    Design of Adaptive Structures by Kinematic Synthesis of Mechanisms
    (CRC Press, 2013) Akgün, Yenal; Maden, Feray; Korkmaz, Koray
    Parallel to the development of material science and computer technologies, adaptive structures and smart building components have become the demand of contemporary architecture. However, in order to design adaptive systems, basic knowledge on kinematic synthesis is needed. This paper introduces the fundamental principles of the kinematic synthesis of mechanisms and expresses the potential structural uses of common mechanisms. For this purpose, main concepts of the mechanisms are introduced and types of kinematic synthesis are explored by the help of innovative examples. In this context, firstly, type synthesis methods are explained. Second step covers the path generation rules, and the final step includes the design of multi-loop and chain mechanisms. During the explanation of the aforementioned principles, innovative adaptive structures which are designed by the authors are introduced as well. These structures are all derived from common planar and spatial mechanisms such as four-bar linkages, Watt mechanisms, scissor systems, Bennett linkages and different multi-loop mechanisms.

    Design of Reconfigurable Doubly-Curved Canopy Structure
    (CRC Press, 2013) Maden, Feray; Korkmaz, Koray; Akgün, Yenal
    In this paper, a new reconfigurable doubly-curved structure has been developed for a canopy roof. The proposed structure can transform itself to various configurations according to the activity and user requirements. It not only changes its shape from a planar geometry to doubly-curved geometries by means of actuators, but also becomes stable and carries loads. The main differences between proposed structure and similar deployable bar structures are that the proposed structure is more flexible with 2DoF and it requires less number of bars and joints. To obtain the doubly-curved geometry, a novel method has been introduced. After discussing the kinematic behavior of the system, a set of structural analyses are performed in three different geometric configurations of the proposed structure.

    Evaluation of Structural Irregularities Based on Architectural Design Considerations in Turkey
    (Emerald Group Publishing Ltd., 2011) İnan, Tuğba; Korkmaz, Koray
    Purpose: The purpose of this research is to show significant points which can be used in the architectural design process by investigating the basic principles of earthquake resistant design (ERD) in a deductive format and to contribute to the architectural perception in ERD. Design/methodology/approach: First, the structural irregularity types are examined depending on the rules defined in the Turkish Earthquake Code, 2007 (TEC). Then, architectural design failures related to earthquake resistance of buildings under earthquake loading are visualized and solution suggestions in literature are described in detail by supported drawings. Findings: The problems causing structural irregularities are investigated deeply with given solutions in literature. It is obtained that the significant factors affecting the earthquake performance of structures are: architectural form, structural configuration, slenderness ratio, the location and rate of floor openings, projection rates and symmetry, rigidity and strength differences between floors, short columns, pounding effect. Social implications - The practical design decision rules can contribute to the phenomena of earthquake resistant architectural design and can encourage adoption of these rules in building industry. Originality/value: This study aims to gain an understanding of the problems in projects in terms of structural irregularities, and then manage to solve the problems using problem-oriented approaches. The suggested solutions can be adopted and applied to future projects for designing earthquake resistant buildings.

    Kinematic Design of a Reconfigurable Deployable Canopy
    (Springer Verlag, 2014) Kiper, Gökhan; Gürcü, Fulya; Korkmaz, Koray; Söylemez, Eres
    A reconfigurable and deployable mechanism is proposed for a canopy which can also be used as a tent or a semi-open structure. The proposed single degree-of-freedom mechanism has four as-sembly modes. The conditions for deployment and reconfiguration of the mechanism are derived. These conditions impose three equality and two inequality constraints on the 11 design parameters of the mechanism. A virtual model of the mechanism is constructed in Excel for design and simulation purposes. A computational case study is presented.
