Development of transformable anticlastic structures for temporary architecture

The objective of this paper is to develop transformable anticlastic structures based on the geometry of hyperbolic paraboloids (hypars) for temporary architecture. At first, 2DoF (degrees-of-freedom) transformable hypar structure that is capable of shape changes both in plane and on space has been introduced. Then, hypar structures have been connected to each other with respect to the developed design methodology. Starting from joining four hypars together, different types of anticlastic structures have been generated. After studying the morphology and kinematic analyses of the generated structures, a transformable hexagonal joined-hypar structure has been developed as an example of architectural application of such structures. The proposed structure has the ability to change its shape from planar geometry into various doubly-curved geometries. The movement of the structure is provided by means of actuators in its system. By controlling the actuators, the geometry of the structure is adjusted according to the activity and user requirements
