Stadium roofs generally require a large opening in the center, and in recent years a roof structure consisting of radially arranged cables has been used in stadium construction outside of Japan. This structure is a lightweight structure in which cables are radially arranged between the inner tension ring and the outer compression ring. However, there are no cases adopted in Japan. In this paper, the authors investigate the effects of the roof configuration and initial tension on the wind response of this structure and attempt to expand the basic design data.
