“…Ten-stage tower-like tensegrity has been investigated by using dynamic relaxation method by Zhang and Ohsaki [7] whereas Masic et al studied six-stage tower-like tensegrity by using algebraic approach [21] which adopted force density method in the form-finding process. Oh et al suggest the tapered three-stage tensegrity model searched in the study for deployable structure [22]. Figure 1(h) shows an arch tensegrity structure successfully searched by using dynamic relaxation method.…”

This paper presents an overview of the previous research on the form finding structures which include tensegrity and biotensegrity structure. Tensegrity systems have been widely used for many applications due to the stability and flexibility of the structures. On technologies era nowadays, a stable structure is needed to implement for new developments especially robotics and machineries. Therefore, the importance of finding the shape or design configuration is to ensure it is in self-equilibrium which able to support itself. In order to build new structures which lies on general requirement, previous researchers have proposed several form-finding methods for instance by using force density method, advance force density method, finite element method, dynamic relaxation method, genetic algorithm, novel linear approach and Monte Carlo method. What kind of stable structures can be produced and how efficient the structures by using those methods? In this paper, understanding on the form-finding methods and various numerical examples of form-finding conducted in previous studies are presented to enhance researchers’ knowledge on the form-finding of tensegrity structures.

Tensegrity structures is a light-weight structure compared to concrete structures that are heavy and rigid in shape. The studies on form-finding for tensegrity configuration are still ongoing and have been extensively conducted. Additionally, many proposed tensegrity structures have not been built for real applications. This study aims to determine potential self-equilibrated configurations of three-stage Class I tensegrity model assemblage with triangular cells, which may be applied as deployable towers. The form-finding methodology involves phases in establishment of desired form and formulation for the self-equilibrated state. The system of equilibrium equations was solved by Moore-Penrose generalized inverse method. A range of twist angles 10o – 50o for triangular cells was investigated in the form-finding process. It was found that the form-finding method via changing of twist angles has successfully search self-equilibrated tensegrity models.
