摘要： 摘要： 以上海世博会后的世博博物馆“欢庆之云”复杂形体大跨度新建工程为背景对象，运用数值模拟方法，研究在不同风向角来风且存在周边建筑风场干扰的情形下，表面曲率多变的多连体大跨空间建筑结构的表面风压、阵风系数和等效静风荷载.对风压云图和分区域风压系数进行了分析，并基于峰值因子法求解阵风系数，进而提出了考虑最不利风向角的等效静风荷载.

关键词: 多连体结构, 风压分布, 阵风系数, 等效静风荷载

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
