Deployable architectural umbrellas are widely used for providing shade in large open spaces, combining functionality with aesthetic appeal. Most existing designs rely on structural mechanisms as the primary framework, with membranes or textiles serving as the covering material. Although this approach reduces structural weight and simplifies deploym...

Adaptive façades predominantly employ rigid body mechanics to initiate motion. The manufacture of such systems is costly, susceptible to malfunction, and challenging to maintain, rendering them both economically and environmentally unviable for operational purposes. However, compliant mechanisms are mechanical systems that achieve motion or force t...

Responsive architectural structures measure actual environmental conditions using sensors and allow buildings to adapt their form, shape, color, or character responsively using actuators. However, the use of multiple actuators and relying on rigid body hinges can decrease the applicability of these responsive architectural structures. The explorati...

Deployable structures can deploy from a compact to an expanded configuration by changing their sizes. The behaviors of these structures depend on some parameters such as geometric shape, member sizes and kinematic properties. To provide the deployment, not only the arrangements of structural members but also some restrictions must be considered. Mo...

Summary When the current research on transformable structures is investigate, it can be seen that most examples do not offer truly flexible alternatives. Although certain parts of these structures do move, rotate or slide, the general shape of the roof never changes. These examples therefore do not constitute real form flexibility, despite the need...
