Self-equilibrium stress mode analysis of multi-stage tensegrity structures by eigenvalue problem is presented, In order to maintain the structures stable, "state of self-equilibrium stress" should be introduced. The types of analytical methods are known to solve this phenomenon: One is to use force density method, and the other is to apply so called, generalized inverse method. In this paper, new form finding methods are presented to obtain the self-equilibrium stress of the tensegrity structures. These methods are based on the equilibrium equation of the all of the joint and the governing equation is formulated as eigenvalue problem. In order to verify this approach, multi-stage tensegrity structures based on results of unit module are compared with others calculated by previous methods. The solution by present method is shown identical results. Furthermore, the developed process to find the results is more efficient than previous approaches.
