Abstract:The general situation of Chiping Stadium was introduced. The structural form selection of the cablestayed modeling of the roof was focused and the cablestayed doublelayer reticulated shell structure was adopted in roof system. The analysis model of the cablestayed doublelayer reticulated shell structure was established by SAP2000. Static and dynamic analyses were completed under various load combinations to obtain the static responses of components and dynamic properties of the whole structure. Analysis results show that the relevant indexes meet the requirements, which verifies the feasibility of structural form selection. Finally, the key joints of bearings and cable connections were designed to ensure the efficient force transmission between composed parts of the whole structure.

Keywords:cablestayed doublelayer reticulated shell; SAP2000; static and dynamic analysis; key joint
