- Resumen
Deployable structures with articulated straight bars have the virtue of being lightweight, modular and transformable. This is how the architect Felix Escrig defined them, who left us a fantastic legacy on these structures. From the SMiA research group (Structural Morfology in Architecture) and specifically from this research, deployable systems focused on a real application have been developed. With the help of digital tools such as parametric design and digital manufacturing processes, this document describes a methodology design for deployable structures with articulated straight bars and develops a graphical tensile method to make simulations of movement control of these structures. To finally apply them to two case studies going through the design, manufacturing and assembly processes of prototypes on a 1: 1 scale.
A first part of this research describes the most notable and characteristic works in the field of deployable structures, focusing on articulated straight bars. Starting point in which it is proposed to make a geometric description of the deployable systems with articulated straight bars from the simplest deployable unit to complex deployable geometries and groupings. With the help of software such as Rhinoceros + Grasshopper, an algorithm library is made with deployable structures. Library used to make a proposal for the classification of deployable structures with articulated straight bars.
The second part of this document proposes a tension simulation method for limit control of movement of deployable systems. With the help of Grasshopper + Kangaroo an algorithm is developed that allows to control the final position of use of the deployable structures, and to make simulations of movement. The model allows to control and adjust the dimensions, asymmetries and angles of incidence for the deployable systems. As well as to foresee the design of the movement limit control elements.
Finally, in the third part of the investigation, two case studies are proposed with the aim of applying parametric design strategies and the traction simulation method to control the stability of deployable structures with articulated straight bars. The final scope is to build 1: 1 scale prototypes. The first case study is the D30, a 30-square-meter deployable dome. And the second case study is the Vertex pavilion, a 90-square-meter structure made up of 12 folding arches with a triangular section.
The purpose of this research is to make the leap to the construction of real-scale prototypes in order to provide constructive solutions to deployable systems, enhancing their application in architecture.
