Dynamic Relaxation Method

This paper presents a practical application of form-finding process of cable-membrane structures. The dynamic relaxation method with kinetic damping is used as the computation method for numerical analysis. A brief description of the construction, a description of the models and the way of solving tasks will be introduced. The correct operation of the implemented algorithm will be compared with a commercial program.

Tensegrity Systems

Tensegrity systems are structures in which morphological and mechanical aspects are closely related by selfstress requirements. In the first part, this paper describes the birth of the idea which led to these systems. Snelson's work seems to be the main contribution for their initial design, even if Fuller created the word tensegrity and contributed with other searchers, like Emmerich to the popularization of these systems. The second part is devoted to form-finding methods which are necessary to reach a morphology compatible with mechanical requirements. References for main computation methods are given. Among them numerical methods like force density method could constitute an useful design tool.

Search Condition

This paper is concerned with the selected aspects, which are discovered during a design stage of cable and membrane structures, known as “form-finding” process. The aim of this paper is the understanding of the basic principles of the form-finding process and their explanation of the very simple examples. The use of the finding a shape of a tension membrane that is in static equilibrium as an analogy with the search condition of minimal surfaces is explained. The basic principles are demonstrated on simple 2D example, in which the finding a stable minimal surface passes in the finding a stable minimal length.
