Latest studies in cultivated material design depict that the vegetative part of a fungus consisting of a network of rhizomatic and fibrous white filaments, the mycelium, could be an alternative for composites which composed of a ductile matrix and high-strength reinforcement. The goal of the present work is to discuss the potential of the usage of mycelium as a binding agent in free form geometry since mycelium acts as a natural selfassembling glue while following its metabolic cycle. Hence, shaping and re-shaping capabilities of mycelium-bond materials using fabric formwork is discussed. This study is the result of a series of experiments about mycelium-bond material that aims to investigate its re-shaping potentials by using an adjustable mold. We aim to make a comparison between initial and end shapes of cast material by implementing digital and analogue tools based on mycelium-based fabric formwork experiment. The formwork enables the designer to manipulate the boundary conditions of the fabric mold. The physical experiment setup consists of different initial geometry alternatives and the deformation is observed and measured numerically by time-based recording on top and section views. With the help of digital tools, experiments were documented as a process of formation. To analyze the mycelium-bond material, which refers to a material which can take form by growing mycelium under certain conditions, shaped by fabric formwork two different approaches were followed. The first approach is to keep the initial geometry defined by digital design tools of the fabric formwork fixed and to determine the resulting analogue shape from elastic deformation. The second approach is to keep the final analogue geometry fixed then to find the closest fit solution possible within a fabric formwork.

Architecture is inherently intertwined with movement and body. One of the most intense observations of the movement is undoubtedly dance performance. Architecture and dance share the same language in terms of shape and form; both disciplines transform solid bodies and space to identify themselves. In recent years, involving computers to design process leads to digital analysis of movements. Movement data is available with movement analysis in computational environment. These data can be used as design components for different disciplines. In this article, it is emphasized that dance data can be used to create dynamic spaces and architectural forms in interaction with body movements. Within this scope, the relation among the time, space and movement is examined. Motion capture and motion transformation techniques are studied. In this content, it has been worked with a group dancers as subjects and their movements were transferred to computational environment using Kinect, Grasshopper and Quokka interfaces. Dancers movements were scanned and the motion data for each joint were stored for the analysis process. Thanks to the computational environment, the models based on the movement data were produced and the movement traces in the space were concretized and analyzed. The interaction of the created forms with the dancer and the reflection of the of body movement dynamics on the form produced were intensified. At the end of the study, the productive results of using dance movement data in search of dynamic and interactive forms instead of the usual solid, stationary forms of architecture are shown.

Computational approaches and methods has bringed new era in relationsihp between geometry and architecture. Within the scope of this study, the reflections of developments in Computational Geometry on the design will be deduced and a design developed with Triply Periodic Minimal Surfaces will be presented. In contrast to traditional physical research methods, the innovations of Computational Design Methods in Minimal Surfaces and also in design will be examined with the applications of this innovations in architectural examples and application areas. The main aim of the study is to create an Architectural design composition which consists of interpreted Triply Periodic Minimal Surfaces, which are geometric examples derived with Computational Thinking. For a conceptual framework, a polygonal area which has divided edges according to parameters (eg number of enters and exits) will be subdivided into quadrilaterals and then Triply Periodic Minimal Surfaces modules will be derived according to these quadrilaterals.

This paper was produced from the master thesis titled ‘’Computing and Knitting: Experiments on Tailoring Concrete and Knitted Textile for Shell Structures‘’ that published on December 2017 in ITU Architectural Design Computing Graduate Programme. The thesis proposes an integrated design and production approach to seek future construction scenarios for the complex concrete thin shell structures by utilising material behaviour and computational tools. The investigations focus on the findings and the outcomes of the composite usage of concrete (as a compressive material) and knitted textile (as a tensile material). In the scope of this study three phased experiments were conducted, which comprised of; (i) material experiments, (ii) form finding and structural analysis, (iii) production of physical prototypes. In order to achieve the feasible form alternatives the integration of material feedbacks from physical models and the structural feedbacks from digital model was provided. In order to get a deep understanding about the material limitations and to determine optimum cement mixture to obtain maximum mechanic behaviour from the composed material, microstructure analysis were completed in material scale.Motivated by the feasibility problems of complex concrete shells, the potentiality of initially delicate and flexible materials are explored to generate structurally efficient lightweight concrete shells in order to eliminate the need for formwork, minimize the production cost and time by promising less labor-intensive, more sustainable and wastefree structures.

Creation of form in architectural practice has been historically a topdown process. However, the creation of form doesn’t have to follow the conventional architectural process. There are also emergence-based approaches that evolve through reactions to the environmental factors, and some of these structures would fall under the vernacular category. This study focuses on how perceptible aspects of architectural forms can be used as a method to discern the actual quantitative characteristics through certain visual, simplified versions of forms, described in this article as “node patterns.”. Patterns usually invoke the idea of two dimensional textures or sequences, but they can also be utilized to categorize architectural forms in certain archetypes. This way of describing complex architectural forms might offer certain advantages in finding out the qualitative properties of architectural forms, such as permanence, ease of construction, function, etc. This study puts forward the concept of “node” as the most primitive building block of a pattern. A node is defined as the most simplistic, discrete unit of a pattern, that can be easily identified by a user who’s not technically educated as a designer or an architect. Patterns, which define certain architectural archetypes, are discussed in two different dichotomies: monolithic vs discrete, and regular vs random. These four qualities are then matched with three dimensional dichotomies like horizontal vs vertical, linear vs massive. Several real-world examples are discussed and the inherent qualities of the patterns are presented.

Recent years have seen the use of diagrid structural systems becoming widespread in architecture. Diagrids are advantageous mostly for cutting down on the number of structural elements used. However, the use of diagrid structural systems is still not common in free-form highrise designs. Most high-rise designs are symmetrical and orthogonal structures whereas free-form as a type of building geometry form implies asymmetric configurations, without a fixed order or a central rotation axis. Among the difficulties observed in free-form high-rise designs is efficiency in the analysis and synthesis of structural solutions and in the physical realization of the structural elements. Overcoming these difficulties requires computational support. However, most of the existing software up to the task are protected by copyright and expensive, hence inaccessible to many small firms and individual designers. Addressing the problems of affordability and accessibility, the study presents a computational support system for preliminary design proposals of diagrid structures in free-form high-rise designs. This support takes place in an algorithmic design interface, and the biggest advantage is that designers can integrate the design and analysis phases in a single interface. The model has three main phases. These phases are the creation of a free-form high-rise geometry, structural analysis of this geometry when modelled as a diagrid structural system, and the numbering and sequencing of the most important structural element that is node connector so that it is suitable for the prefabrication. Based on the structural assessment of the model, the study also discusses the alternatives of diagrid structural systems to see whether the potential structural element may be added to the diagrid structural system.
