Abstract. The paper considers methods for searching for the formation of self-stressed structures that can be used as a structural basis for industrial and transport structures, including bridge structures. In view of the special interest in self-stressed structures as promising variations of cable-stayed structures, the methods of preliminary design of the initial forms of future self-stressed structures are considered and analyzed, namely, the forms of searching for the initial forms of geometric configurations are studied by the example of several well-known methods. Examples of practical application of self-stressed systems in several structures are also demonstrated. Possible variations in the use of self-stressed structures in the work of building structures, including bridge structures, are noted. Methods for searching for self-stressed structures are given, taking into account certain input and desired parameters of the structure, namely static and kinematic methods. The features of searching for an equilibrium tensegrity structure based on these methods, as well as their joint application, are considered. There are also some advantages and disadvantages from certain points of view of finding the most correct tensegrity structure. Examples of joint application of some calculation methods in practice and their influence on each other in the calculation process are considered. Some basic examples of creating individual elements of self-stressed structures using schemes and formulas based on geometric and physical-mathematical parameters are given. The considered methods are also briefly analyzed from the point of view of their usefulness.
