Abstract:The two stadiums of Bohai International Convention Center, one natalorium and one gymnasium, are located in Caofeidian Economic Development Zone. The two gymnasiums are 16 000m² and their roofs are designed as membrane structures. A 3D modeling method for complex space structure is introduced. As membrane structures are wind-sensitive, the wind tunnel test is done and the wind-induced dynamic coefficients are calculated. The random wind response analysis are done and wind-induced vibration coefficient are calculated. The integrate buckling analysis of the shell and the analysis of the membrane and  steel roof structure are done. The analysis results prove that the whole structural design are safe and up to the code.

Keywords:gymnsium; arch shell; membrane structure; wind tunnel test; wind-induced vibration; integrate buckling; analysis
