Keywords : unit-based tension structure, interaction, introduction of tensile force, stress control ��In order to realize reliable tension structures, it is very important to make an appropriate plan for introducing tensile force in its construction process. For this purpose, "Unit-based" structure is useful and convenient. Unit-based tension structure is a system that is composed of structural units stabilized by introducing initial stress. In this paper, a very simple method for introducing tensile force considering the interaction between units is proposed. After the influence of the interaction is studied with a very simple model, it is proved that the final stress condition is largely affected by the means of introducing tensile forces in each units. Finally a simple method is proposed and the validity is examined by some simulations imitating actual construction process with plane and three-dimensional models.

There are many structures that are controlled their shapes and/or stress distribution by being actively varied the length of their members. Some of the structures with vibration control system, so-called variable geometry trusses and many of the tension structures are examples of such structures. One of the difficulties in the design and realization of such structural systems is how to grasp the relationship between the member length change, and their shapes and stress distribution. In this paper a simple and effective linear inverse theory for the control of such structures is described. Then its validity is proved by showing some numerical examples and the comparison with the results of real scale tests of a tensegrity frame.�
