    Incorporating United Nations 2030 Sustainable Future Agenda into the Architectural Studio: A Graduation Studio Case
    (John Wiley and Sons Inc, 2022) Özlem Erdoǧdu Erkarslan; Yenal Akgün; Erkarslan, Özlem Erdoğdu; Akgün, Yenal
    United Nations (UN) released the 2030 Agenda for Sustainable Development in 2015. This agenda has received attention from various disciplines and sectors globally, partnerships from private and public sectors were formed to play a role in this challenging ambitious plan. However architectural education and professional organisations in Turkey have not been strongly engaged with the agenda in particular. To meet this gap and create synergy this paper aims at presenting pedagogical paths followed in a graduation studio integrating the studio outcomes with UN 2030 Sustainable Development Goals (SDGs) which have not been widely covered either in nationwide architectural education or professional policies. In addition the paper focuses on how the SDG action plan is echoed in higher education as well as in the discipline of architecture in Turkey. The paper is a case study in architectural education of which the motivation is to create awareness about UN SDGs among the students, to give insights and demonstrate a realistic design policy to achieve development targets. The pedagogical path presented here is original and aims to fulfill an interlude in the literature which is still emerging. The case presentation includes the process and the results with a sufficient number of student projects as outcomes of the studio. © 2022 Elsevier B.V. All rights reserved.

    Structural comparison of scissor-hinge linkages
    (CRC PRESS-BALKEMA, 2019) F. Maden; Y. Akgun; K. Yuceturk; E. Aktas; M. Y. Uncu; C. Mitropoulou; Mitropoulou, C.; Akgün, Y.; Aktaş, E.; Uncu, M.Y.; Maden, F.; Yücetürk, K.; PJS Cruz
    Deployable structures can deploy from a compact to an expanded configuration by changing their sizes. The behaviors of these structures depend on some parameters such as geometric shape member sizes and kinematic properties. To provide the deployment not only the arrangements of structural members but also some restrictions must be considered. Moreover contiguous members of the structures must let the large rotations to provide the transformation between different geometric forms from fully folded to fully deployed configurations. These requirements have an important impact on the fundamental properties of the structures related with structural performance such as stiffness and strength. In this paper stiffness of different scissor-hinge linkages are analyzed and compared. These linkages cover the same span with almost the same geometry and have the unit elements with same size and same weight. However the geometry of unit elements is different from each other. The paper investigates the effect of this difference on the stiffness of whole system.

    Ahşap malzemede kerf kesim tekniği üzerine bir değerlendirme
    (DergiPark, 2024) Yenal Akgün; Gökçe Kırkpınar; Matthieu Joseph Pedergnana; Pedergnana, Matthieu Joseph; Kırkpınar, Gökçe; Akgün, Yenal
    Ahşap geleneksel endüstriyel yapı malzemelerine kıyasla sağladığı hafiflik ve çevresel avantajlar ile mimarlar iç mimarlar ve mobilya tasarımcıları için her zaman ilham kaynağı olmuştur. Ahşap uygun kalınlıklarda doğru kesim ve üretim teknikleri uygulandığında esnek bir yapıya dönüştürülebilmektedir. Bu esnekliği kazandırma yöntemlerinden birisi de kerf kesim tekniğidir. Kerf kesim tekniği bir panel üzerinde belirli bir desen veya şekil oluşturmak için kesimler yaparak sert bir malzemeyi esnek hale getirmeye dayanır. Bu sayede karmaşık fabrikasyon yöntemlerine ve ileri teknoloji malzemelere ihtiyaç duymadan esnek ve şekil değiştirme özelliğine sahip mimari elemanlar ve mobilya ürünleri tasarlanabilir. Bu çalışmada kerf kesim tekniğinin ahşap ürünlerdeki kullanım alanları incelenerek kesim teknolojileri üretim teknikleri kesim tipleri ve desen türleri üzerinden bir sınıflandırma yapılmaktadır. Kerf kesim tekniğinin ahşap işleri alanında önemini ve son yıllarda artan ilgiyi vurgulayan bu çalışma tasarımcılar ve üreticiler için yenilikçi bir üretim yöntemi sunmaktadır. Bu teknik esnek ve estetik açıdan özgün tasarımların geliştirilmesine katkıda bulunarak ahşap ürünlerin kullanım alanlarını genişletme potansiyeline sahiptir.

    Geometric Design of Planar Scissor Linkages with Hybrid Loop Assemblies
    (ASCE-AMER SOC CIVIL ENGINEERS, 2022) Nazli Hilal Sarisayin; Yenal Akgun; Feray Maden; Ozgur Kilit; Kilit, Ozgur; Sarisayin, Nazli Hilal; Sarlsayln, Nazll Hilal; Akgun, Yenal; Maden, Feray
    Due to their expansion capabilities and the simplicity of their design scissor linkages have been used in both architecture and engineering for various applications such as expandable roofs and shelters movable bridges furniture and as parts of mechanisms. The two main design methods used for scissor linkages are the unit-based method and the loop-based method. While the unit-based method is based on serial multiplication of the scissor units the loop-based method is based on aligning predefined loop types onto the desired curve. When the input parameter is the desired curvature for the finally deployed configuration of the linkage the loop-based method is easier and more convenient for defining the scissor units to create the whole linkage geometry. Most of the existing studies on the loop-based method deal with identical or arbitrary loops. Hybrid loop assemblies have not yet been studied although they may offer different geometric alternatives. This work aimed to fill this gap in the literature and present a geometric design approach for scissor linkages composed of hybrid loop assemblies using frieze patterns. First the basic terminology such as loop types loop assemblies and frieze patterns is introduced. Then we discuss scissor linkages using hybrid loops generated using a predefined rectilinear geometry in which frieze groups are used to provide diverse variations. The kinematic definitions of the represented linkages are then explained. To reveal the potential applications of the scissor linkages composed of hybrid loops a case study was conducted in which the proposed linkages were used as a canopy structure. After discussing the potential for using hybrid loops and their deployment we present the concluding remarks and make suggestions for future research. (C) 2022 American Society of Civil Engineers.

    Weight and Material Optimization of Scissor-hinge Linkages According to Given Span Length
    (Elsevier B.V., 2020) Yenal Akgün; Feray Maden; Erinç Yildirim; Yildirim, Erinç; Akgün, Yenal; Maden, Feray; N.D. Lagaros , K.M. Abdalla , G.C. Marano , M.C. Phocas , R. Al Rousan
    Scissor-hinge linkages are one type of deployable structures which are mostly used in architectural and engineering applications due to their transformation capabilities and the advantages of ease of erection and dismantling. For hundreds of years these linkages have been used in wide range of applications such as deployable roof structures bridges shells pavilions emergency shelters furniture design and satellite equipment. Scissor-hinge linkages have different primary units depending on the geometry of the bars and the location of the pivot point which are called as polar translational and angulated. Geometry and dimensions of these primary elements directly affect the geometry and the weight of the whole structure. This study aims to investigate the relationship between the span length geometry of the primary units cross section of the bars and the material of the scissor-hinge linkages by means of genetic algorithms. In detail a structural and geometric optimization is made in order to obtain the lightest geometric configuration for the given span lengths while keeping the structural strength and stability by altering typology dimensions number of the primary units and material parameters. To achieve that a multi-objective genetic algorithm based optimization approach is utilized. Generative model is created in Grasshopper® parametric design software. The structural performances of the generated solutions are evaluated with the help of Karamba3D that is a parametric structural tool for Grasshopper. Optimization of the problem is performed via multi objective genetic optimization plug-in named Octopus. © 2020 Elsevier B.V. All rights reserved.

    (ECAADE-EDUCATION & RESEARCH COMPUTER AIDED ARCHITECTURAL DESIGN EUROPE, 2022) Canberk Kavuncuoglu; Yenal Akgun; Ozan Onder Ozener; Kavuncuoglu, Canberk; Akgun, Yenal; Ozener, Ozan Onder; B Pak; G Wurzer; R Stouffs
    This paper presents a case study focusing on BIM integration to kinetic structure design based on an extended kinetic BIM (KBIM) ontology through a Bricard linkage canopy system. With the parametric abstraction of structural system components and kinematic behaviors the design process was carried out in a BIM environment using KBIM models and objects. The study results show the effectiveness of the proposed KBIM framework for the synthesis and assessment of design alternatives according to total system performance architectonic composition and environmental responsiveness.

    A critical review on classification and terminology of scissor structures
    (Int. Association for Shell and Spatial Structures, 2019) Feray Maden; Yenal Akgün; Gökhan Kiper; Şebnem Gür; Müjde Yar; Koray Korkmaz; Korkmaz, Koray; Yar, MÜJde; Kiper, GÖKhan; Akgun, Yenal; Maden, Feray; Gur, Sebnem
    When the existing literature on the research of scissor structures is thoroughly investigated it is seen that different researchers use different terminologies and classifications especially for the definition of the primary units and the motion type. Some of the studies define the whole geometry based on the geometric properties of the primary scissor units and the unit lines while some other studies define it according to the loops. All these studies use different names for similar elements. This article aims to review the literature on the classification and terminology of scissor structures and represent the state of art on the studies. Tables are represented showing all approaches in the literature. In addition the article criticizes the missing points of each terminology and definition and proposes some new terminology. In order to arrive at this aim different definitions of the primary scissor units and motion types used in key studies in the literature are investigated thoroughly. With several examples it is demonstrated that naming the scissor units according to the resulting motion type might be misleading and it is better to specify the motion type for the whole structure. A classification for transformation of planar curves is presented. © 2019 Elsevier B.V. All rights reserved.

    A novel planar scissor structure transforming between concave and convex configurations
    (Wit Press, 2017) Müjde Yar; Koray Korkmaz; Gökhan Kiper; Feray Maden; Yenal Akgün; Engin Aktaş; Korkmaz, K.; Yar, M.; Kiper, G.; Akgün, Y.; Aktaş, E.; Maden, F.
    In this paper a novel two-dimensional scissor structure that transforms between concave and convex configurations is presented. The structure is designed by a method of assembling kite or anti-kite loops in the flat configuration. Angulated units are generated from the assembled loops. Finally a new angulated scissor unit is introduced in order to design the novel scissor structure. © 2023 Elsevier B.V. All rights reserved.
