  • This unit - structure of truss stabilized by cable tension is composed of four truss member adding to a central post and eight cables, and is connected by hinge joints and is stabilized by cable tension. As this unit - structures itself is a statically closed and stabilize system individually, it can be employed to assemble a structure with a variety of configuration. In this paper, for determination the shape of the unit - structure of truss stabilized by the cable, characteristics such as the stabilized range of the various geometrical parameter about unit system and the relation of the best governing paramter is demonstrated, and the relation of the results is compared in the range for the stabilization of unit-structure.

  • The charateristics of stabilization for stabilized truss unit-structures with cable and truss are investigated in this paper. This unit system is composed of a central post and eight cables, and is connected by hinge joints, and stabilized by self-equilibrated stress field. As this unit structure itself is a statically closed and stabilized system individually, it can be employed to assemble structures with various configurations. In this study, for stabilization of truss structures stabilized by cable tension, the structural concept of unit structures, the range of various geometrical parameters and the relationship of governing parameters about unit systems are explained.

  • The primary objective of this paper is to grasp characteristics of unit system, for the stabilization of stablized truss structure that is an assemblage of unit system by prestress. This unit system is composed of a central post and eight cables, and is connected by hinge joints, and stabilized by the self-equilibrated stress system. As this unit structures itself is a statically closed and stabilized system individually, it can be employed to assemble a structure with a variety of configuration. In this paper, for the stabilization of truss structure stabilized by cable tension, it is proposed the self-equilibrated axial mode equation and the range of the various geometrical parameter about unit system.

  • The tensegrity structure by prestressed cable, which may have large freedom in scale and form and therefore are received much attention from the view points of their light weight and aesthetics, is a very flexible and geometrically unstable structure because the cable material has little initial rigidity. For the stable self-equilibrated state of the usually very deformable structure, the method to find the optimal initial stress by the shape analysis is proposed in this paper. The proposed procedure is to derive the nonlinear finite element formula of cable and truss members considering geometric nonlinearity and used to modified load incremental method adding to Newton-Raphson method with the proposed condition for optimal initial stress. The result of the shape analysis for the tensegrity structure with the radius of 30m is shown the almost approximated shape to architectural shape and the changed procedure of initial stress
