Book Part Citation - Scopus: 1Design of Adaptive Structures by Kinematic Synthesis of Mechanisms(CRC Press, 2013) Akgün,Y.; Maden,F.; Korkmaz,K.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. © 2013 by Taylor & Francis Group, LLC.Book Part Design of Reconfigurable Doubly-Curved Canopy Structure(CRC Press, 2013) Maden,F.; Korkmaz,K.; Akgün,Y.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. © 2013 by Taylor & Francis Group, LLC.Article Citation - Scopus: 13Generation of a New Type of Architectural Umbrella(Multi-Science Publishing Co. Ltd, 2005) Korkmaz,K.The essence of this paper is the proposal of an innovative type of architectural umbrella. The new umbrella consists of a new type of symmetric spatial one-degree of freedom platform mechanism, a flexible covering with ribs and a hollow cylindrical mast with rotational movement. The most distinctive features of the umbrella are the expansion process and the way input is applied. As for the conventional foldable umbrellas, the joints should permit certain controlled movements, which in their turn would cause the process of the open and closed configurations of the umbrella. Graphical synthesis method is used to design and develop the mechanism.
