A classification matrix proposal for digital fabrication techniques in architecture
(2018-11) Öztürk, Selen
This thesis investigates the relationship between digital fabrication techniques and the design constraints, such as function and materials, which are determined during architectural design processes by architects. This relationship is formulated through a matrix. Digital fabrication techniques are generally discussed upon and decided at the last step of a design process. This study roots from the idea that knowing which technique to use for fabrication affects the design process. In that sense, ‘according to which constraints which technique suits the design intention best’ should aid the designers. To propose a classification matrix two steps are practiced: first, as digital fabrication is a newly developing area, there are confusions, shifts, and overlaps of terminology among fabrication techniques; thus a simplification and classification in the terminology is needed. Such a classification is carried out in this thesis through recurrence tables based on a literature survey, the output of which constitutes the main column of the matrix. Secondly, a set of design constraints are determined by analyzing built projects, which are realized using specific digital fabrication techniques. This set of constraints establishes the columns of the matrix. The classification matrix aims to contribute both to educational and practical sides of architecture, proposing digital fabrication techniques to designers according to specific design constraints.

Cognitive Comparison of design methods in the conceptual phase
(Sage Publications Ltd., 2023-07-12) Gürel, Adel; Şenyapılı Ozcan, Burcu
The initial phases of design, known as the conceptual design phases, are often associated with hand sketching, while parametric tools are reserved for the later, more developed stages of design. This paper examines the potentials of using parametric tools in the early design phases in comparison to widely utilized hand sketching. It is intended to find out the impacts of using parametric tools on the cognitive behaviors and the satisfaction of self-assessment levels of the designers. An experimental study was conducted with a group of graduate architecture students using Grasshopper, the findings of which are analyzed through a content-oriented coding scheme, together with protocol analyses. Significant differences are found between cognitive behaviors of the participants in using hand sketching and Grasshopper. The findings show that all of the participants consider Grasshopper as a useful conceptual design tool that may be utilized in early design phases, in contrast to its wide popularity in the late stages of design.

Homogenization-based computational design and two-scale performance optimization of electroactive structures
(2024-09) Dedeoğlu, Berkan
Macroscopic materials and structures with enhanced characteristics have been extensively studied in the context of solid mechanics. The advantages of mi- crostructured materials with active constituents have been reported in the lit- erature. In view of tunable microstructures, further intriguing traits of such materials can be achieved through imposing external stimuli. The ultimate goal of the present study is to establish a homogenization-based computational design framework to actively control the time-varying macroscopic stress response and behavior of structures with piezoelectric constituents. This is accomplished by temporally adapting the macroscopic electric field enforced on a microstructure and controlling the time-variation of the macroscopic electric potential imposed on a macroscopic solid. This periodic microstructure is optimized in a non- restrictive design space that embodies not only the topology, but also anisotropic material orientation and the unit cell geometry. In order to enrich the optimiza- tion space to capture the intriguing time-varying mechanical aspects, additional optimization variables, namely performance variables, are developed. Extensive numerical investigations are conducted to test the limits of this framework based on the discreteness of the microstructure and the accurateness of attaining the targeted mechanical behavior. The overall computational work is implemented through a parallel C++-based in-house FE program.

Pluralist production of urban form: towards a parametric development control for unity in diversity
(Routledge, 2022-04-04) Çalışkan, O.; Barut, Yavuz Baver
The contemporary city is (re)produced in fragments through numerous typological variations. However, the current practice of spatial planning has yet to suggest effective control mechanisms to steer the piecemeal (trans)formation of cities. This paper argues for parametric modelling as a method of guiding fragmentary developments towards the pluralist production of coherent urban fabrics. Following the parametric definition of the basic morphological codes, the paper discusses the computational capacity of parametric modelling to simulate multiple variations in local fabrics and their consecutive integration within a larger context. The proposed model is tested in the context of Istanbul, Turkey.
