Deployable bundle modulus structures with reciprocal linkages for emergency buildings

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