Abstract: The main structure of the Stadium in Chengde Olympic Sports Center is reinforced concrete frame with a large-span space frame structure. There are 24m-span beam and 27m-span beam which were prestressed concrete beams above the training hall. The analytical model is consisted of roof steel structure and concrete structure, and the two kinds of structure were analyzed separately. In order to assure the safety of the structure, varies structural analysis on the space frame structure had been camed out, include different analytical model and space frame structure out plane stability.
Keywords: stadium; space frame structure; prestressed concrete beam; stability analysis
