Publication EmbargoA Study on Measuring Complexity in Muqarnas Patterns(2019-04) Alaçam, Sema; GÜZELCİ, ORKAN ZEYNEL; 187152; 152924Throughout history, mathematicians from different cultures and places traced other scholars' work to make a contribution and extend the knowledge of the geometry field. In the Islamic world, artisans combine the theoretical knowledge about geometry and making skills to build more sophisticated and complicated geometric patterns. Today, the underlying principles of geometric patterns are still a research subject of many physicists and mathematicians. Geometric patterns are used both in design and construction phases of muqarnas which is a specialized spatial element in Islamic Architecture. In the scope of this study, after a comprehensive analysis, new muqarnas patterns are generated by using algorithms. Publication Open AccessComputational Interpretations of 2D Muqarnas Projections in 3D Form Finding(2016-11) Alaçam, Sema; GÜZELCİ, ORKAN ZEYNEL; 152924; 187152In the scope of this study, we developed an algorithm to generate new 3D geometry (interpretation) of a given or generated planar projection of a muqarnas in a digital 3D modelling software (Rhinoceros), its visual scripting environment (VSE) Grasshopper and also Python programming language. Different than the traditional methods, asymmetrical form alternatives are examined. In other words, 2D projections of muqarnas were only used as an initial geometrical pattern for generative form finding explorations. This study can be considered as an attempt to explore new relations, rules and vocabulary through algorithmic form finding experiments derived from 2D muqarnas projections. Publication RestrictedDesign Tactics for Enhancing the Adaptability of Primary and Middle Schools to the New Needs of Postpandemic Reuse(Emerald Group Publishing Ltd., 2021) Sen Bayram, Asena Kumsal; Alaçam, Sema; GÜZELCİ, HANDAN; Akkuyu, Elif Işık; Sencan, İnanç; GÜZELCİ, ORKAN ZEYNELPurpose - The aim of this study is to present design tactics (DTs) for supporting the adaptability of existing primary and middle school buildings into the emerging needs of coronavirus disease 2019 (COVID-19). The study introduces a novel algorithmic model for postoccupancy evaluation of the existing school buildings and provides solutions to enhance the adaptability of these buildings. Design/methodology/approach - This study employs the DTs defined by the authors, integration of DTs to the algorithmic model and tests the usability of the proposed model in the selected sample set. The sample set consists of four primary and middle school buildings with different architectural qualities. The degrees of flexibility of the existing sample set are evaluated depending on the outcomes of the implementation. Findings - The degrees of flexibility are achieved as a result of execution of the algorithmic model for each selected school building. Initial results of the case studies show that the flexibility of a school building is highly related to affordances and design decisions of the plan layout which were considered in the initial phases of the design process. Architectural qualities such as open plan and having sufficient voids in the interior and exterior space become prominent factors for ensuring flexibility. Originality/value - Developing a systematic approach to the adaptation problem of primary and middle school buildings to postpandemic reuse is a novel research topic. Apart from this contextual originality, the proposed taxonomy for postpandemic reuse in terms of three levels of adaptation is a new conceptual framework. Moreover, the propos Publication Open AccessDigitizing the Unexplored: Bridging the Concrete Experience and Abstract Geometry Through Physical Experiments(2016-04) Alaçam, Sema; GÜZELCİ, ORKAN ZEYNEL; 152924; 187152Ways of promoting creative approaches in the context of embedding digital design approaches in education are increasingly becoming a popular topic in architecture schools. On one hand, digital design methods, approaches and tools are diversified, while on the other hand, the danger for students losing control over the design process by appears as a new phenomenon. We argue that experiential dimensions of empirical observation conducted with physical experimentation might be helpful for students to comprehend digital topics creatively. With a particular emphasis on engagement of physical experimentation and computational thinking, this study aims to present a pedagogical model which has been applied from 2014 to 2016 within a postgraduate course. The potentials and limitations of the introduced pedagogical model are investigated through students' bottom-up and top-down algorithm development processes and the outcomes of the digital modelling exercises. Publication Open AccessEnhancing Flexibility of 2D Planar Materials By Applying Cut Patterns For Hands On Study Models(2016-11) Alaçam, Sema; Bacınoğlu, Zeynep; GÜZELCİ, ORKAN ZEYNEL; 187152; 152924Active experimentation during intertranslations between digital and physical modelling allow designers to explore new geometrical possibilities. Particularly, while changing the strength of the material, cut operations augment bending performance of the planar surfaces. Keeping in mind the potentiality of bending behavior as a generative tool for computational process, this paper presents the findings of three phased experimentation: implication of cut patterns to 2D planar material, mapping 2D patterns onto 3D surfaces and exploring new 3D free-form surfaces. Publication Metadata onlyReconnoitring computational potentials of the vault-like forms: Thinking aloud on muqarnas tectonics(Sage Publications Ltd, 1 Olivers Yard, 55 City Road, London EC1Y 1Sp, England, 2017-12) Alaçam, Sema; Gürer, Ethem; Bacınoğlu, Saadet Zeynep; GÜZELCİ, ORKAN ZEYNEL; 152924; 187152; 110151This study sheds light on a holistic understanding of muqarnas with its historical, philosophical and conceptual backgrounds on one hand and formal, structural and algorithmic principles on the other hand. The vault-like Islamic architectural element, muqarnas, is generally considered to be a non-structural decorative element. Various compositional approaches have been proposed to reveal the inner logic of these complex geometric elements. Each of these approaches uses different techniques such as measuring, unit-based decoding or three-dimensional interpretation of two-dimensional patterns. However, the reflections of the inner logic onto different contexts, such as the usage of different initial geometries, materials or performative concerns, were neglected. In this study, we offer a new schema to approach the performative aspects of muqarnas tectonics. This schema contains new sets of elements, properties and relations deriving partly from previous approaches and partly from the technique of folding. Thus, this study first reviews the previous approaches to analyse the geometric and constructional principles of muqarnas. Second, it explains the proposed scheme through a series of algorithmic form-finding experiments. In these experiments, we question whether 'fold', as one of the performative techniques of making three-dimensional forms, contributes to the analysis of muqarnas in both a conceptual and computational sense. We argue that encoding vault-like systems via geometric and algorithmic relations based on the logic of the 'fold' provides informative and intuitive feedback for form-finding, specifically in the earlier phases of design. While focusing on the performative potential of a specific fold operation, we introduced the concept of bifurcation to describe the generative characteristics of folding technique and the way of subdividing the form with respect to redistribution of the forces. Thus, in this decoding process, the bifurcated fold explains not only to demystify the formal logic of muqarnas but also to generate new forms without losing contextual conditions. Publication EmbargoTree-Step Experimentation on Embedding Curvature to Rigid Planar materials Through Cut Patterns(2017-11) Alaçam, Sema; Bacınoğlu, Zeynep; GÜZELCİ, ORKAN ZEYNEL; 187152; 152924This study presents the outcomes and findings of a three-step experimentation to integrate analog and digital design and modeling techniques, with a particular focus on augmenting the affordance of bending behavior and curvilinearity of rigid planar surface materials. In the scope of the experimentation process, cardboard was used as a material, cutting and bending actions were utilized as techniques and laser cut and visual scripting environment were involved as tools. The potentials of subtractive material techniques such as cut, bend, kerf operations are examined. The experimentation covers hands-on pattern generation, embedment of cut patterns to 2D planar material, re-mapping 2D patterns onto 3D surfaces based on the insights gained in the previous phase and exploration of new 3D free-form surfaces both in physical and digital environments. The three-step experimentation model presented has potentials to contribute to the pedagogical studies focusing on explorative and creative approaches for integrative design formation and fabrication processes.
