-functionality and integration throughout the subsystems of the tower. A series of computational models which abstract the biological properties and articulate them with a generative approach through the use of agent-based systems are implemented according to designated evaluation criteria.

title	A Morphogenetic Approach for Performative Building Envelope Systems Using Leaf Venetian Patterns
doi	https://doi.org/10.52842/conf.ecaade.2013.1.497

summary	Recent developments in theory and technology in performance based design show an interest towards generative systems. In this paper a morphogenetic approach will be introduced that looks at Goethean morphology and leaf venation patterns. To instrumentalize this approach an algorithm will be introduced to generate various leaf venation patterns on complex mesh surfaces. As a case study, the paper tests the applicability of such system as performative algorithms for building envelopes. The role of simulation is to generate self-organizing forms and provide a framework for design development. The overall approach is to consider performance as a direct input to guide the computation of form at an early design stage.

title	Resilient Structures Through Machine Learning And Evolution
doi	https://doi.org/10.52842/conf.acadia.2013.319
source	ACADIA 13: Adaptive Architecture [Proceedings of the 33rd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-926724-22-5] Cambridge 24-26 October, 2013), pp. 319-326
summary	In the context of the growing usefulness of computation within architecture, structures face the potential for being conceived of as intelligent entities capable of resilient, adaptive behavior.Building on this idea, this work explores the use of machine learning for structures that may learn to autonomously “stand up”. The hypothesis is that a neural network with genetically optimized weights would be capable of teaching lightweight, flexible, and unanchored structures to self-rectify after falling, through their interactions with their environment. The experiment devises a physical and a simulated prototype. The machine-learning algorithm is implemented on the virtual model in a three-dimensional physics environment, and a solution emerges after a number of tests. The learned behavior is transferred to the physical prototype to test its performance in reality. This method succeeds in allowing the physical prototype to stand up. The findings of this process may have useful implications for developing embodied dynamic structures that are enabled with adaptive behavior.

summary	Previous research dealt with the problem of successfully approaching the combination of multiple, marginally compatible, historical and other forms of digital abstract data. The initial challenge, from a designer’s point of view, was to define and create the database for the Museum of the City of Volos (MuCiV) that will contain these seemingly incompatible data to a formulation collaborated with a geo-referenced information visualization system. This paper aims to go a step further by defining and implementing such an information visualization system. Thus, visual structures digitally representing a variety of non-spatial data, as well as the ways that these structures can interact, are investigated. It is argued that the results of this research can have interesting implementations to the museum program; by organizing in alternative ways its content and context and by facilitating the dissemination of information to the public through interactive multimodal exhibits.

Online and Global. 24-30 October 2020. edited by B. Slocum, V. Ago, S. Doyle, A. Marcus, M. Yablonina, and M. del Campo. 340-349.
summary	This paper presents the design, control system, and elastic behavior of ELAbot: a robotic bending active textile hybrid (BATH) structure that can self-form and transform. In BATH structures, equilibrium emerges from interaction between tensile (form active) and elastically bent (bending active) elements (Ahlquist and Menges 2013; Lienhard et al. 2012). The integration of a BATH structure with a robotic actuation system that controls global deformations enables the structure to self-deploy and achieve multiple three-dimensional states. Continuous elastic material actuation is embedded within an adaptive cyber-physical network, creating a novel robotic architectural system capable of behaving autonomously. State-of-the-art BATH research demonstrates their structural efficiency, aesthetic qualities, and potential for use in innovative architectural structures (Suzuki and Knippers 2018). Due to the lack of appropriate motor-control strategies that exert dynamic loading deformations safely over time, research in this field has focused predominantly on static structures. Given the complexity of controlling the material behavior of nonlinear kinetic elastic systems at an architectural scale, this research focuses on the development of a cyber-physical design framework where physical elastic behavior is integrated into a computational design process, allowing the control of large deformations. This enables the system to respond to conditions that could be difficult to predict in advance and to adapt to multiple circumstances. Within this framework, control values are computed through continuous negotiation between exteroceptive and interoceptive information, and user/designer interaction.

summary	Log Knot, developed by the Robotic Construction Laboratory (RCL) at Cornell University, is a robotically fabricated architectural installation that establishes a method for variable compound timber curvature creation utilizing both regular and irregular roundwood geometries. Moreover, the project develops methods for minimal formwork assembly and moment force optimization of customized mortise and tenon joints. Following the logic of a figure-8 knot, the project consists of an infinite loop of roundwood, curving three-dimensionally along its length. There are a variety of techniques to generate single curvature in wood structures – such as steam bending (Wright et al., 2013) or glue lamination (Issa and Kmeid, 2005) – but only a few techniques to generate complex curvature from raw material within a single wooden structural element exist. To construct complex curvature, the research team developed a simple method that can easily be replicated. First, the log is compartmentalized, establishing a series of discrete parts. Second, the parts are reconfigured into a complex curvature “whole” by carefully manipulating the assembly angles and joints between the logs. Timber components reconfigured in such a manner can either follow planar curvature profiles or spatial compound curvature profiles. Based on knowledge gained from the initial joinery tests, the research team developed a custom tri-fold mortise and tenon joint, which is self-supportive during assembly and able to resist bending in multiple directions. Using the tri-fold mortise and tenon joint, a number of full-scale prototypes were created to test the structural capacity of the overall assembly. Various structural optimization protocols are deployed in the Log Knot project. While the global knot form is derived from spatial considerations – albeit within the structurally sound framework of a closed-loop knot structure – the project is structurally optimized at a local level, closely calibrating structural cross-sections, joinery details, and joint rotation in relation to prevailing load conditions.

summary	This paper presents an innovative approach to the design and fabrication of three-dimensional objects from single-piece flat sheets, inspired by the origami technique of twist-closing. While in origami twist-closing is merely used to stabilize a cylindrical or spherical structure, ensuring it maintains its shape, this research investigates the potential of twist-closing as a multi-functional mechanism that also activates and controls the transformation of a planar surface into a predesigned three-dimensional form. This exploration is directed towards an intended application to stiff and brittle sheet materials that are difficult to shape through other processes. The methods we have developed draw mainly upon principles of lattice kirigami and laminar reciprocal structures. These are reflected in a workflow that integrates digital form-generation and fabrication-rationalization techniques to reference and apply these principles at every stage. Significant capabilities of the developed methodology include: (1) achievement of pseudo-double-curvature with brittle, stiff sheet materials; (2) stabilization in a 3D end-state as a frameless self-contained single-element laminar reciprocal structure—essentially a compliant mechanism; and (3) an ability to pre-encode 3D assembly constraints in a 2D cutout pattern, which guides a moldless fabrication process. The paper reviews the precedent geometric techniques and principles that comprise this method of 3D surface fabrication and describes a sample deployment of the method as applied to the design of laminar modules made of high-pressure laminate (HPL).

summary	This study applies self-organization as a methodology to understand the complex process of city networks caused by interactions between spatial structures and individual behaviors. The agent-based simulations have been conducted to investigate the visible and invisible networks understanding the self-organized aspects of city development processes. To develop optimal future networks providing connectivity and accessibility this study investigates spatial network configurations from internal individual behavior and movement. As results, it was found that the spatial configurations of the agent movement trails match to the current district boundaries and the similar network patterns were seen in various control values of agent behavior settings. This study contributes to searching out the hierarchy of network structures which is an important factor for re-planning of the way system.

summary	This paper introduces a series of design and fabrication tests directed towards the use of bendable 3D printing materials in order to simplify a foam bubble-based geometry as a frame structure for modular assembly. The aspiration to reference a spittlebug's bubble cocoon in nature for a light installation in the urban context was integrated into a computational workflow conditioning light-weight, material-, and cost savings along with assembly-simplicity. Firstly, before elaborating on the project motivation and background in foam structures and applications of 3D-printed thermoplastic polyurethane (TPU) material, this paper describes the physical nature of bubble foams in its relevant aspects. Subsequently this is implemented into the parametric design process for an optimized foam structure with Grasshopper clarifying the need for flexible materials to enhance modular feasibility. Following, the additive manufacturing iterations of the digitally designed node components with TPU are presented and evaluated. Finally, after the test assembly of both components is depicted, this paper assesses the divergence between natural foams and the case study structure with respect to self-organizing behavior.

summary	This paper introduces a potential application of construction systems seen in biological systems to overcome various shortcomings in human architecture. Unlike human constructions, some social insects can produce habitable structures with simple rules without predetermined blueprints or central leaders to gain more adaptability. Active application of logics from self-organizing systems can possibly enhance our conventional centralized methods by designing artificial distributed systems. A conceptual case study is presented that involves a notion of the collective construction.

summary	This paper demonstrates the potential of a robust, low-cost approach to programmable matter using beads and string to achieve complex shapes with novel self-organizing and deformational properties. The method is inspired by the observation that beads forced together along a string will become constrained until they spontaneously rigidify. This behavior is easily observed using any household string and flat-faced beads and recalls the mechanism behind classic crafts such as push puppets. However, specific examples of architectural applications are lacking. We analyze how this phenomenon occurs through static force analyses, physical tests, and simulation, using a rigid body physics engine to validate digital prototypes. We develop a method of designing custom bead geometries able to be produced via generic 3D-printing technology, as well as a computational path-planning toolkit for designing ways of threading beads together. We demonstrate how these custom bead geometries and threading paths influence the acquired structure and its assembly. Finally, we propose a means of scaling up this phenomenon, suggesting potential applications in deployable architecture, mortarless assembly of nonfunicular masonry, and responsive architectural systems.
