“…Tensegrity plates composed of Quartex modules were considered, among others, by Wang and Xu [22], Faroughi and Lee [23] and Sulaiman et al [24] (Figure 2). Wang and Xu used semidefinite programming (SDP) to determine the optimal topology of the tensegrity plate-like structure consisting of nine modules.…”

The study includes parametric analysis of special spatial rod grids called tensegrity plate-like structures. Tensegrity structures consist of only compression and tension components arranged in a system, whose unique mechanical and mathematical properties distinguish them from conventional cable–strut frameworks. Complete analysis of tensegrity structures is a two-stage process. The first stage includes the identification of self-stress states and infinitesimal mechanisms (qualitative analysis). The second stage focuses on the behaviour of tensegrities under external loads (quantitative analysis). In the paper, a qualitative analysis of tensegrity plate-like structures built with modified Quartex modules was conducted. Starting from a single-module structure, more complex cases were sequentially analysed. The different ways of plate support were considered. To carry out a qualitative assessment, a spectral analysis of the truss matrices and singular value decomposition of the compatibility matrix were used. The characteristic features of tensegrity structures were identified. On this basis, the plates were classified into one of the four groups defined in the paper, i.e., ideal tensegrity, “pure” tensegrity and structures with tensegrity features of class 1 or class 2. This classification is important due to different behaviours of the structure under external actions. The qualitative analysis carried out in the paper is the basis for a quantitative analysis.

Structural systems based on tension and compression play a significant role in maximizing the performance of materials. Among them, structures based on the concept of tensegrity have attracted attention owing to their elegant design features and floating feeling. However, the complex construction of tensegrity-based structures hinders their implementation in practical design and architectural applications. Herein, we propose a novel tensegrity-based unit with simple connectivity and manufacturability. The external form of this unit is similar to that of a space-filling polyhedron. The prototype of the proposed unit is constructed, and the simple tension management of the unit is demonstrated. The mechanical behavior of the assembled structure is investigated by performing loading tests and numerical analyses. The behavior can be accurately predicted and general design can be applied to develop structures for practical applications.
