This paper focuses on roof structures consisting of radially arranged cables with a radial arrangement of cables 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 with a view to adopt this structure in Japan. In this paper, a method for calculating the equivalent static wind load for evaluating this structure by static analysis is proposed and its applicability is discussed.
