Abstract
In general, structural behavior of tensegrity structures under load is often calculated with representing members as simple line members. However, in the construction phase, it is necessary to consider the thickness of members and the real dimension of the connections. This leads us to pay attention to the rigid body motions of members, especially the rotation of the straight members around its axis. In this paper, the conventional compression members calculated as truss members are reconsidered as beam elements having six degrees of freedom. Then the angle change of the members during construction is studied. The upper part joints in the structure are designed as hemispheres, relative calculations are also necessary.
