[摘要]  介绍了中国航海博物馆的模型风洞试验概况和主要试验结果。对代表性结构部位风压系数的研究表明，由于体型复杂，加之主要构件之间存在严重的干扰效应，结构风压分布具有很强的个性特征，非常复杂。给出了风压分布的基本特征，并进行了分析。对围护结构的表面风压分别采用规范方法和统计方法进行了分析比较，结果表明，两种方法计算结果差异较大，在对围护结构进行设计时，应综合考虑上述两种方法，给出安全合理的设计荷载。

Abstract:  lt introduces briefly the testing conditions and main results of the wind tunnel test of a museum. The wind pressure distributions over the structure show very complicated feature due to the complex structural configuration and furthermore the interference effects between its main structural members. The basic characteristics of the wind pressures are presented and discussed. Finally, the wind loads for cladding design are computed using the code metbod and statistical approach, which shows that there is a rather big difference between the design wind loads from the two appmaches.  Accordingly, a combined consideration of the above mentioned methods should be duly made to provide the safe and proper design loads for the structure.
