Abstract. The use of a principle of the self-stressed «tensegrity» structures in architecture and construction is considered in this article. The concept of tensegrity is characterized in architecture as a set of interrelated elements that work only on tension or compression. The term «tensegrity» is formed from two words «tension» and «integrity», that is, the tensegrity constructions are such ones, integrity of which is provided by the creation of initial tension of the elements. The idea of the self-stressed constructions can be considered as a kind of bionic approach, i.e. the way of using structures created by nature as a prototype for making engineering structures. In Part 1, the authors analyzed the main properties of tensegrity structures and showed their disadvantages and distinctive features. The concept of «tensegrity» constructionss is defined as a set of design principles: the stressed elements are in a state of either pure compression or pure tension. That is to say that the structure consisting of these elements can collapse either as a result of cable break or due to bar buckling. The pretension stifens the ropes during behavior both in tension and in compression. The design has a mechanical stability, allowing its elements to remain in a tensioned or compressed state, even with increasing stresses in the elements of the structure.

Keywords: self-stressed systems; tensegrity; compressed-tensioned systems; architecture of tensegrity systems; tensegrity modules
