Comparison between new families of Double-Layer Tensegrity Grids

Abstract

Rot-Umbela manipulations permit conventional double-layer grids (DLG) to be transformed into tensegrity grids. By means of this method, two new tensegrity modules (Quastrut and Sixstrut) were already discovered. The aim of this work is to compare the behavior of the new family of Double-Layer Tensegrity Grids (DLTG) obtained by the juxtaposition of the Quastrut in some of its variations depending on enantiomorphic variants (e.g. monogyre Vs. racemic), orientations (e.g. 0º Vs. 90º) and configurations (e.g. open Vs. closed). It will be possible to determine which DLTG performs better taking into account their resistance, structural efficiency, deflection, etc. Furthermore, analysis of their mechanisms and states of self-stress could help to understand their structural characteristics better. Deployability will be revealed as one of the most challenging and interesting potentials of these DLTGs.
