“…Moreover, in previous research it is stated that traditional scissor elements show a low to medium structural efficiency due to existing bending moments [8]. But this first structural calculation proves that the designed USC rather excludes bending moments, thus increasing the structural efficiency of the structure.…”

Non-static structures that can adapt their shape, or which can be quickly and easily deployed to perform their architectural function and removed afterwards without damaging sensitive sites, are well-equipped to meet the demands of a rapidly changing society which embraces the concept of sustainable design.Generally, mobile deployable structures are capable of transforming from a small, closed or stowed configuration to a much larger, open or deployed configuration. In architecture, the main applications are temporary lightweight structures such as emergency shelters or exhibition and recreational structures. For these purposes deployable scissor structures are most effective. They consist of beam elements connected by pivot joints, allowing them to be folded into a compact bundle for storage or transport. Subsequently, they are deployed, demonstrating a huge volume expansion. This process can be reversed, allowing reuse.In this paper an innovative kit-of-parts system is developed for deployable scissor structures. A new multi-configurational Universal Scissor Component (USC) is geometrically designed to create scissor structures in a generic way. The designed USC -single and unique -is used to compose different configurations. The structures can be disassembled and the USC can then be reconfigured, enabling reuse (cfr. the toy construction system Meccano). The component's uniformity favours mass-production, implying a cost benefit. Moreover, the diversity in possible structural forms invites multiple uses.

“…Deployability allows the instantaneous opening or closing of a structure to transform it from a compact configuration to an expanded, functional space enclosure [2]. As with plants or even animals in nature, this volume or surface expansion allows capturing or protecting from the sun, the rain and other environmental factors.…”

Living in an age of rapid changes, designers are challenged to create solutions that remain sustainable in a continuously evolving environment. Since most of our earth's resources are finite, these solutions should incorporate efficient material use and reuse. Buildings and structures are always in transition. Facilitating these transformations is vital to the sustainable development of our built environment. With our group we study, develop and assess transformable structures on different scales, in different contexts and for various time-spans and purposes. This paper presents our work on transformable structures, based on four case studies: a kinetic curved-line folding component, a temporary and rapidly assembled structure, a dynamic wall assembly and a BIM tool for material flow assessment of adaptable buildings. Although varying in scale or purpose, these cases demonstrate the same key principles of transformability. Reducing the complexity of the connections and structural system facilitates an easy and rapid assembly, but also allows users and locals to participate in the assembly, maintenance, reconfiguration and deconstruction of the structure. Apart from benefits during the assembly and adaptability, it is important to assess transformable structures and building solutions on their material and cost effectiveness. With BIM tools it is possible to incorporate this assessment already in the conceptual design phases of a project, as illustrated in the fourth case. Keywords: BIM, deployable structures, design for change, kit-of-parts structures, material flows, prototyping, transformable structures. INTRODUCTIONThe complex nature of our built environment subjects it to continuous evolutionary processes. The subsequent changes in cultural trends, global markets and technological innovation increasingly lead to resource depletion and waste production, and thus endanger the self-sustaining nature of our planet. Because most of the earth's mineral and fossil resources are finite, they should be used and reused wisely. Designers are challenged to create solutions that remain sustainable in a continuously changing context. The structures of the built environment in which we operate are never end states, but phases of a process. Facilitating transformations is vital to sustainable development. This requires holistic approaches that take change into account and help alleviate future problems.By introducing transformational capacity at different design levels, we want to maximise the sustainability of settlements, structures and components through time while minimising the waste of resources. We believe that transformability can act as an important catalyst for sustainable development because of the social, economic and ecological qualities it generates over time and the life-cycle resource management it incorporates. With our research group, we study, analyse, design and assess transformable structures varying in scale, context, timespan and purpose. This paper discusses the main principles of the develop...

“…Equally, many deployable structures can reverse the process or retract [2]. The classification table by Hanaor and Levy [3] illustrates the variety of deployable structures that include scissor-hinged structures [4,5]; folded plates, often linked to the science of origami [6,7]; tensegrities, based on the separation of the tensile forces from compression ones [8,9]; and membrane structures, such as boundary tension membranes and pneumatic structures [10,11].…”

The methodology for the analysis of deployable structures with 2 degrees of freedom (DoF) and optimisation of the deployment sequence is proposed. A parametrically controlled geometry, based on the design of biomimetic deployable structures, is systematically cycled through all available combinations of deployment and analysed for the full range of available motion established by the two DoFs. In other words, structural analysis is carried out for all potential configurations for the 2 DoFs, which act independently from one another. The results are, then, automatically post-processed to give contour plots showing the change in performance criteria such as the force or moment that develops in the structure during deployment. Knowing that the structure needs to deploy from the fully folded to the fully unfolded state, the generation of convex hull profiles allows the selection of the optimum path to reach the fully deployed state based on whatever the governing criteria is deemed to be, such as maximum deployment force, deflection, weight of structure, or in service stresses.
