“…T. Van Mele, combined scissor structures with membrane structures to design covering systems [7]. L. Alegria Mira developed methods for a structural assessment and optimization of scissor grids in conceptual design stages [5]. She developed the concept of the Universal Scissor Component, which can be reconfigured and reused to generate a wide variety of scissor grids [53].…”

“…Finite element models can be used to do a linear analysis of scissor structures in the deployed state subjected to service loads (e.g. wind, snow) [5,54]. A nonlinear analysis of bistable or incompatible scissor structures is required during deployment, subjected to large displacements and geometric incompatibilities [32].…”

“…The beams of the structure are made of aluminium with a Young's modulus of 70 GPa, a poisson's ratio of 0.35, a density of 2700 kg/m³ and a yield strength of 160 MPa. Hollow rectangular aluminium beam cross-sections of 25x50x5 mm were chosen in the design procedure, which corresponds to realistic beam cross-sections for scissor structures [5,17,52]. The mass of the structure is 360.5 kg.…”

“…Applications of deployable structures within the field of architecture and civil engineering include mobile or temporary structures for disaster relief, for construction and maintenance sites, for military operations or for recreational purposes. Examples can be found for bridges [3], towers [4] and shelters [5]. Alternatively, they form transformable extensions to static constructions, such as retractable roof structures [6] for halls or sports stadiums [7] or adaptable façades [8].…”

Shape‐morphing structures capable of significantly altering shape and volume play a crucial role in diverse applications, ranging from soft robotics to minimally invasive surgery, deployable structures, and space exploration. This article presents an approach to achieve simple and controllable morphing onto multiple stable complex 3D surfaces—a long sought after goal in the field. The method is based on interconnected multistable straw‐like deformable tubes, constrained by rigid links that can be assembled and connected in many different ways. By leveraging the director‐field theory, the links and their assembly process are modeled and designed to reach a variety of desired final operational shapes from a single base‐structure. The use of viscous‐fluid actuation enables precise control and predictable shape‐morphing while facilitating a wide range of configurations through inflation and deflation sequences, all with a single input.

Downhill skis are composite materials with very high performances. Very often after few years of use, they are changed due to new fashions or ski techniques. This means a lot of waste which still has the potential for very high structural performances. Thus, the idea to upcycle these materials thanks to a cooperation with the University of Grenoble in the joint activities of their laboratory and Velux Lab. Several tests and dome structures were realized in order to show the potential of these materials. Then a yurt was designed, tested, and pre-built at the Politecnico di Milano before shipping it to Africa, through the equatorial forest in Guinea-Bissau, as a first shelter-base camp in a desolated land where a mission was later founded. The purpose is also to make a structure with very high performances and that is resistant to the aggression of termites (only hard wood is suitable there but it requires deforestation) without using steel since it is too expensive. So the final goal is not to send waste to Africa but to show how waste can also become a very solid structure and a valued asset.
