Abstract: The plane size of swimming stadium of Ningbo Olympic Center is 219m×103m. Reinforced concrete frame structure is adopted in lower main structure, the upper steel roof adopts different structural forms according to different spans and supporting conditions, including pipe truss structure and rectangular steel tube folded-line rigid frame structure. It mainly focused on the treatment measures for some key technical problems of structural design, including structural oriental analysis, seismic performance-based design, comfort analysis of large-span floor, super long structure design and special-shaped diving platform structure design, etc. The results show that the selected structural system is reasonable, safe and reliable, and the calculation results of the upper steel roof and the lower concrete supporting structure can meet the requirements of the specifications. 

Keywords:Ningbo Olympic Center; swimming stadium； oriental analysis； over-length concrete structure； temperature stress； performance-based seismic design
