Abstract: The steel roof, designed for Main Stadium of Shenzhen Universiade Sports Center is composed of single triangular gridding by folding method, and is made the best of tensile and compressive bearing capacity of steel tubular. This saddle structure is a new structural design, called single layer folded plate dimensional gridding structure. The experience could be applied to practice for structural engineers.
Keywords: single layer; folded plate; dimensional gridding
