abstract = {The text presents a new type of stress-free deployable structures (meaning that they do not present geometric incompatibilities during the folding-unfolding process), the sailor vault of equal scissor-like elements, SLE. The geometric generation process is explained, establishing the concepts of eccentricity and opening angle of the SLE based on the final deployed situation. The deployment process is then studied employing a dynamic calculation program. Having overcome these issues, the construction of a physical model for testing is addressed, using reciprocal joints to improve the structural behaviour. An account is given of the modifications introduced during the construction process to achieve a model with good mechanical behaviour. Finally, a test campaign is carried out on this model, consisting of load tests of the model on four and eight supports subjected to vertical ascending and descending loads. The results of these tests are contrasted with those acquired with a computer model. The values obtained are analysed, drawing interesting conclusions with a view to their practical application. Although equal-bar deployable domes are very simple from a construction point of view, they must comply with strict design mechanisms. In order to be structurally effective, they must have sufficient camber, which in the models tested has been achieved using SLEs with an eccentricity of 5.15% and an opening angle of 30°, as well as the subsequent addition of a series of complementary bars that depend on the support system. The use of reciprocal joints radically improves the behaviour of the structure, but construction tolerances have only allowed to place them on the outer face.},

abstract = {This article describes a new deployable structural system referred to as a dual-folding multiple cross-arch cylindrical vault. The development of the system is described, based on the methodology detailed by the authors in a previous article, resulting in novel and interesting designs. The structural details designed to allow the folding and deployment movements are also described. Several models of the above elements built on a reduced scale are presented. Finally, a complete ¼-scale aluminium model of the structure was built to verify the kinematic conditions of folding and deployment. Deformational tests have been carried out with this model under gravitational load, which are also presented in this article, validating the viability of the system.},

abstract = {Deployable structures are an ideal solution for emergency buildings because of their lightness and compactness, allowing them to be transported to wherever they are needed. Generally the most frequent solutions use Scissor-like-Elements (SLE), but in this case the use of bundle modules is proposed. These systems were developed by Pérez Piñero, but have hardly been used since then. The article analyses the problems they present, as well as their advantages in reducing the number of bars and linkages required, which allows for the design of simpler and more economical structures. The geometrical and mechanical conditions of the linkages for triangular and square modules are analysed, as well as the typologies that may arise. A calculation method is also developed to analyse this type of structure. Finally, the performance of a flat grid is analysed in an analytical and experimental way using reciprocal links at its ends. Both theoretical calculations and experimental tests allow us to demonstrate the viability and efficiency of this new type of structure.},
