Abstract: The national olympic center general physical training gymnasium is built for the training of the national judo team,wrestle team and tennis team for the 2008 olympic games. It consists of accessorial buildings and physical training gymnasium. The physical training gymnasium consists of three two stories large span frameworks, and it belongs to large span and spacial structure. The concrete structure, steel and concrete composite structure- steel structure were analyzed and compared in detail. Considering the floor structure setting,the more reasonable steel frame with V style brace system was adopted. During the roof design, combined with the functional demand,the novel hyperboloidal roof with prestressed cabled truss system was adopted. The analysis softwares PMSAP and ANSYS are used during the design course.
