【提要】 北京中关村软件园“光盘”结构造型独特，对风荷载比较敏感，规范没有给出其设计风荷载取值。采用刚性测压模型对单独的“光盘”体及“光盘”与周围建筑的组合体进行了风洞试验，考虑高度换算系数和体型系数，对“光盘”结构的风荷载特性进行了探讨，结果表明，在结构设计中应该充分考虑风荷载的实际分布，应对多种风向角对应的风荷载分别进行整体结构分析。

Wind Tunnel Test on Disk Canopy Structure in Zhongguancun Software Plaza/Zhang Tongyi1,Gu Zhifu2,Xiao Ziqiang1,He Wei1(1 IPPR Engineering International,Beijing 100089,China; 2 Beijing University,Beijing 100871,China)
Abstract:The appearance of disk canopy structure in Zhongguancun software plaza is unusual,and the structure is sensitive to the wind load.The wind load is not given in the design code.With the rigidity compression test model,the wind tunnel tests are conducted on the single disk canopy system and the combination system of disk camopy system and the around buildings.The wind load characters are discussed based on the height conversion coefficient and structural shape coefficient.The results show that the actual load distribution should be considered in design,and ntegral structure analysis related to the multi wind direction angles is necessary.
Keywords:wind load； wind pressure coefficient; shape coefficient; tunnel test
