Expandable covers of skew modules for emergency buildings

Abstract

Deployable structures can be a good response to disaster situations, where it is necessary to provide services to a displaced population. They can be compacted into a lightweight and easily transportable package and deployed where needed providing an enclosure for use, quickly and efficiently. In this article, the possibilities of deployable structures of oblique modules are investigated, a subject little studied, but of great interest due to its many possibilities. The geometric conditions of the different modules and the typologies that can be considered are analyzed. The possibility of using the reciprocal links system developed by the authors is also studied in these meshes. Finally, the performance of a pyramidal dome that uses reciprocal linkages at the ends of its bar, is analyzed in an analytical and experimental way. Both the theoretical calculations and the experimental tests allow demonstrating the viability and effectiveness of this structural type.
