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
