La siguiente investigación se desarrolló sobre las cubiertas plegables, donde se abordó el tema de los factores de cargas en dichas cubiertas, ya que este tipo de estructuras no se encuentra del todo normadas, por lo que se contemplan combinaciones experimentales de carga para el diseño de cubiertas no transitables, que se establecen en el Reglamento de Construcción del Distrito Federal (RCDF—2014), y el manual de diseño por vientos de CFE (MDVCFE—2015). Se revisa las cargas combinatorias con un software llamado WinTess, que realiza simulaciones estructurales contemplando una membrana estructural como rigidizador. El resultado será el dimensionamiento de la estructura.

The use of expandable structures in the field of building began in the 1960s, based on the pioneering work of Emilio Pérez Piñero. They underwent significant developments at the end of the 20th century, with typologies based on scissors or bundle modules. Until now, this typology has not been further enhanced, despite some very interesting contributions.<br/> These studies are usually based on straight bar expandable structures, although there are some interesting proposals based on the deployability of parallel arc systems, even in real buildings. However, other possible types of expandable structures have not been explored to date.<br/> In this paper, a new system for expandable structures is proposed, which opens new and interesting design possibilities based on the same folding principle. The system consists of deploying elements such as arches or frames with multiple intersections. Solutions for cylindrical vaults with horizontal axis joints and more complex geometries such as conoids are proposed, as well as domes with vertical and horizontal axis joints. Finally, other structures with special kinematic compatibility difficulties, such as concentric domes or toroids, are also studied.

“…After the death of Pérez Piñero, this research almost came to a standstill until the 1980s, when the first studies were carried out by Escrig et al, 4 Escrig 5 and Escrig and Pérez-Valcárcel 6 using scissor modules. The geometric and kinematic conditions of these structures were the subject of numerous studies as well as the calculation systems.…”

The use of deployable structures in architecture began in the 1960s, based on the pioneering work of Emilio Pérez Piñero. It has had an interesting development using bundle or scissor modules, but with solutions that are always based on through-bolted joints. In this document, a new system for deployable space grids is proposed. This new system is based on the use of self-lockable joints, opening up a new and interesting field of design possibilities. The resulting space grids can be deployed by means of joints arranged on the bars that have a self-locking mechanism which is engaged in the final open position. This configuration overcomes the significant buckling that is characteristic of deployable structures with through-bolted joints. Different solutions are proposed for various uses, and the data from the theoretical and experimental analysis are provided.
