“…Hereafter we proceed to list various approaches to tensegrity problems by mathematicians, architects, and structural engineers. Curiously and characteristically, these approaches span from Sakantamis and Popovic Larsen's [64], proceeding by manual construction of physical models, to De Guzman and Orden's [65] symbolic approach, supplied by an interesting theorem, which states that every TS can obtained from elementary units, referred to as atoms. Here are some other approaches.…”

We try to make a long way short by proceeding per exempla from Kenneth Snelson’s sculptures and Richard Buckminster Fuller’s coinage of the term tensegrity to modern tensegrity metamaterials. We document the passage from initial interest in tensegrity frameworks for their visual impact to today’s interest, driven by their peculiar structural performances. In the past seventy years, the early art pieces and roofing structural complexes have been followed by formalization of the principles governing the form-finding property of ‘pure’ tensegrity structures and by engineering hybridization leading to a host of diverse practical applications, such as variable-geometry civil engineering structures, on-earth and in-orbit deployable structures and robots, and finally to recent and promising studies on tensegrity metamaterials and small-scale tensegrity structures.

“…A related study on this kind of systems is presented in [25]. The procedure as described here can be viewed as an extension of the cocoon method introduced in [26]. In the present example we exploit and maintain the icosahedral symmetry of the system to simplify the form-finding procedure.…”

We consider here floating-compression tensegrity systems: prestressed spatial trusses, composed by cables and struts, such that struts are never connected to each other. In particular, we focus on single-layer systems: all the nodal positions are assumed to lie on a closed synclastic surface, such as a sphere or an ellipsoid. In this study we perform the form-finding and the structural design of a new tensegrity dome of small size; then we compare it to a conventional truss structure. Theoretically, floating-compression systems are not the best choice for carrying loads, a fact which is confirmed in this study. Nevertheless, our tensegrity design improves previous ones significantly. The structural performances evaluated here provide a reference point for assessing the feasibility of floating-compression systems.

“…12,13 Another building example is the tensegrity roof system designed for the roof of the central library, which was completed in 1995 in Phoenix, USA, where the hot desert climate prevails. 14 In the research on the tensegrity system, it is seen that subjects such as different geometric forms, [15][16][17] cable strain energy, [18][19][20][21] cable breakage situations, 22 damage situations, 23 tensegrity system static analyses, [24][25][26][27][28] and system movement against vibration [29][30][31] are intensively investigated.…”

SummaryTensegrity systems are construction system that offers solutions for lighter designs compared with a standard truss system consisting of tension and compression elements. Due to their structure, they are recommended in the design of space structures due to the use of lighter and easy‐to‐assemble structural elements such as cables, ropes, and similar to provide the desired durability. In this study, energy minimization was carried out to solve the structural element displacements. It is expected to reduce the total potential energy of the system with minimization. By minimizing the total potential energy of the tensegrity system models, the displacement of each building element is found for the equilibrium condition. Tensegrity models were analyzed by minimizing energy via the adaptive harmony search (AHS) algorithm. In this research, two distinct tensegrity structure specimens were employed. One comprised a cantilever beam, while the other adopted a cyclic model, forming eight equal octagons from eight nodes at both the base and the top. Additionally, an examination was conducted on a two‐layer iteration of the cyclic model. The method is robust for both space and planar tensegrity structures, allowing the determination of deformed shapes under various loads without design assumptions. The TPO/MA method demonstrates superiority in handling nonlinear and barely stable systems, as evidenced by examples illustrating its efficacy in maintaining structural form under increasing loads and challenging conditions.
