Abstract: Abstract： Taking the great building “Clouds of Celebration” which is a part of Shanghai World Expo Museum as the object, numerical simulation techniques were utilized to investigate the wind pressure distribution, the gust factors (GFs) and the equivalent static wind loads (ESWL) of the complex multibody spatial structure with consideration of mutual interference of wind fields around surrounding buildings under different incoming wind directions. Besides, the wind pressure nephograms and local zone pressure coefficients were discussed, the gust factors were obtained by means of the peak factor method, and the ESWL were determined, taking the most unfavorable incoming wind directions into account.

Key words: Key words： multibody structure, wind pressure distribution, gust factor, equivalent static wind loads
