Abstract:The swimming and diving hall of Xi’an Olympic Sports Center is a multi-functional stadium integrating swimming, diving, synchronized swimming, water polo competitions, and cultural and leisure activities. The bottom is a reinforced concrete frame structure and the roof is an inverted triangular three-dimensional tube truss structure. Several key parts design of the swimming and diving hall was introduced. Through the comparative analysis of the stiffness schemes simulated by SAP2000 software, the simplified modeling method of the prefabricated grandstand board in the conventional software was summarized, and the adjustment coefficient of the prefabricated grandstand on the effect of the main structure of the long and short columns was proposed. The synergy of purlins and three-dimensional trusses was explained on the roof system analysis, without the need to install longitudinally stable trusses. The comfort control of the super-large-span floor slab should be comprehensively determined by a combination of software simulation analysis and on-site measurement. The control points of the competition pool and the jumping tower for hosting international competitions, etc. were introduced.
