A Methodology for Optimal Design and Simulation of Deployable Structures

Abstract

Abstract Deployable structures with bars have been used in different technological fields since the beginning of the 20th century. It was as of 1930 when their use in construction became widespread, especially in roofs with large spans. The research group at San Pablo University in Madrid, along with Keene State College has developed a new type of deployable structure that minimizes the weight and maximizes the span. The structural efficiency is based on the fact that the tensioned elements of the modules are made of cables. In addition to contributing to the overall stiffness and strength of the structure, these cables are designed to guide the folding and unfolding process of the structure. In each module the tension cable is extended until it is connected to the midpoint of the compression bar, thus regulating its position and avoiding the possibility of unforeseen folding while the structure is fully deployed. This article shows a method to optimize the geometry and to test the static behavior of the structure.
