    Design of Rollable Reciprocal Frame Network
    (int Assoc Shell & Spatial Structures-iass, 2024) Ozen, Gulcin; Korkmaz, Koray; Kiper, Gokhan
    In the literature, reciprocal frames have been studied mostly for static structures. Studies on kinetic reciprocal frames are very limited. This study investigates two degrees-of-freedom reciprocal frame fans, and a novel deployable reciprocal frame network is obtained. While the network has a single degree-of-freedom in the crosssection, it has multi degrees-of-freedom in the longitudinal section. The network can be rolled to obtain a compact form and takes the form of a vault form when deployed. The way the nexors come together in the designed network is similar to the Da Vinci Bridge. The only difference is that cylindrical and prismatic joints are used in the intersection points to make the designed network deployable.

    A Novel Transformable Structural Mechanism for Doubly Ruled Hypar Surfaces
    (The American Society of Mechanical Engineers(ASME), 2015) Maden, Feray; Aktaş, Engin; Korkmaz, Koray
    A novel structural mechanism (SM) that is capable of transforming itself into various hyperbolic paraboloid (hypar) geometries is introduced in this paper. Composed of straight bars and novel joint types, the SM is designed based on the ruled surface generation method. Thus, the paper first investigates the geometrical properties and morphology of the hypar surface. Second, it constructs the SM and discusses its transformation capability with respect to its kinematic properties. Then, it presents a parametric model not only to analyze the geometry and possible configurations of the SM but also to prepare a model for the structural analysis. Finally, a transformable shelter structure is proposed as an architectural application of the SM and its feasibility is tested based on the structural analysis conducted in different configurations of the structure. According to the results of the structural analysis, the strength, and the stiffness of the structure are discussed in detail.
