This paper focuses on roof structures consisting of radially arranged cables placed between the inner tension ring and the outer compression ring. Although many examples of the adoption of this structure have been reported outside Japan, no actual examples have yet been reported in Japan. Therefore, the authors are conducting this study with the aim of preparing structural design documents. In this paper, a study is conducted to propose structural behavior and wind load assessment methods for this structure in strong winds, taking into account roof deformation, and to expand basic design documents.
