Abstract
The concept of 'Tensegrity' composed of the struts and the strings was invented by B. Fuller, and D. Geiger developed the system as Cable Dome with fabric roofing. In these structures, the importance of existence of the pre-stressing is indicated. In this study, we propose Tension Strut Dome (TSD) which is similar to a Cable Dome, but different with the origin of itsconcept. This structural system is composed of cable girder with radial form and tension ring truss. This paper reports an example of Tensegrity Tower and the structural principle of TSD which has the characteristics of the pre-stressing mechanism and the lift-up construction method.
