    Kinematic Design and Analysis of Deployable Vault and Pseudo-Dome Structures Based on Origami Techniques
    (Izmir Institute of Technology, 2017) Karaveli Kartal, Andree Sonad; Korkmaz, Koray; Korkmaz, Koray; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of Technology
    In recent years a need for more adaptable and flexible structures have been observed due to the changing spatial and functional needs. One of the solutions for an adaptable space in architecture is deployable structures. These kinds of structures provide flexible solutions to the functional and spatial necessities of an environment. There are different kinds of deployable structures such as bar and foldable plate structures, membrane, inflatable, cable/strut etc. This study presents a method of designing a pseudo-dome flat-foldable and deployable plate structure (rigid origami) based on origami patterns that have a polar rotation deployment axis. To achieve this objective, first a method of designing flat-foldable and linearly deployed barrel vault structures have been created by analyzing their geometrical properties. This analysis along with a workspace analysis provided knowledge on the geometrical relations between the cross-sections and deployment parameters. These relations allowed the design of a flat-foldable rigid origami structure based on the geometry of the cross-section using a pattern-generator. The method of using a pattern-generator to create an origami pattern has been modified to achieve a polar rotated deployable pseudo-dome structure. The design method allows the designer to calculate all the relevant parameters to create an origami structure by modifying three parameters for barrel vault foldable structures and two parameters for pseudo-dome structures. The created origami pattern is then transformed to a foldable deployable plate structure with the intended design requirements. The design processes for both design methods have been explained with case studies.

    An Approach for Developing Sensitive Design Parameter Guidelines To Reduce the Energy Requirements of Low-Rise Apartment Buildings
    (Elsevier Ltd., 2012) Yıldız, Yusuf; Korkmaz, Koray; Durmuş Arsan, Zeynep; Durmuş Arsan, Zeynep; Korkmaz, Koray; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of Technology
    High levels of energy consumption in residential buildings and global warming are important issues. Thus the energy performance of buildings should be improved in the early stages of design. This article describes an approach for developing guidelines on sensitive and robust design parameters for the present, the 2020s, the 2050s and the 2080s. Such guidelines can help architects to design low-rise apartment buildings that require less energy for various purposes, such as heating or cooling. The article consists of a general literature review, interviews with architects, the generation of case-specific information and a mock-up presentation and a meeting with professionals. An example guideline that aims to reduce annual cooling energy loads under global warming in low-rise apartment buildings located in hot-humid climates is presented to demonstrate how the proposed approach can be applied. For this guideline, case-specific information was generated, and a global sensitivity analysis based on Monte Carlo Analysis and the Latin Hypercube Sampling technique was performed. The results show that the suggested approach is feasible and could be used to provide helpful information to architects during the design of low-rise apartment buildings with high energy performance. The most sensitive design parameters that affect annual cooling energy loads in low-rise apartment buildings were natural ventilation, window area, and the solar heat-gain coefficient (SHGC) of the glazing. The results are relevant for the present, the 2020s, the 2050s and the 2080s.

    Design of a Reconfigurable Deployable Structure for Post Disaster Housing
    (Izmir Institute of Technology, 2014) Ataer, Fulya; Korkmaz, Koray; Kiper, Gökhan; Korkmaz, Koray; Kiper, Gökhan; 02.02. Department of Architecture; 03.10. Department of Mechanical Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology; 02. Faculty of Architecture
    In this thesis, the possibility of constructing reconfigurable deployable structure composed of planar linkage units has been explored. The first part of the thesis is devoted to literature survey on housing recovery. When the current researches on post disaster housing are investigated, it is observed that most of post disaster housing or temporary buildings in the literature are predefined portable, demountable or relocatable buildings. Deployable buildings serve for a single function. A study into the existence of alternative forms of a reconfigurable deployable structure has been done. The conditions for the alternative forms to be a multi-functional building have been derived. Reconfigurable deployable structure presented here is a single degrees-of-freedom (DoF) multi-loop linkage which has more than two configurations. The alternative forms that a linkage is constructed with the same links and connections are called configurations or assembly modes of the linkage. During its motion, the linkage may pass from one assembly mode to another, which is called reconfiguration or assembly mode change. Design and position analysis of the linkage mechanism have been implemented in Microsoft Excel® environment. The link lengths can be varied in this environment and the motion of the structure can be simulated by changing input joint parameters. Four different case studies have been designed in Microsoft Excel®. A reconfigurable deployable structure can be used as a multi-functional shelter or canopy which can take many forms in a few minutes for urgent needs after disasters, military purpose or public needs. Its deployed and retracted (or compact) geometries are explored. As a case study the dimensions of links are presented. Installation process for different functions is explained. The full concept for the structure, from outer covering material to foundation is then detailed. Finally, a sample material cost analysis is performed to determine if the product is financially feasible.

    Bio-Inspired Design of a Kinetic Node for Adaptable Structures
    (Izmir Institute of Technology, 2011) Acar, Melodi Simay; Korkmaz, Koray; Korkmaz, Koray; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of Technology
    The architectural design should no longer consider just in terms of today's demands, but also the life cycle and the further requirements of the built environment. The design process should consider the adaptation to the changing conditions which can be in terms of the building usage, environmental factors or even in the changes ofsociological demands. Rapid change in activities of modern society and building technologies, has led to the need for adaptable spaces. Those spaces can be obtained by the adaptable structures which have potential for using our resources in efficient way and also for responding to the era's needs. This can be achieved with kinetic structural systems and learning adaptable structures from nature.Nature has always inspired humanity by solving the basic needs with minimum material and sustainable solutions. Observation of nature enables architects and engineers familiar with highly developed structures and lead to the creation of new forms. The designs that are produced by learning from nature lead to practical engineering solutions in terms of sustainability. The aim of this research is to propose a joint; kinetic node with multidisciplinary approach. This kinetic node is designed by inspiring from the minimum energy shape configurations and the structural orders in natural structures especially the cell membrane and analyzing the joining details of space truss structural systems and the geometric principles of Bricard linkage mechanism. This new kinetic node gives capability to construct variable static and dynamic structural systems while constructing in different structural orders.
